RTK GPS has brought great convenience to our survey work. However, RTK GPS keeps displaying "Single", "DGPS" or "Float", and can't get the "Fixed" status, especially when the sun is scorching and therefore the body is exhausted. This is often a really maddening thing. We've collected and sorted out relevant information for this purpose. First of all, we released a solution to the "Single" state. Maybe we'll solve these RTK problems through the next tips.
Why it’s “Single”?
When the RTK displays the "Single" status, it means the RTK receiver doesn't use any differential correction information to calculate the three-dimensional coordinates. If you're using the radio mode, there could even be a haul with the connection or settings of rover.
How to deal with?
- Check whether the bottom station is functioning normally and whether the signal light of the bottom station is flashing and transmitting signals normally. If it blinks normally, attend step 3. If it isn't normal, attend step 2.
- If the bottom station signal flickers abnormally (the signal cannot be transmitted normally), it's getting to be that the bottom station coordinates are abnormal, and smoothly obtain the transmitting coordinates again. You'll also check whether the cable is plugged in, whether the connection line is broken, whether the battery power is simply too low, etc. (external radio mode). Check whether the radio antennas on all sides of the bottom station and rover are plugged in (built-in radio).
- If the signal light of the bottom station is flashing normally (normally transmitting signals), the signal light of the rover doesn't flash. Check whether the air baud and radio channel of the bottom station and therefore the rover are consistent.
- If the signal lights of the bottom station and therefore the rover are both flashing, check the differential telegram format of the rover and thus the bottom station, and set them to a consistent format.
- If there is no problem with the settings, observe and measure the encircling environment again. If the rover is seriously blocked, you'd wish to re-set up the station in an open place.
- Finally, check whether the space between the rover and thus the bottom station is beyond the range set by the instrument.

At the beginning of the article, we need to say sorry to everyone, because in the original plan, we will explain the solution to the host problem during the RTK rover setup process in this article.
During the writing process, it was found that the solution of the RTK rover was basically the same as the solution of the RTK base station in the previous article, so we did not describe the solution of the RTK rover in detail.
I believe that everyone will solve the RTK GPS problem easily after studying the content of the previous article.Additional point:What needs to be reminded here is that in radio mode, the coverage range of the general external radio is less than 20km, and the coverage of the built-in radio is less than 5km.
The specific situation depends on the actual area and terrain.One more tip:If your receiver has an abnormal voice broadcast, you can troubleshoot and solve the problem from the following aspects.In the external radio mode, check whether the external radio antenna is too close to the host and cause interference.
We recommend that the transmitting antenna need to be at least two meters away from the main unit; in the built-in radio mode, check whether an extension pole is used to isolate the base of the tripod and the main unit (the built-in radio antenna cannot be in contact with the metal object on the base or the tripod), Thereby reducing the interference of metal objects on radio transmission.If necessary, you can remove the battery of the main unit, place it on a metal object (to discharge static electricity), then reinstall it and turn it on.That’s all.Learn more about RTK solution: https://www.satlab.com.se/product_category/gnss/
It is important to Install Magellan Content Manager,without a content manager you cannot update Magellan GPS device.Like other GPS devices, Magellan GPS also has its own software that has been released by the company.
This software helps the GPS device while updating the maps.
