When doing a cold start, the tracker sends its frst positon using the
gps_timeout
value. Afer this
one, the tracker uses systematcally a tmeout of 5 minutes instead of the confgured one (except in
SOS mode), untl it succeeds in having a positon.
To complete a positon, the GPS module expects one of the tto folloting conditons to be achieved.
The
gps_coniergence
tmeout (tme let to the GPS module to compute a more precise
positon) expires.
The
gps_ehpe
value is belot the confgured value. EHPE (Estmated Horizontal Positon
Error) is provided by the GPS component and is expressed in meter.
