Globalstar Inc. and its partner Echo Ridge LLC have informed the US Department of Transportation (USDOT) that they have developed and can demonstrate a navigation that could be deployed in the event of a failure of the US Government-owned GPS system.

Globalstar and Echo Ridge have told the USDOT that they are prepared to participate in and support a live field demonstration of a stand-alone positioning, navigation, and timing (PNT) capability that can provide accurate and reliable PNT services to backup and/or complement GPS in case of its unavailability or unreliability. The companies have responded to a USDOT Request for Information (RFI) regarding the agency’s plans to find a solution to the possible disruption to the country’s transportation network in the event of problems with GPS. The partners informed the DOT that all the required elements are available now for demonstration of a backup system that provides diversity of frequency, constellation, and signal to the existing GPS system, as well as independent ground and management infrastructure.
