A team anticipated potential GPS issues in dense tree cover in an Aforestry project. They used GIS to pre-map signal strength based on topography and vegetation density, allowing them to plan alternative data collection methods in weak signal areas. When signal loss occurred, they switched to using pre-downloaded basemaps and collected data manually, which was later georeferenced in the office using GIS. This way we can also effectively troubleshoot and minimize the impact of GPS signal loss by combining GIS-based planning with adaptive field strategies.

Alem do que já foi citado, verifique as configurações dos equipamentos. Entre nos site do fabricante do seu equipamento e verifique se não há informação sobre falhas na comunicação.

When GPS signal loss occurs, first ensure that your equipment is properly connected and configured. Verify that settings are correct and that all cables and antennas are secure.If GPS continues to be unreliable, use alternative positioning methods like triangulation from known points or referencing high-resolution GIS maps with identifiable landmarks.Consult GIS overlays for environmental factors such as dense tree cover, buildings, or electromagnetic interference that might be affecting the signal. These insights can help pinpoint areas where GPS signal is likely to degrade, allowing you to plan alternative routes or strategies.
