5.5.3. Calibration of GPS Equipment

Try these first

1. 1.

   What is a baseline check?

   Hint

   Think about what a reference point might be.

2. 2.

   Why is antenna height verification important?

   Hint

   Consider how measurements are made from the ground.

3. 3.

   What is the primary purpose of a baseline check in GPS calibration?

   • To update the firmware
   • To verify GPS measurements
   • To adjust for environmental conditions

   Hint

   Remember why we check measurements initially.

4. 4.

   True or False: Firmware updates are optional for GPS receivers.

   • True
   • False

   Hint

   Consider how software updates work in other devices.

5. 5.

   A surveyor finds that in repeated baseline checks, their GPS receiver consistently reports a distance that is 2 meters shorter than expected. Analyze the potential reasons for this discrepancy and suggest remediation steps.

   Hint

   Consider each component's role in the measurement process.

6. 6.

   After updating the GPS receiver's firmware, measurements seem erratic. Propose a troubleshooting approach to resolve these issues, considering environmental conditions and known calibration methods.

   Hint

   Think about how changes can affect device performance.
