How do I improve GPS accuracy in challenging environments?

To enhance GPS performance:

1. Connect an external GPS receiver (Bluetooth or USB)
2. Use GPS averaging for stationary locations
3. Enable AGPS (Assisted GPS) if available
4. Minimize electromagnetic interference from other equipment
5. Update device drivers and firmware
6. Position device with clear sky view when possible
7. Use terrain matching features if available
   Consider implementing RTK (Real-Time Kinematic) GPS solutions for mission-critical applications requiring centimeter-level accuracy.
