NextNav Inc.

NextNav Inc. is a leading provider of next-generation 3D Positioning, Navigation, and Timing (PNT) solutions, headquartered in Reston, Virginia, U.S.. The company's core mission is to develop and deploy terrestrial-based geolocation services that complement and provide a resilient backup to satellite-based Global Positioning Systems (GPS), particularly in environments where GPS signals are unreliable, such as indoors or in urban canyons, and vulnerable to jamming or spoofing.

NextNav offers key products and services including Pinnacle, a 3D geolocation platform providing highly accurate vertical (z-axis) location, crucial for applications like Enhanced 911 (E911) and public safety. Its TerraPoiNT system delivers resilient 3D PNT services designed for critical infrastructure and other GPS-reliant systems, ensuring accurate and reliable positioning even in the absence or failure of GPS. The company leverages its extensive licensed low-band spectrum in the 900 MHz band to power its terrestrial network.

Mariam Sorond was appointed CEO in November 2023, succeeding co-founder Ganesh Pattabiraman. In June 2026, NextNav completed the redemption of all outstanding public warrants and 5.00% Senior Secured Convertible Notes, a move aimed at enhancing financial flexibility. The company is actively engaged with the FCC to advance the use of the Lower 900 MHz band for terrestrial PNT services and mobile broadband, and has recently expanded its spectrum holdings in this band. NextNav positions itself as a leader in next-generation 3D PNT solutions, holding the nation's largest license in a spectrum band designated for terrestrial positioning services, vital for national security, public safety, and economic resilience.
