Proven Performance
NextNav has conducted extensive testing of its system in a variety of common environments so you can see how our system performs in the real world. As we work to continually improve our system and extend our testing, check back for updated results.
Pervasive X-Y Accuracy across an Entire Market
NextNav’s first market, in Santa Clara County, California, presents a mix of urban and suburban terrain that is representative of many U.S. metro areas. Our system delivers 20m or better position accuracy 50% of the time and 44m or better 90% of the time.

The Only System With Demonstrated Height Performance
By using real-time, proximity-based pressure differential measurements, NextNav has demonstrated vertical accuracy of 1 – 2m. For devices equipped with an optional, low-cost pressure sensor, this capability could save valuable time in an emergency response, in a social networking situation or provide critical context for marketing purposes.

Extremely Rapid Time to First Fix
The NextNav signal is very strong compared to a GPS signal, but similar in many other respects. GPS hardware optimized for pulling a very faint signal out of natural background noise can decode the stronger NextNav signal much more rapidly, resulting in a “cold start” TTFF of approximately 5 seconds. This is important for consumer applications, and critical for emergency response.
Time to First Fix Comparisons: How NextNav compares.
Very High System Yield—95% +
NextNav’s system is designed to provide pervasive coverage across an entire market, and has a yield of over 95% in its network footprint. GPS is often available less than 50% of the time in these areas, and is virtually unavailable indoors.
