Operational characteristics 2. 1 Initialization As soon as the initial self-test is complete, the GR-213U begins the process of satellite acquisition and tracking automatically. Under normal circumstances, it takes approximately 42 seconds to achieve a position fix, 38 seconds if ephemeris data is known. After a position fix has been calculated, information about valid position, velocity and time is transmitted over the output channel. The GR-213U utilizes initial data, such as last stored position, date, time and satellite orbital data, to achieve maximum acquisition performance. If significant inaccuracy exists in the initial data, or the orbital data is obsolete, it may take more time to achieve a navigation solution. The GR-213U Auto-locate feature is capable of automatically determining a navigation solution without intervention from the host system. However, acquisition performance can be improved as the host system initializes the GR-213U in the following situation: 1) Moving further than 500 kilometers. 2) Failure of data storage due to the inactive internal memory battery. 2. 2 Navigation After the acquisition process is complete, the GR-213U sends valid navigation information over output channels. These data include: 1) 2) 3) 4) 5) Latitude/longitude/altitude Velocity Date/time Error estimates Satellite and receiver status 4 3.
