Quick Answer
To use a compass with a GPS device, start by verifying the GPS accuracy and setting a bearing or route on the device. Use the compass to confirm the direction of travel and adjust as needed. This ensures accurate navigation, especially in areas with weak GPS signals.
Setting Up a Reliable Navigation System
When combining a compass with a GPS device, it’s essential to set up a reliable navigation system. Begin by calibrating your compass in an open area with minimal interference. Hold the compass level and steady, and allow it to stabilize before taking a bearing. Next, enter your destination coordinates into the GPS device and set it to provide a bearing or route. This will give you a clear direction of travel.
Confirming Direction of Travel
To confirm the direction of travel, hold the compass level and align the magnetic needle with the direction-of-travel arrow. Take a bearing by moving the compass slowly to match the GPS direction of travel. If the bearings don’t align, recheck the GPS settings and compass calibration. In areas with weak GPS signals, use the compass to adjust your direction of travel and stay on course.
Maintaining Accurate Navigation
To maintain accurate navigation, regularly check your bearing on the compass and adjust as needed. If you notice a discrepancy between the GPS and compass readings, take corrective action to stay on course. Consider using a secondary GPS device or a paper map as a backup, especially in areas with limited visibility or weak GPS signals.
