Global Navigation Satellite Systems (GNSS) provide precise positioning and timing services across the globe. Central to their functioning are two key datasets: the almanac and the ephemeris. These provide crucial information about the orbits and status of the GNSS satellites. This article will delve into the roles of the almanac and ephemeris in GNSS operations along with an understanding of different GNSS receiver start modes: "cold", "warm", and "hot". These concepts are essential for professionals working with GNSS technology and for anyone interested in its principles.

GNSS Almanac and Ephemeris

To understand the start modes of a GNSS receiver we first need to comprehend the roles of the almanac and ephemeris.

• Almanac: This is a set of general data about the orbits of all GNSS navigation satellites. It offers a broad overview of where each satellite should be at any given time.
• Ephemeris: These are precise data sets specifying the orbit parameters for a specific satellite at a specific time. Ephemerides are necessary for the accurate positioning calculations done by GNSS receivers.

When a GNSS receiver is switched on it starts establishing connections with the navigation satellites. The first connected satellite transmits the almanac which gives the receiver a general idea of where all the satellites are located.

To determine precise coordinates, however, the receiver needs to connect with at least four satellites. Each of these satellites transmit their ephemeris to the receiver allowing it to perform precise positioning calculations.

GNSS Receiver Start Modes

The time it takes for a GNSS receiver to provide accurate positioning data after being turned on can vary based on the available data in its memory. This leads us to three distinct start modes: cold, warm, and hot.

• Cold Start: This occurs when the receiver lacks or has outdated almanac and ephemeris data. The receiver must obtain the almanac from the first satellite it connects with followed by the ephemeris data from at least four satellites. The time taken to gather this data and calculate coordinates is why this start is referred to as "cold" - the receiver needs time to "warm up" and prepare for work.
• Warm Start: In this case, the receiver has an up-to-date almanac but lacks current ephemeris data. It must connect with satellites to acquire this data before it can calculate precise coordinates.
• Hot Start: This happens when the receiver has both up-to-date almanac and ephemeris data in its memory. It can quickly establish connections with satellites and calculate coordinates without delay.

Almanac data is typically valid for up to 90 days while ephemeris data is valid for about 30 minutes due to its precise nature. Therefore a "hot" start can only occur if the receiver was powered off for a short time.

Conclusion

Understanding the roles of the almanac and ephemeris along with the different start modes is crucial for effectively working with GNSS receivers. This knowledge enables us to comprehend the operational dynamics of these devices and helps predict the time taken for accurate positioning. As we continue to rely on GNSS for various applications such understanding becomes increasingly valuable.

Surveying equipment is a critical tool in many industries including construction, engineering, mining and land surveying. The equipment is used to measure and map land, structures and infrastructure providing essential information for project planning and development. For instance, in the construction industry alone, surveying equipment is used in 85% of all construction projects worldwide highlighting its importance.

However, the effectiveness of surveying equipment depends heavily on the knowledge and skills of the people using it. A survey by Trimble found that up to 50% of construction professionals lack adequate training in surveying equipment operation and maintenance indicating a significant knowledge gap in the industry. This gap can lead to inaccurate data, costly errors and even safety hazards on the job.

To address these issues, ongoing training for surveyors and construction engineers is crucial. By providing regular training and education, surveying equipment users can stay up-to-date with the latest technology and techniques which can improve accuracy, efficiency and safety on the job. Furthermore, ongoing training can help surveying equipment users maintain their certification and stay competitive in the job market.

In this article, we’ll explore the importance of ongoing training for surveying equipment users and the benefits it provides for accuracy, efficiency and safety on the job. We’ll also discuss common training methods, the importance of certification and provide examples of companies that have invested in ongoing training.

The Benefits of Ongoing Training

Ongoing training for surveying equipment users provides numerous benefits that can help improve the accuracy, efficiency and safety of surveying work.

Firstly, ongoing training helps improve the accuracy of surveying work by keeping users up-to-date with the latest technology and techniques. Surveying equipment is continually evolving and ongoing training ensures that users are aware of the latest advancements and how to use them correctly. This knowledge helps users to produce more accurate and reliable results which is essential in industries such as construction and engineering.

Secondly, ongoing training improves the efficiency of surveying work. By learning new techniques and tools surveying equipment users can perform their work faster and with greater precision. This can help to reduce the time required for data collection and analysis ultimately resulting in cost savings for the organisation.

Thirdly, ongoing training improves safety and reduces the risk of accidents on the job. Surveying work often involves working in hazardous environments such as construction sites, highways or railways. Proper training ensures that surveying equipment users are aware of the hazards and how to mitigate them. This knowledge can help to prevent accidents, injuries and even fatalities on the job.

