General Description Delin Comm DM1616 is a
complete GPS engine module that features super sensitivity, ultra
low power and small form factor.it with superior and performance
even in urban can-yon and dense foliage environment.
This module supports hybrid ephemeris prediction to achieve
faster cold start. One is self-generated ephemeris prediction
(called EASY) that is no need of both network assistance and host
CPU's intervention.This is valid for up to 3 days and updates
automatically from time to time when GPS module is powered
on and satellites are available. The other is server-generated
ephemeris prediction (called EPO) that gets from an internet
server. This is valid for up to 14 days. Both ephemeris predictions
are stored in the on-board flash memory and perform a cold
start time less than 15 seconds.FeaturesBuild on high performance,
