WheresTheJam.com is a free, community-focused GPS interference monitoring platform designed to help pilots, aviation professionals, researchers, journalists, and the public better understand where GPS jamming events are occurring.

Our platform aggregates daily data and heatmaps from the Stanford GPS Laboratory's publicly available interference site and presents it through an easy-to-use interactive map, allowing users to visualize interference hotspots over time, identify trends, and monitor areas where GPS-dependent systems may be impacted.

GPS interference has become an increasingly significant issue for civil aviation, maritime operations, emergency services, critical infrastructure, and everyday users who depend on accurate positioning, navigation, and timing services. WheresTheJam provides a simple way to explore this growing phenomenon and increase awareness of its real-world impacts.

Our Mission

Our mission is to make GPS interference data more accessible, understandable, and actionable by transforming complex technical measurements into intuitive visualizations that can be explored by anyone.

We believe that open access to interference data supports:

• Aviation and transportation safety
• Academic and scientific research
• Public awareness
• Better understanding of global GPS interference trends

Data Sources and Attribution

WheresTheJam aggregates and visualizes GPS interference data made publicly available by the Stanford GPS Laboratory.

We gratefully acknowledge the Stanford GPS Laboratory for collecting, processing, and publishing the underlying data that powers this platform.

The Stanford GPS Laboratory provides this data for non-commercial sharing and adaptation with proper attribution. WheresTheJam does not claim ownership of the underlying Stanford data and serves as an independent visualization and monitoring platform built upon their publicly available research products.

Disclaimer

WheresTheJam is an informational and educational tool. The platform does not provide real-time operational warnings, flight safety advisories, or navigation guidance. Users should always rely on official aviation authorities, government agencies, and approved operational sources for safety-critical decision-making.

While we strive to present data accurately, GPS interference conditions can change rapidly and may not be reflected immediately on the map.
