The  Gotop  GUM-5546-MTBDMU15is
a complete GPS/BeiDou engine module t
hat features super sensitivity, ultra low po
wer and small form factor. The GPS/BeiD
ou signal is applied to the antenna input
of module, and a complete serial data me
ssage with position, velocity and time info
rmation is presented at the serial interfac
e with NMEA protocol or custom protocol.
I ts  –165dBm tracking sensitivity exten
ds positioning coverage into place like ur
ban canyons and dense foliage environm
ent where the  GPS/BeiDou was not possi
ble before. The small form factor and low
power consumption make the module ea
sy to integrate into portable device like P
NDs, mobile phones, cameras and vehicle
navigation systems.
