Calian antenna test advances TrustPoint’s GPS-independent navigation hardware

Calian’s C-band antenna moved through live orbital signal testing, with TrustPoint reporting reliable acquisition and reception. A combined L1/L5 and C-band antenna remains in development.

Infrastructure and utility operators could gain another navigation and timing option when GPS cannot be relied on. For local operations and field-work planning, this is a hardware milestone to monitor—not yet evidence of a deployable service with established coverage and performance.

Calian has tested a commercially manufacturable C-band GNSS antenna against TrustPoint’s live orbital broadcast, with successful signal acquisition and sustained reception reported across multiple tests. This advances the receiving hardware needed for TrustPoint’s GPS-independent positioning, navigation and timing system; it does not establish that a complete operational service is available. The companies are also developing an antenna combining L1/L5 and C-band reception. For local public works, utilities and infrastructure teams, the relevance is a potential additional navigation and timing option where GPS availability is unreliable. The immediate takeaway is to track service readiness rather than assume field deployment is ready: the article provides no antenna pricing, positioning accuracy or local coverage details. TrustPoint says it is establishing a four-satellite, four-ground-station system under a U.S. Space Force contract, targeting live trilateration and initial operational services within 12 months.
