In the actual satellite navigation and positioning, GNSS satellite navigation is usually due to some errors in the links lead to positioning deviation, positioning errors arising from the following three reasons:
Satellite side: satellite clock error, satellite orbit error, ephemeris error.
Propagation side: ionospheric delay Tropospheric delay
User side: multipath Antenna phase center error
In view of the above analysis of satellite navigation and positioning errors, SKYLAB introduces SKG12UR, a high-precision navigation and positioning module that supports RTK differential positioning and corrects the errors through the base station.
SKG12UR positioning module, integrated with single-frequency algorithm, supports BDS and GPS dual-star system at the same time, and with the high-precision positioning service of the national BeiDou augmentation network, it can achieve real-time positioning accuracy at the decimeter level.
With industry-leading navigation sensitivity of -167dBm and A-GNSS service, the module can realize the best navigation and positioning performance, making it possible to achieve excellent positioning accuracy in urban canyons and under dense trees.
It is especially suitable for high-precision vehicle navigation and portable handheld positioning terminals.
