GNSS Mouse Receiver


LS2303x-UDG Ultra-High Performance  GNSS Mouse Receiver / Untethered Dead Reckoning
LS2303x-UDG Ultra-High Performance GNSS Mouse Receiver / Untethered Dead Reckoning

LS2303x-UDG series products are complete GNSS receivers based on the proven technology. The series products are embedded with LOCOSYS MC-1612-DG module, 3D accelerometer and 3D gyroscope, as well as dead reckoning software. They can provide dead reckoning navigation without any odometer connection. The extended Kalman filter algorithm combines GNSS and MEMS sensor data with a weighting function that relies on GNSS signal quality. In poor signal reception and
multipath environments, position errors are reduced by dead reckoning. The series products can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS, GALILEO, QZSS and SBAS. Besides, they feature high sensitivity, low power, and provide user the superior performance. The far-reaching capability meets the sensitivity requirements of car navigation as well as other location-based applications.
