Beskrivning

GPS Module GPS Smart Module with Built-in Antenna GNSS module

The DELIN COMM DM1818-B är 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 och time information är presented at
the serial interface with NMEA protocol or custom protocol.
Its -165dBm tracking sensitivity extends positioning coverage into place like urban canyons och
dense foliage environment where the GPS& Beidou was not possible före. 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.
