Previously mentioned in the shade, high buildings, overpasses, tunnel construction in the mountains, underground parking lots and other sites, the signal is poor or even lost, GPS positioning can not be applied, but can be applied to inertial navigation to give accurate navigation and precise positioning information content.
Inertial navigation and communication satellite navigation composition application, can flexibly use inertial navigation system software and communication satellite navigation system software advantages, and then according to the best possible optimization algorithm — Kalman filter optimization algorithm combined with the two navigation optimization algorithms, you can get the best navigation results; Especially when the communication satellite navigation system software can't work, the use of inertial navigation system software to prompt the navigation system software has been working, improving the navigation and positioning information content. Especially when the communication satellite navigation system software can't work, the inertial navigation system software is used to make the navigation system software work all the time, which improves the stability of the operating system.
Inertial navigation and GPS navigation module:
The inertial navigation module SKM-4DX clearly puts forward the intelligent identification and optimization algorithm of communication satellite navigation accuracy, according to the content of high-precision navigation information given by the composition navigation, it identifies the precise positioning accuracy of communication satellite navigation, if the accuracy of the communication satellite navigation is good, then it will carry out the composition navigation, and once it is found that the data signals of the communication satellite navigation are very poor or even the data signals are lost, then it will carry out the pure inertial navigation, and it will also carry out the pure inertial navigation, and it will also carry out the pure inertial navigation. Inertial navigation module SKM-4DX navigation module completes the independent conversion of composition navigation and pure inertial navigation.
Inertial navigation module SKM-4DX advantages:
(1) It can detect and calibrate the deviation of the inertial guidance system and improve the navigation accuracy.
(2) Filling the problem of broken data signals of communication satellite navigation, improving the working ability of navigation.
(3) Enhancing the redundancy of observation information, improving the ability to detect abnormal deviations, and improving the fault-tolerance mechanism of the system software.
(4) Improve the anti-interference of the navigation system software and improve the integrity.