Common Training Methods

There are several training methods available which include product-specific training, on-site training, online courses and workshops.

Product-specific training focuses on teaching users how to operate and maintain specific surveying equipment. Manufacturers often offer product-specific training to their customers either through on-site training or online courses. For example, Trimble offers a range of online courses on their Trimble Knowledge Center covering topics such as surveying workflows, data management and machine control.

On-site training involves a trainer visiting the organisation's site to provide training to the employees. The trainer may use the organisation's own surveying equipment to provide hands-on training. On-site training is convenient for organisations as it reduces the cost and time required to send employees to an external training facility.

Online courses are another popular training method for surveying equipment users. Online courses provide a convenient and flexible way for users to learn new skills and techniques. Users can access the courses from anywhere and at any time allowing them to fit training around their work and personal schedules. Trimble offers a range of online courses through their Trimble Knowledge Center, including courses on surveying workflows, data management, and machine control.

Workshops are another training method that is popular with surveying equipment users. Workshops are short, intensive courses that focus on specific topics or technologies. For example, Topcon Positioning Systems offers a range of workshops on topics such as total station operation, data collection and machine control. Workshops are typically conducted in small groups allowing for more personalised training. Workshops provide hands-on training and the opportunity to interact with other professionals in the field. However, workshops may require travel expenses and can be time-consuming.

The Cost of Ongoing Training

Despite the numerous benefits of ongoing training for surveying equipment users, some companies may be hesitant to invest in it due to the associated costs. Training can be expensive and some companies may not see the immediate benefits of investing in it. Additionally, training can take employees away from their work for a period of time which can result in lost productivity and additional costs for the organisation.

However, the cost of ongoing training can be outweighed by the many benefits. Investing in ongoing training can help companies to reduce the risk of errors and inaccuracies in their surveying work, which can save the company money by reducing the need for rework or revisions, which can be costly and time-consuming. For example, if a surveyor makes a mistake while conducting a land survey and the mistake is not detected until after construction has begun, it can cost the company thousands or even millions of euros to correct the error.

Investing in ongoing training can also improve the efficiency of surveying work reducing the time required for data collection and analysis. This can result in cost savings for the organisation as the same amount of work can be completed in less time. For example, if a surveying team can complete a project in two weeks instead of three weeks the organisation can save money on labour costs and other expenses associated with the project.

Finally, investing in ongoing training can improve safety and reduce the risk of accidents on the job. This can save the organisation money by reducing the costs associated with workplace injuries such as medical expenses, workers' compensation and lost productivity. For example, if a surveyor receives training on how to properly use safety equipment and prevent falls, the organisation can reduce the risk of injuries and avoid the associated costs.

The Importance of Certification

Certification is an important aspect of ongoing training for users worldwide. It demonstrates that a surveyor has the knowledge and skills necessary to perform their job safely and effectively. It also provides assurance to clients that the surveyor is qualified to perform the work required.

In Northern Ireland, surveyors must meet certain requirements to become licensed. To obtain a licence, surveyors must hold a degree in surveying or a related subject, complete two years of practical training, pass an exam and meet certain professional requirements. To maintain their licence, surveyors in Northern Ireland must complete a certain amount of continuing professional development (CPD) each year, which can be done through attending courses, workshops or conferences related to surveying.

In the EU, surveyors can obtain certification through organisations such as the European Federation of National Surveying Associations (FIG). FIG offers a range of professional qualifications and training courses for surveyors which can help them develop their skills and demonstrate their expertise to clients. By obtaining certification from organisations such as FIG, surveyors in the EU can differentiate themselves in the marketplace and demonstrate their commitment to their profession.

Conclusion

Ongoing training for surveying equipment users is crucial in ensuring accuracy, efficiency and safety in the workplace. While some companies may be hesitant to invest in training due to the cost, the benefits of improved performance and cost savings outweigh the initial investment. Certification is also essential for surveying equipment users, and ongoing training can help maintain certification requirements. It is vital that companies prioritise ongoing training for their surveying equipment users to stay up-to-date. Ultimately, investing in upskilling will lead to better outcomes for both the company and its employees.

Frequently our technical support staff get queries from customers about loading drawings to their tablet or datalogger for setting out. Or the site engineer has arrived on site after loading a drawing and it isn't in the right place or the building line or feature that he wants to set out is not displayed or is in a block or has some other problem. The main issue usually is understanding exactly what is required in a drawing before you can go and set out.

Why you need to prepare drawings before staking out?

