Services (RTCM Recommended Standards For Differential Navstar GPS Service, Version 2.1, RTCM Special Committee No.104). As soon as the initial self-test is complete, the GR-90 begins the process of satellite acquisition and tracking automatically. Under normal circumstances, it takes approximately 48 seconds to achieve a position fix, 38 seconds if ephemeris data is known.
