SKM-4DX satellite inertial navigation module integrates two navigation algorithms based on Kalman filtering algorithm, and intelligently recognizes the positioning accuracy of satellite navigation. If the satellite navigation accuracy is better, then the combination navigation is carried out; once the satellite navigation signal is found to be very poor, or even lose the signal, then the pure inertial navigation is carried out, so the use of SKM-4DX navigation module can realize the autonomous switching between the combination navigation and the pure inertial navigation.

SKM-4DX Pin Definition: Satellite Inertial Navigation Module Pin Assignment and Definition:
(1) Getting rid of the odometer
Conventional in-vehicle navigation systems often rely on odometers and gyroscopes DR The solution achieves highly accurate navigation and positioning in complex automotive environments. Odometer signals are very complex for many automotive aftermarkets and involve automotive safety. After years of research and development, the SKM-4DX inertial navigation system completely gets rid of the dependence on the odometer when GNSS when the system signal accuracy is reduced or even lost satellite signals. Compared with the existing related products in the market, the performance has been greatly improved.
(2) Vehicle Attitude Angle
SKM-4DX inertial navigation module uses years of research experience in MEMS inertial devices to realize the filtering of gyroscope drift and acceleration vibration signals through adaptive filtering algorithms, which further obtains high-precision attitude information and meets the various needs of vehicle monitoring and navigation applications, such as ramp detection. The elevation and pitch angle of the vehicle can be up to 30 degrees.
(3) 6-axis acceleration sensor
The hardware basis of the inertial navigation system is the BMI160 sensor combined with a gyroscope with an ideal signal-to-noise ratio, enabling the component to provide accurate and reliable measurement results.
Inertial navigation module applications:
(1) Accurate positioning and navigation at underground bus stops such as Futian Transportation Hub in Shenzhen. Using satellite inertial navigation module on buses, buses can accurately announce stops underground;
(2) Provide speed calibration in tunnels to avoid abnormal speeding when just coming out of the tunnel;
(3) Combined with parking lot maps to improve underground parking lot positioning and accurate car search.
(4) High-end front-loaded vehicles are starting to pursue higher accuracy positioning, especially in urban canyons and viaducts
Weak signal scenarios are lower.
