General Description
The SKG17A 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.
It is based on the high performance features of the
MediaTek MT3339 single-chip architecture, 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.
Applications
LBS (Location Based Service)
PND (Portable Navigation Device)
Vehicle navigation system
Mobile phone
