Method for Position Determination by Tracking GNSS Satellites Using Vector Tracking Loops - A simplified explanation of the abstract
This abstract first appeared for US patent application 18582194 titled 'Method for Position Determination by Tracking GNSS Satellites Using Vector Tracking Loops
The patent application describes a method for position determination using GNSS signals and a GNSS receiver with multiple channels connected to a common Kalman filter to form vector tracking loops.
- The method involves receiving GNSS signals, processing them iteratively using vector tracking loops, and aggregating measurements to a virtual value for a set number of iterations.
- The information from the GNSS signals is then entered into the common Kalman filter to determine the position.
- This process is repeated for subsequent iterations to continuously refine the position determination.
Potential Applications: - Navigation systems - Autonomous vehicles - Surveying and mapping - Geolocation services
Problems Solved: - Improved accuracy in position determination - Efficient processing of GNSS signals - Enhanced reliability in tracking and positioning
Benefits: - Higher precision in location-based services - Better performance in challenging GNSS environments - Increased efficiency in navigation systems
Commercial Applications: Title: Advanced Position Determination Technology for Navigation Systems This technology can be utilized in various commercial applications such as: - Automotive industry for autonomous driving systems - Aerospace industry for precise navigation in aircraft - Surveying and mapping companies for accurate data collection
Questions about the technology: 1. How does this method improve the accuracy of position determination compared to traditional GNSS receivers? 2. What are the potential challenges in implementing this technology in real-world applications?
Original Abstract Submitted
A method is disclosed for position determination by receiving GNSS signals using a GNSS receiver including a plurality of channels, which can be connected in a data-conducting manner to a common Kalman filter to form a plurality of vector tracking loops such that each received GNSS signal can be processed in an iterative manner using a corresponding vector tracking loop while taking into account the measurements returned by the common Kalman filter. The method includes (a) receiving GNSS signals, (b) processing a received GNSS signal using a corresponding vector tracking loop such that the information contained in the GNSS signal is determined while taking into account a virtual value, wherein the virtual value is generated such that measurements to be returned by the common Kalman filter are aggregated to this virtual value for a predefined number of iterations, (c) entering the information determined from the GNSS signal into the common Kalman filter, (d) determining the position using the common Kalman filter based on the information determined from the GNSS signal, and (e) repeating steps (a) to (d) for subsequent iterations.
