6.1 Initialization
As soon as the initial self-test ends, the CR-100 automatically starts the
satellite acquisition and tracking. It normally takes approximately 45 seconds
to obtain a position fix and about 38 seconds if the ephemeris data is known.
After the position fix is calculated, the information about valid position, velocity
and time will be transmitted to the output channel.
The CR-100 utilizes the initial data such as last stored position, date, time
and satellite orbital data to maximize acquisition performance. If there exists a
significant inaccuracy of the initial data, or an obsolete orbital data, it may take
more time to obtain a navigation solution. The CR-100 Auto-locate feature can
automatically determine a navigation solution without any intervention from the
host system. However, the acquisition performance of the CR-100 can be
improved for initializing the host system in the following situations:
1) Moving farther than 500 kilometers.
2)
Failure of data storage due to an inactive internal memory battery.
6.2 Navigation & Software interface
After the acquisition process is complete, the CR-100 sends valid
navigation information over output channels. These data include:
