Code Phase Origin Reference for Multi-GNSS Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning protocols in wireless communication networks face challenges in efficiently sharing and utilizing code phase related information across different Satellite Positioning Systems (SPS), particularly in supporting multiple Global Navigation Satellite Systems (GNSS) and varying reference time values, which hinders accurate position determination processes.
Innovation Solution
The implementation of a method that establishes a 'generic' code phase origin reference value, allowing for the encoding and transmission of code phase values associated with various SPS, enabling devices to re-establish corresponding code phase values based on this reference, thereby facilitating efficient communication and position determination across multiple GNSS resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current positioning protocols are used to share code phase information across different SPS, then position determination can be performed, but compatibility and efficiency are reduced due to varying reference time values and multiple GNSS systems
Solution Approach 1:
The patent establishes a universal code phase origin reference value that serves as a common reference for multiple GNSS systems (GPS, GLONASS, Galileo, QZSS). This single reference value enables code phase information from different SPS to be encoded and shared uniformly across the wireless network, eliminating the need for separate reference time handling for each GNSS system and improving interoperability.
2Productivity
If code phase values from multiple SPS are shared without a generic reference, then position determination information can be transmitted, but communication efficiency is hindered
Solution Approach 1:
The code phase origin reference value acts as an intermediary that mediates between the actual code phase values from multiple GNSS systems and the devices needing this information. By encoding code phase values relative to this common reference, the system maintains accurate position determination information while enabling efficient communication through standardized message formats that can be universally decoded.
