Global Navigation Satellite Systems (GNSS) signals are vulnerable to jamming and there is now extensive denial of service in part of Europe. To provide resilience, alternative Position Navigation Timing (PNT) solutions are needed separated in frequency from the L-band GNSS signals. The PNT as a Service (PNTaaS) solution developed by NAVSYS allows existing broadband Satellite Communication (SATCOM) satellites, operating in C-band, Ku-band or Ka-band, to be used for PNT as signals of opportunity (SoOP).

In this paper, the open architecture PNTaaS solution is described. The PNTaaS Cloud Platform provides data services that publish what SATCOM satellite signals are available to be used as SoOP. Users can then subscribe to the PNTaaS services to receive data content snapshots of the broadband SoOP along with the timing and satellite location data needed to use these signals for PNT. By capturing a SoOP signal snapshot at the same time as the published PNTaaS data, PNT observations can be made by processing the received PNTaaS data using a simple Software Defined Radio (SDR).

NAVSYS has been operating the PNTaaS Cloud in the United States and recently deployed PNTaaS infrastructure to Europe on a trial basis for testing with selected partners. In this paper we describe the operation of the PNTaaS components, test results for timing applications using selected SoOP and plans for further deployment of the service and opportunities for partners to leverage this capability.
