Main Characteristics to Consider When Picking an GNSS Receiver
What an RTK GNSS receiver does is to take care of all the positioning data, and does so by using the signals received from all the available satellites. GNSS receivers take care of the positioning part, but you will still need something for correction data to improve the accuracy. This is where suitable software comes into play as it processes the collected data. Just positioning won’t do you any good.
Picking the right kind of GNSS receiver will help you get more accurate results, and in most cases, you won’t even need to go for the most expensive one. Simply think about getting the one that satisfies your needs.
A tilt sensor has to be the best possible additional tool to help GPS surveying. Back in the day, with the older models, we had to make sure to keep the surveying pole level at all times. Now, the tilt function allows us to keep an angle while still being able to measure the point.
Tilt Sensor
However, the angle plays a massive role in how far you can actually tilt the sensor. Some models have a sensor that goes up to 30 degrees. But there are advanced models that come with an IMU sensor, which basically allows you to measure at greater angles.
Accuracy
Pick your equipment based on the type of work you are doing and the level of accuracy required. Depending on the type of project, you may require anywhere from sub-meter for general mapping tasks to centimeter-level for high-precision work.
RTK rovers with centimeter-level accuracy are crucial for critical applications such as cadastral surveying and large-scale construction projects, in which case even a small fraction can make a huge difference.
On the other hand, sub-meter accuracy (or decimeter-level accuracy) is still more than capable of delivering good results. But they serve the purpose of environmental monitoring and GIS tasks, where some deviations are not going to have a great impact on the overall measurements.
GNSS Constellations
GNNS receivers with access to multiple satellite constellation systems have the capacity to perform much better compared to those that only have GPS. Be sure to pick a device that covers them all, and has access to GPS Glonass Galileo BeiDou QZSS SBAS IRNSS, and more.
Also, a GNSS receiver with at least 250 to 400 channels is more than okay. More than that would be too much, but be sure to avoid those with less than 200.
Environment
As a surveyor, you are going to be doing your work in various types of conditions. This means that you need to have equipment at hand that can withstand harsh environments or be able to work even in low signal areas.
There are some situations where you will be working in heavy rain or where conditions may cause high dust clouds. In order for your equipment to work properly in those situations, you have to make sure that it has a high level of resistance.
Also, in those harsh terrains, your equipment might fall and get damaged. In order to avoid those situations, pick those that are impact-resistant. For instance, those with an IP67 protection offer complete dust protection and water immersion resistance up to 1 meter, while IP68 guarantees protection even from submergence.
Integration
Be sure that the tools you are using are compatible with the software that you have. This will allow for seamless data collection and will enable you to read the data faster.
The rover that you are using should be able to communicate with the data collectors and that way convey the gathered information seamlessly. To avoid any technical issues, you have to make sure well in advance that all the components are compatible.
This may depend on the manufacturer, and there are many situations where the software does not match the hardware. To avoid problems in the field, it is better to test out everything at home before actually venturing out in the field and getting faulty results or no results at all.
Internet Connectivity
Internet connectivity becomes a vital part when doing GPS surveys. RTK correction is offered via the internet, and without it, you are not going to be able to do much. You can still set up your own base, but that will incur more costs and make the entire process a lot more difficult.
Make sure to check for the mobile data band that is available. The higher the better, of course. We would also recommend that you pick at least 4G or higher. If they plan to stop using 2G and 3G like the rumors say, you won’t need to upgrade your equipment, and you will also be able to work for longer.
Ease of use
Consider the user-friendliness of a device. Pick those that are easier to use or are within your abilities. Some pieces of equipment may require additional training, so if you don’t have it, you should avoid those tools.
Also, remember that the equipment you are going to be using is as good as your understanding of it. Consider additional learning and training if you truly want to use advanced pieces of equipment. Sometimes, simply joining forums or discussions on the internet may be enough for you to get additional knowledge.
Future Proofing
Another good piece of advice is future-proofing your equipment. Since there are updates to both software and hardware parts of machines, try to pick those that may be easily updated in the future. This one is a bit hard, considering that it is almost impossible to predict future trends. But if you stay up to date with the latest news and advancements in the surveying field, you might be able to determine correctly which piece of equipment to choose.
Budget
Your budget may also shape your final decision when purchasing RTK GPS equipment. Even if you have the funds to get a really expensive and advanced machine, you should hold back and determine if you really need it. Consider the work you are doing, especially if you are a weekend surveyor.
If the scope of work you are doing is not as high, and you may end up doing it only from time to time, a handheld GPS device might even be enough for you. These are incredibly cheap and have the capacity to work incredibly well.
But if you are doing this kind of work professionally and really need equipment that is both durable and accurate, then it is more than okay to spend big. The money you invest in it will soon prove to be worthwhile, as you can do more with it, it will last you longer, and you also get more quality results with it.
FAQ
Consider a few FAQs for the end.
What kind of GPS do surveyors use?
Most survey-grade receivers use two types of GPS frequencies, L1 and L2.
How to use RTK in land surveying?
One unit is positioned at a fixed location with specific coordinates and is referred to as the base station. It employs a high-frequency radio to send its raw data to the second unit, called the rover. The rover then utilizes both sets of observations to calculate its position in relation to the base station in real time.
Which is the most accurate RTK GPS?
It is Point One Polaris RTK Network, which uses signals from GPS, Galileo, GLONASS, and BeiDou satellite constellations, helping to enhance by over 100x for a precise centimeter-level positioning with a 5-second correction time.
What is RTK GPS surveying?
Real-time kinematic positioning (RTK) is a surveying technique used to rectify typical errors found in modern satellite navigation systems (GNSS).
