General Description
The DM1616S-B is a complete GPS&Beidou engine module that features super sensitivity, ultra low power
and small form factor.The GPS&Beidou 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 .
Its -165dBm tracking sensitivity extends positioning coverage into place like urban canyons and dense
foliage environment where the GPS&Beidou 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
