General Description
The SKG17DT is a high-performance GNSS
all-in-one solution Timing module that features super
sensitivity, ultra low power and small form factor. The RF
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.
It is based on the high performance features of the
single-chip architecture, Its –165dBm tracking sensitivity
extends positioning coverage into place like urban canyons
and dense foliage environment where the GNSS 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.
Applications
Precise timing
LBS (Location Based Service)
