The  GotopGT-1612-MT is a complete
GPS engine module that features super
sensitivity, ultra low power and small form
factor. The GPS si gnal is applied to the
antennainput of module, and a complete
serial data message with position, velocit
y and time information is presented at th
e serial interface with NMEA protocol or c
ustom 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 possible  bef
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)
