Startup TrustPoint Bets Big on C-Band for Next-Gen Navigation

TrustPoint, a startup in its fifth year of operation, is preparing for a soft launch of its C-band positioning, navigation, and timing (PNT) services in 2027. This ambitious project aims to establish a low-Earth-orbit navigation network that can serve as a complement or alternative to existing systems like GPS. The company's timeline is contingent on successful on-orbit demonstrations and receiver integration over the next two years.

The company's CEO, Patrick Shannon, stated that TrustPoint is seeking both military and commercial funding to advance its constellation, which could eventually comprise up to 300 satellites. Early development has been supported by private investment and government contracts, including those from SpaceWERX, which have facilitated current tests involving three operational satellites. Shannon highlighted strong demand from the U.S. government, citing a growing need for GPS alternatives due to increasing jamming incidents.

TrustPoint's distinct approach involves broadcasting navigation signals solely within the C-band spectrum, a higher frequency than the L-band typically used by GPS. This choice is driven by security considerations, as C-band is considered more resistant to jamming and spoofing techniques that target legacy frequencies. While competitors like Xona Space Systems are exploring L-band, TrustPoint maintains that C-band offers superior benefits, supported by customer feedback and the desire to move beyond L-band limitations.
