How to Get Your GPS Working After a Long Break: Tips and Troubleshooting

Are you struggling to get your GPS working after a long period of inactivity? Whether you have an old device like the Trimble Explorer, or a new one, getting it to work smoothly can be a challenge. This guide will help you troubleshoot common issues and ensure your GPS is operating to its best potential.

Troubleshooting an Older GPS Device

Have you recently experienced issues with your Trimble Explorer or a similar device from the early 2000s? It's common for older GPS units to take a while to get a first fix, especially if they haven't been used for a while. Here are some steps to help you diagnose and improve your device's performance:

Check Battery Contacts: Ensure the battery contacts are clean. A gentle cleaning with an emery cloth or a pencil eraser can make a significant difference. New Batteries: Fresh batteries can greatly increase the speed of the first fix. Test with a fully charged set if possible. Clear Sky View: Place the GPS in an open area with a clear view of the sky. Trees, buildings, or objects can block the signal, significantly increasing the first fix time. Configuration Settings: Some GPS units allow you to choose an approximate location to speed up the process. This can be a useful setting if you know roughly where you are. Time Accuracy: Ensure your GPS has the correct time. If the date or time is incorrect, it can take a long time to get a fix. If there's a backup battery that has died, it may need to reset to the correct time.

GPS Basics and Availability

Understanding the basics of GPS can help you troubleshoot further:

24/7 Broadcast: GPS is always broadcasting, 24/7. It doesn't require a subscription and isn't affected by weather conditions, unless heavily obscured by trees or buildings. Global Satellite Network: There are 24 satellites in the global GPS network, plus about 3 spares. This extensive network ensures constant availability, and there should never be a temporary outage. First Fix: If your GPS unit has been turned off for a long time, the stored ephemeris information may be outdated. Some units have a configuration option to help speed up the process if you have an approximate location.

Common Issues and Solutions

Here are some common issues you might encounter with your GPS and corresponding solutions:

1. Device Doesn't Power Up

Check Batteries: Ensure you have fresh batteries installed. If the unit still doesn't power up, it's likely a hardware issue and may require professional repair or refurbishment. Reset the Unit: If the unit powers up but then freezes, try a reset. The process varies by manufacturer, but online resources typically provide guidance and videos.

2. Device Won't Process Signal

Software Update: Ensure your unit's software is fully up to date. This can sometimes resolve issues with signal processing. Reroute the Device: If a reset fails, consider moving the GPS to a different location with a better view of the sky. Sometimes, simply moving the device can resolve the issue.

Conclusion

GPS devices are a reliable tool for navigation, but they can sometimes require troubleshooting. By following these tips and solutions, you can improve the performance of your GPS and get it working properly. Remember, regular maintenance and proper use can ensure your GPS remains a reliable companion for all your outdoor adventures.
