SKM-6DM is a high-performance vehicle integrated navigation module for vehicle navigation field. The module supports GPS, Beidou, GLONASS, Galileo, QZSS satellite receiver chips. Support L1+L5 dual-frequency positioning, three-axis gyroscope, three-axis acceleration, etc.

SKM-6DM provides real-time high-precision vehicle positioning, speed measurement and attitude measurement information through online adaptive integrated navigation algorithm.

When the signal accuracy of the GNSS system is reduced or even the satellite signal is lost, the odometer information is not used. Using pure inertial navigation technology, SKM-6DM can also perform high-precision positioning, speed measurement and attitude measurement on the vehicle carrier alone for a long time. The module can directly output the total mileage, which is convenient for customers to measure the mileage.

Product Features:

◆ High-performance 3-axis gyroscope and 3-axis accelerometer

◆Complete error compensation such as quadrature error/temperature drift

◆ The calibration parameters of each product are inconsistent and anti-piracy

◆ Compact and modular design can save user product space

◆ Plug and play standard communication protocol NEMA0183

◆ No installation angle requirements are convenient for users to install in the car

◆ Support RTCM2.3-3.3 protocol/sub-meter navigation in complex environment

◆ Compliant with RoHS, FCC, CE

Product Advantages:

◆ Eliminate gyro drift to obtain high-precision attitude and heading information

◆ Eliminate vibration acceleration to obtain high-precision speed information

◆ Zero speed correction algorithm can prevent navigation data from drifting

◆ Based on adaptive extended Kalman filter algorithm

◆ Identify and isolate GNSS data with large errors

◆Using pure inertial navigation to achieve high-precision positioning

◆ Autonomous switching between integrated navigation and pure inertial navigation technology
