GPS Glitch Hits US, Errors Up to 33 Feet—Scientists Baffled
TL;DR: The recent GPS anomaly in the US caused position errors up to 33 feet due to an unexplained signal distortion, though the exact cause remains under investigation. Users should rely on offline maps or alternative navigation methods until further notice.
Step-by-Step Instructions for Mitigation
When encountering significant GPS drift, immediate action can improve navigation reliability. Follow these steps to minimize errors during the glitch period.

Step 1: Verify Your Location Manually. Before proceeding, compare your device’s current pin with a physical landmark or known street name. If the discrepancy exceeds 10 feet, assume the GPS is unreliable for precision tasks. Do not trust the blue dot for critical maneuvers like parking or entering narrow alleys.
Step 2: Switch to Offline Maps. If you have pre-downloaded maps, switch your navigation app to offline mode. While offline mode still uses GPS for positioning, it reduces the load on data networks that might be contributing to signal interference. This can sometimes stabilize the connection enough to reduce jitter.
Step 3: Use Visual Landmarks as Primary Guides. Treat GPS coordinates as a rough guide only. Rely on visible street signs, building entrances, and physical barriers. If your device says you are on Main Street but you see Elm Street ahead, trust your eyes. This manual override prevents you from taking wrong turns based on faulty data.
Step 4: Restart Your Device. A simple reboot can clear cached location data that might be corrupted. Turn off your phone, wait for ten seconds, and turn it back on. Allow the device to reacquire satellite signals before re-enabling navigation. This resets the internal compass and GPS modules, potentially clearing temporary glitches.
Step 5: Enable Assisted GPS (A-GPS) if Available. Some devices allow you to toggle A-GPS settings in the developer options or location services menu. A-GPS uses cellular data to help the device find satellites faster. While this doesn’t fix the root cause, it may help the device lock onto stronger signals from nearby base stations, potentially reducing error margins.
Step 6: Avoid Precision-Critical Tasks. If possible, delay activities that require high precision, such as drone flying, surveying, or autonomous driving testing. The 33-foot error margin is acceptable for general driving but dangerous for these specialized applications. Wait for official updates from satellite providers before resuming such tasks.
Step 7: Monitor for Updates. Keep your navigation apps and operating system updated. Developers often release patches to improve signal processing algorithms in response to widespread issues. Check app stores for updates that mention “GPS accuracy” or “navigation improvements” in the release notes.
Pro Tips for Better Accuracy
Clear your phone’s storage if it is full, as this can sometimes slow down location services. Ensure your phone case is not made of metal or thick magnetic materials, which can interfere with the antenna. Finally, keep your phone away from your body when navigating, as human tissue can slightly weaken the signal.
FAQ
Q: Is the GPS glitch dangerous for driving?
A: Generally, no, for standard highway driving. However, it increases the risk of taking wrong turns in complex city centers, so extra caution is advised.
Q: Will my phone battery drain faster during the glitch?
A: Yes, potentially. If the GPS struggles to lock onto a signal, it may work harder to calculate position, leading to increased power consumption.
Q: How long is this glitch expected to last?
A: Currently, there is no confirmed end time. Scientists are still investigating the cause, so users should prepare for a period of reduced accuracy.
