You're facing GPS signal issues during field data collection. How can you troubleshoot them with GIS? (original) (raw)

When you're dealing with GPS signal issues during field data collection, leveraging Geographic Information Systems (GIS) can offer practical solutions. Here’s what you can do:

• Check satellite visibility: Use GIS tools to identify obstructions like buildings or trees that might be blocking satellite signals.

• Update GPS firmware: Ensure your device has the latest software updates to improve signal reception and accuracy.

• Utilize differential GPS (DGPS): This technique enhances positional accuracy by correcting errors in real-time using a network of fixed ground-based reference stations.