You can’t upload every drawing to a Total Station tablet or GNSS rover and go and stake out with it. Prior to uploading to the data logger, the drawing must be prepared. There are two reasons for this:

1. Drawings prepared on the PC are using different software to the software on the data logger. Points, lines, objects are handled different in the different software packages. To exchange between one software package and another you need to save the file as a Drawing eXchange Format – a DXF file
2. Dataloggers have significantly less processing and display power than a PC, so the drawing size needs to be less than that on the PC. (See no. 7 below)

What are minimum requirements for a drawing file?

The following details the minimum requirements that a drawing file will need before you upload it to the datalogger for setting out.

1. Drawing should be in meters, not millimeters.
2. Drawing should be layered, with Survey, Contours, Piles, Buildings, Roads, Footpaths, Foul, Storm, Roads, Greenery, Utilities, Boundaries, Walls, etc., etc. all on separate layers.
3. Remove all the following from the drawing:
   • Legends, title boxes, drawing surrounds, explanatory text
   • All hatching
   • House or building internal fittings
   • Unnecessary block, e.g., cars, road gullies, trees, road marking symbols, etc.
4. Explode all objects, including nested objects.
5. Remove complex line styles. Lines should be simple lines or polylines.
6. Purge all unnecessary layers & blocks.
7. The DXF (not DWG) file size should be less than.
   • 1Mb for handheld data loggers (generally 3.5” screen)
   • 10Mb for tablet data loggers 
8. The file must be:
   • For X-PAD software on the data logger any DXF or DWG version.
   • For FieldGenius on the data logger software DXF must be R12/LT2 DXF
9. If there is a lot of detail in the drawing when importing to X-PAD, turn off Object Vertices, as this will create points at every line intersection and end point and make the screen refresh slow.

What if you’re setting out with GNSS rover?

The additional ESSENTIAL requirement for setting out with the GNSS rover is that a drawing must be correctly georeferenced. i.e., coordinates of any point on the drawing must be in either Ireland ITM or Irish Grid and must match its physical position on the ground.

• You can check this in AutoCAD by doing ID POINT on any point – see approximate position in these figures:

• And additionally by checking the actual position of the site boundaries against the drawing (stake out the boundaries).

Ready to start staking out?

Once you follow all the above steps, you can export your drawing to tablet or data logger and rest assured that all the required points will show where they’re supposed to. The file is now a proper size for your data logger, so it won’t freeze on you either.

RTK Corrections are the ‘magic’ behind the high accuracy of surveying grade GNSS rovers. The corrections help to remove the errors caused by the (put the description from septentrio article here - evernote).

RTK Corrections can be produced by the single GNSS Base Station or by the sophisticated software, which calculates the corrections based on the readings of the network of the GNSS Reference Stations.

Calculating corrections

The technique of calculating the corrections involves the measurement of the satellite signal to remove the majority of GNSS type errors.

The calculation process consists of four phases: acquisition (Single or Autonomous), differential positioning (DGNSS), ambiguity ‘Float’ mode and ambiguity ‘Fixed’ mode

This alignment process goes through three phases: acquisition, ambiguity ‘Float’ mode and ambiguity ‘Fixed’ mode. Accuracy in Float mode is around 0.75-0.2 m and in Fixed mode it is 0.01-0.02 m. It is important to point out that accuracy is not the same as what you see in the standard deviation field in your software.

Operators

There are four operators available on the Irish market. They use different infrastructure of the reference stations network around the country.

Hitechniques is a distributor of correction services from VRSNow Trimble. As the largest GNSS rovers hire operator in Ireland we’ve been able to find that VRSNow gives the most reliable corrections with the highest rate of availability. The coverage of the correction service is also the widest. Especially in the far west of the country where other networks fail VRSNow is still giving reliable corrections allowing the rover to reach fix position.

Why do you need the Internet to access RTK corrections?

The RTK corrections can be delivered to the rover in different ways. In very remote areas (no, I’m not talking about Donegal) of the globe professionals use UHF modems (radio transmission, like Walkie-Talkie) for this purpose. They need to set up the base station within the range of the radio connection. Costs of using this kind of set up are much higher than using the RTK corrections produced by the network of reference stations streamed through the Internet. The Network Rovers (the professional name of the rovers using the network RTK corrections from the internet) have different possibilities to get the corrections as well.

Rover receivers like Zenith40 or Zenith60 Pro can use internal cellular modems to connect to the internet and get the necessary data. In Zenith16 rover receiver, it is necessary to use the internet connection delivered by the logger. Some of the more exotic rovers use LoRa connection as well, but it is not widely used.

