The following is a partial transcript of a talk given to the National PNT Advisory Board Executive Committee (PNTAB ExCom) on December 9, 2021. It connects GNSS signal authentication, by both Galileo’s OSNMA and the proposed GPS Chimera signal, with developing PNT capabilities in 5G telecom technology, and further, with software-defined radio (SDR) capabilities aboard some GNSS satellites that could place GPS in the second tier.

When a wireless 911 call comes in from a multi-story building, it can be difficult to pinpoint exactly where the caller is—wasting valuable time. NextNav has developed a solution with z-axis capabilities, Pinnacle 911, that addresses this GPS shortcoming, and recently entered into an agreement with a top wireless carrier to leverage it for enhanced 911 (E911).

The smartphone and its various everyday apps link us to GPS, Wi-Fi networks, Bluetooth LTE, audio and cell tower proximity that help us find out where we are and tell us how to get to where we need to go, down to precise latitudes, longitudes and altitudes, accurate to within a few yards. So who should have access to this information?

NextNav and Qualcomm Technologies, Inc. now collaborate to enable NextNav’s Pinnacle 911 z-axis software and network-based services for use with the Qualcomm Location Suite. This facilitates integration of vertical location into existing carrier infrastructure for emergency 911 purposes by device and original equipment manufacturer (OEM) vendors.

NextNav and Satelles, Inc. have partnered on an alternative positioning, navigation, and timing (PNT) testbed in the San Francisco Bay Area. Designed and managed by NextNav with a timing source from Satelles, the testbed creates scenarios and conditions to rigorously test the precision and resilience of alternative PNT solutions
