INTEGRATING STL INTO LOW-SWAP ASSURED POSITION, NAVIGATION, AND TIMING SOLUTIONS FOR MILITARY INFORMATION SYSTEMSSinden, Jon; Perdue, Lisa; Spectracom (International Foundation for Telemetering, 2017-10)Today’s military communications and information dominance systems rely on available and accurate GNSS PNT signals to provide leaders the information required to make timely and effective decisions. The proliferation of GNSS-degrading and denying devices across state and non-state actors puts this critical information overmatch capability in jeopardy. Traditional PNT devices utilize various alternative internal components to maintain holdover of the PNT data during loss of GNSS input but are susceptible to drift over time. This presentation discusses how the Satellite Time and Location (STL) service integrated into low Size, Weight, and Power (SWAP) assured PNT devices can provide critical continuity of operations when GPS is unavailable. Comparison timing testing between a GPS-disciplined oscillator in holdover and STL is presented. Future considerations for STL as an alternative position and navigation signal of opportunity are also discussed.
