From monitoring the integrity of the GPS constellation, to situational awareness
for theaters of operation, to the support of critical operations world-wide, the GDGPS System
can assess the performance of the GNSS navigation signals
JPL's network tracks each GNSS satellite with a denseR, global
tracking network that provides extraordinary level of redundancy and the opportunity
for strong majority voting schemes.
Our suite of monitoring tools provides customized alarm thresholds with as
little as 4 seconds time to alarm, graphical and binary user interfaces,
communications protocols, and around-the-clock operations for the most demanding
applications. The GDGPS staff of engineers can tailor a performance monitoring
application for your needs.
