Warm Start

In a warm-start condition the receiver has been powered down for at least one hour but has stored a
current almanac, an initial position and time in memory.
When connected to an external back-up power source (battery back-up), the NAVIOR-24S
GPS/GLONASS receiver retains the almanac, approximate position, and time to aid in satellite
acquisition and reduce the time to first fix. When an external back-up battery is not used, the BINR
protocol allows the almanac, an initial position, and time to be uploaded to the receiver via the
serial port, to initiate a warm start.
During a warm start, the NAVIOR-24S GPS/GLONASS receiver identifies the satellites which are
expected to be in view, given the system almanac, the initial position and the approximate time. The
receiver calculates the elevation and expected Doppler shift for each satellite in this expected set
and directs the eight tracking channels in a parallel search for these satellites.
The warm start time to first fix, when the receiver has been powered down for more than 60
minutes (i.e. the ephemeris data is old), is usually less than 50 seconds.
