The  GotopGRM-3030-MTGN is a co
mplete GPS/GNSS engine module that fe
atures super sensitivity, ultra low power a
nd small form factor.The GPS/GNSS sign
al is applied to the antenna input of mod
ule, and a complete serial data message
with position, velocity and time information
is presented at the 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/GNSS  was not possib
le before. The small form factor and low
power consumption make the module eas
y to integrate into portable device like PN
Ds, mobile phones, cameras and vehicle
navigation systems.
Applications
  LBS (Location Based Service)
  PND (Portable Navigation Device)
  Vehicle navigation system
  Mobile phone
