Benefits of technology

This patented technology proposes two methods for improving the quality or precision of navigational systems that use radio waves from satellites (S) - Satellite Navigation System (GNSS). One approach involves filtering out unwanted noise while maintaining accurate location data. Another technique uses an algorithm called Kalman Filter with time-varyings to estimate the unknown parameters accurately based upon their past behavior over time. By doing this, these techniques can help prevent interference between different sources like GNSS signals without affecting each other's measurements. Overall, they enhance the performance and reliability of navigation devices such as Sputnikovsky Launched In 1997.

Problems solved by technology

This patented describes how accurate location data from different sources like global position system (GPS), smartphone, navigator, etc., may have limitations when it comes across obstructions such as tree roots near homes due to blockages caused by tall structures around them.

Abstract

The invention discloses a satellite navigation positioning signal processing device method and apparatus. The method comprises: receiving a satellite navigation positioning signal; determining a stable part and an unstable part of the satellite navigation positioning signal; filtering the unstable part of the satellite navigation positioning signal and using the stable part of the satellite navigation positioning signal as a filtered satellite navigation positioning signal; and according to the filtered satellite navigation positioning signal, obtaining a positioning result. With the method disclosed by the invention, the influence on the positioning result by a shelter or a reflection signal can be reduced; the positioning result error can be reduced; and the navigation positioning precision can be improved.
