Comprehensive solutions for improving GPS satellite signal quality
Common physical obstacles that can affect GPS signal quality:
When possible, move to a more open area with clear sky visibility above 15° elevation mask. If working in challenging environments, plan surveys during optimal satellite geometry windows.
Always inspect antenna cables for signs of wear or damage before each survey. Damaged cables can significantly degrade signal quality.
Increase elevation mask to exclude low-quality satellites. Start at 15° and adjust as needed.
Set minimum SNR threshold to 40 dB-Hz to ensure only strong signals are used.
Enable additional satellite systems (GLONASS, Galileo) to improve coverage.
Consider accepting float solutions when fixed solutions are unavailable.
Evaluate surroundings for obstructions
Inspect antenna and connections
Monitor number of visible satellites and PDOP
Modify elevation mask and SNR thresholds
