Building Resilience with C-Band

"Today’s GNSS disruptions go beyond just losing a fix for a few seconds here or there, or signals dropping out when users drive through a tunnel. Those who rely on GNSS are now regularly con-fronted with persistent and even complete loss of services, a costly and dangerous problem. Th is new reality has shift ed the industry focus to finding diverse, complementary solutions that add resiliency to fight against multipath, spoofing and jam-ming, ultimately enabling a more layered approach to PNT.

TrustPoint is among the companies leading the complementary PNT (CPNT) charge, with the team putting their efforts into signal diversity. From the start, TrustPoint has been a C-band centric company, Founder and CEO Patrick Shannon said, with the focus on developing a dual-use low Earth orbit (LEO) PNT system and C-band service. Low-cost microsatellites will power the service, leveraging commoditized space platforms, rideshare launch services, and patented innovations in navigation signal generation and processing at the RF physical and navigation data layers.

TrustPoint recently launched its third satellite, Time Flies, and successfully established first contact. Th e satellite, which represents the continued evolution of the company’s C-band mission, is substantially smaller than heritage GNSS systems and carries a digitized GNSS payload. It’s a culmination of design work and lessons learned from the two previous satellites—It’s About Time and Time We’ll Tell launched in 2023—and boasts more power, channels and autonomy than its predecessors.
