General
Description
The DM1616 is a complete GPS engine module that features super sensitivity, ultra low power and small
form factor. The GPS signal is applied to the antenna input of module, and a complete serial data message
with position, velocity and time
information is presented at the serial interface with
NMEA
protocol or
custom
protocol .
Its
-165dBm
tracking
sensitivity
extends positioning coverage into place like urban canyons
and
dense
foliage
environment
where the
GPS was not
possible
before.
The small form factor and low power consumption make the module
easy to integrate into
portable device like PNDs, mobile phones, cameras and vehicle navigation systems.