How to connect your rover to the Internet?

There are so many different brands available on the market at this moment, that one could have a problem with choosing the right one. When it comes to the connectivity and the corrections there is important to have as many options as possible. This would give a piece of mind in a difficult Irish rural environment where the mobile reception is of poor quality.

The mobile internet can be delivered by:

• Cellular modem inside the rover receiver (for example GeoMax Zenith35Pro, Zenith40)
• Cellular modem in the tablet / data logger (Juniper Mesa3 Android, Samsung SM-T395 ActiveTab 2)
• WiFi connection in the tablet / data logger (Juniper Mesa3 Android, Samsung SM-T395 ActiveTab 2)

The field software like Microsurvey FieldGenius and GeoMax X-PAD, both allow the use of the internet connection from the tablet / data logger or from the rover. This allows to further reduce costs of the equipment by choosing, for example Zenith16 which doesn’t have cellular modem but can easily download the corrections through WiFi or internal tablet mobile internet connection.

Choosing the right mobile internet provider is also important. Hitechniques offers MOS2 SIM Cards (Multi-operator mobile internet provider) which can connect with every available network infrastructure in Ireland. The MOS2 service is fully supported by Hitechniques. Any other provider SIM Card can be used as well. Important details which have to be obtained from the provider are: APN server name, APN username and password.

In the next article we will discuss some of the important features in data loggers and what’s hot at the moment.

We’ve been talking about the GNSS rovers a lot. We all know how to use them (if you don’t we have great training courses to get you started), and how accurate they are.

But what’s inside that flat head at the top of the pogo? How does it work and why sometimes it doesn’t give us the results we’re expecting?

Modern and good looking small heads on the top of the poles held by surveyors and construction engineers are very sophisticated electronic devices packed with quite a lot of space and digital technology.

How is a GNSS rover designed?

Measurement engine

The first and the most important module in the GNSS rover is the measurement engine.

All GeoMax rover receivers in example are using the latest technology from Novatel as the measurement engines.

This small yet powerful electronic device is the heart of the rover receiver and is responsible for receiving the analog signals from the antenna module. Measurement engine not only detects the radio frequency analog signals from the satellites but also processes them by decoding the messages carried by the signals. It also calculates the distance between the rover and the satellites. Knowing the position of and the distance to the satellites in space, the engine calculates the position of the rover by calculating the resection. This calculated position is still a raw position with accuracy which can be achieved by the modern smartphones. Of course reliability is much higher in case of surveying GNSS rovers. But the story of calculating the position is only half of the way at this point.

The raw initial position is sent to the supplier of the RTK corrections server and the server sends back the corrections, which are applied by the measurement engine to the position. Then the NMEA stream produced by the rover receiver gives an accurate position down to the milimeters.

Read more about RTK corrections in this article >> 

Cellular modems

Here we are getting to the point where we can meet another module of our small “flying saucer” at the top of the pole: cellular modems.

These small devices are the source of access to the internet which is required to upload the position to the server and download the corrections from it.

It is worth mentioning that modern rover receivers (like GeoMax Zenith16) can work with the internet connection delivered by the handheld computer (tablet or data logger) and they do not need the cellular modem inside.

Corrections can be provided by the UHF modems as well. These types of modems can be used in remote areas to receive the corrections, however there has to be a transmitter of the corrections in close proximity (base).

Zenith35Pro GNSS receiver in standard configuration can be used either as a rover or a base as it has the UHF modem installed.

Antenna module

So we’ve been through the measurement engine, cellular modem and now it is time to mention the other parts of the rover receiver. They are also very important as they provide the external communication and also integrate all the modules together.

Antenna module is responsible for receiving the radio frequency signals from the satellites and is located just under the top cover of the rover receiver. It’s a precisely designed element with highest radio frequency sensitivity, allowing it to receive very weak satellite signals.

Communication module

The communication module is responsible for physical (wire) or remote (wireless) connection of the accessories with the rover receiver. Modern devices (like Zenith35 Pro) have Bluetooth, WiFi, USB and Serial communication allowed. These ports allow the rover receiver to connect to the field computer (data logger, laptop, tablet) as well as update the internal firmware of particular modules.

Main module

The last part is the main module which connects all of the peripherals together, supplies power and digital memory for the modules, delivers physical communication via keyboard panel and sometimes indicators (different colour lamps) or even LCD display.

That’s all when it comes to how the rover receiver is built. We can talk more about things like robustness or waterproofness but to be honest all of the rover receivers available on the market today are built to last and considering the fast pace of development of the satellite precise positioning before they got broken they will be out of date in terms of the used standards.
