Descripción
G-mouse Receiver with 4p Line 125mm GPS&Beidou Mouse Receiver
DeliN Comm MOUSE Receiver RM4837-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 anddense 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 vehicl navigation systems.
