General Description
The SKM81D 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
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
LBS (Location Based Service)
PND (Portable Navigation Device)
Vehicle navigation system
Mobile phone
