Hi @francisco
I can give you only general recommendations:
Insufficient Number of Satellites: A minimum number of satellites need to be visible to the receiver to calculate a fixed solution. If not enough satellites are visible, the receiver can only provide a float solution
Poor Satellite Geometry: The position of the satellites in relation to each other can affect the accuracy of the positioning solution.Poor geometry can prevent a fixed solution
Obstructions: Physical obstructions like buildings or trees can block the signal from satellites, making it difficult to maintain a fixed solution. It's important to have a clear view of the sky
Tropospheric Delay: The troposphere can cause delays in the GNSS signals, which varies with height above sea level, weather conditions, and satellite elevation angle. This can affect the accuracy of the RTK solution
Internet Quality: A poor Internet between the base station and the rover can prevent a fixed solution.A stable and fast connection is crucial for RTK corrections
To improve the chances of getting a fixed RTK solution, ensure the GNSS receiver has a good sky view, a stable internet connection for RTK corrections, and is not hindered by physical obstructions. If you're in an area with poor visibility, try obtaining a fix in a more open area first and then move slowly to the desired location
