The  GotopGT-1612-MTR is a complet
e GPS engine module that features super
sensitivity, ultra low power and small for
m factor. The GPS signal is applied to th
e antenna  input of module, and a comple
te serial data message with position, velo
city and time information is presented at t
he serial interface with NMEA protocol or
custom protocol.
Its  –165dBm tracking sensitivity exten
ds positioning coverage into place like ur
ban canyons and dense foliage environm
ent where the GPS was not possiblebef
ore. The small form factor and low power
consumption make the module easy to i
ntegrate into portable device like PNDs,
mobile phones, cameras and vehicle navi
gation systems.
Applications
  LBS (Location Based Service)
