One of the most important aspects of RTK GPS and RTK systems in general is understanding how they work. This doesn’t mean understanding the complex mathematical formulas that go on in the software to ensure reliable and consistent communication between base stations and satellites however. It is a much more practical understanding of how to actually begin surveying out in the field.
If you’re wondering how to setup a survey correctly, following these steps can bring you to accurate results and smooth operation.
Select Your Survey Location
The first step in setting up your RTK GPS surveying station is to select your location. You should try and find an established benchmark, but if none are available, a flat area free from obstructions can be used. Ensure there is little to no uneven ground for best results. Good site selection is a critical part of knowing how to setup a survey effectively.
Mount Your Surveying Equipment
Next, set up your tripod and secure it in place. Then, mount your dumpy level, total station or other piece of RTK GPS survey equipment. You will want to use the set screws and bubble level to ensure it is level with the ground and ready for calibration.
Calibrate and Focus Your Viewfinder
Calibrate and focus your viewfinder using the adjustable controls. You want to ensure the picture is clear and the crosshairs are aligned before use. This is also the stage where you should connect the system to power and ensure there are no software issues. Some devices also include digital calibration tools, simplifying the process.
Take Measurements
At this stage, all that is left to do is take measurements. Once your operation is complete, make sure you stow the equipment in its proper travel location to prevent damage.
How Does Surveying Equipment Work?
Surveying equipment combines precise optical or electronic measurements with satellite or base-station corrections. RTK GPS units, for example, calculate position by receiving signals from multiple satellites and applying corrections from a base station. Total stations measure angles and distances and are used for the creation of accurate maps, layouts, and 3D models.
Using surveying equipment begins with proper setup, calibration, and understanding of the task at hand. Follow these key steps for reaching the best results:
Regularly confirm that the equipment remains correctly calibrated throughout the survey.
Set up your tripod securely and make sure the equipment is perfectly leveled using built-in bubble levels or digital tools.
Power on and verify software systems. The device has to be fully operational, all corrections or GNSS connections active, and the firmware up to date.
Orient the instrument using known benchmarks or control points to establish a reliable starting location.
Capture measurements systematically following your survey plan, and document or log data accurately.
Watch for obstructions, reflective surfaces, and other conditions that may impact precision. Adjust position or technique as needed.
