GPS Equipment

GPS stands for “Global Positioning System,” and it uses signals coming from satellites to pinpoint a specific location. It can also provide data about the speed and time synchronization for different forms of travel. This can be an advantage for land surveyors, because it allows them to get what they need almost instantaneously. As long as the instrument has a clear view of the sky to receive the signals coming from satellites, GPS land surveying can give you the highest degree of accuracy and can be much faster than more traditional surveying methods.

Every piece of GPS for equipment is used for different purposes, but there are three methods of GPS measurement:

• Static GPS Baseline— This method is used to find the coordinates for specific survey points by recording GPS observations over both known and unknown locations for at least 20 minutes. Then, the data is processed so the coordinates can be determined within a 5mm accuracy.
• Real-Time Kinematic (RTK) Observations— One receiver stays open over a known point (called the “base station”), while another receiver moves between different positions (called the “rover station”). By using a radio link, the position of the rover station can be calculated in a few seconds. And as long as it’s within 10km of the base station, it can give you a level of accuracy that’s similar to the baseline method.
• Continuously Operating Reference Stations (CORS)— A survey grade GPS receiver is installed at a specific location as a starting point for GPS measurements in that area. GPS survey equipment can then be used to collect data while combining it with the CORS data to accurately calculate different positions.

Certain instruments are needed for GPS land surveying, which can include but may not be limited to:

• GPS Receivers— These devices are needed to receive signals from GPS satellites, so you can make the calculations you need. They also come with a variety of optional features (such as multiple band channels, built-in Bluetooth, Wi-Fi technology, and OLED displays).
• GPS Rover Rods— These instruments can be used to extend the rover’s range. They can be made from a number of durable materials and can come in different lengths.
• GPS Poles— They’re used to mount GPS survey equipment. They’re lightweight, durable, and can come in different lengths.
• GPS Bipods/Tripods— Different GPS equipment can be mounted on them, so more stability can be achieved. They can also be adjusted to different lengths.
• GPS Antennae— They make it possible for GPS systems to receive signals from satellites. Many devices come with internal antennae, but you can use these devices to get more signal strength.
• Total Stations— They combine the functions of an electronic theodolite with an electronic distance meter (EDM) device, and they come with software that you can run on your computer. Total stations can be used to determine the coordinates of different survey points by measuring angles and distances, but they can also use GPS technology to get more precise results.

The cost of GPS for equipment can vary. But if you want to get the best value for your money, be sure to look at what we have in stock.

There are places where you can rent GPS equipment you can use for surveying. And in some cases, this option may be more economical. You may only need it for a specific project, or you may want to try out the equipment before you decide to buy it.

If you’re looking for GPS survey equipment that you can use on your next project, Engineer Supply has tools from some of the best manufacturers on the market. We offer a variety of GPS and GNSS devices, which include but may not be limited to:

• GPS pole transporters.
• GNSS rods.
• GPS tripods.
• GPS bipods.
• GPS prism poles.
• GPS rover rods.

We also carry a variety of GPS-related accessories (such as bags and cases). Feel free to look at what we have in stock, so you can find a product that will meet your specific needs.
