Engineering Contradiction Analysis
1Reliability
If positioning resources are collected in GNSS shadow area, then positioning capability is improved, but encoding efficiency deteriorates
Solution Approach 1:
The patent segments positioning resources into distinct types (wireless communication signals, sensing signals, sensor data) and assigns specific index ranges to each type. This segmentation enables efficient encoding by systematically organizing diverse positioning resources into structured sequence formats, resolving the encoding efficiency problem while maintaining comprehensive positioning capability in GNSS shadow areas.
2Measurement precision
If various positioning resources are collected, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal encoding framework that handles multiple types of positioning resources (wireless signals, sensing signals, sensor data) through a unified sequence structure. By defining general index allocation rules and standardized encoding formats that work across different resource types, the system achieves multi-functionality without proportionally increasing complexity, enabling accurate positioning while maintaining manageable system structure.

AI summary
Disclosed are a system and method for encoding, in the form of a sequence, various types of positioning resources that are collected in order to support various types of positioning in a GNSS shadow area. An encoding system based on a positioning resource sequence that supports continuous hybrid positioning includes an input interface device configured to collect positioning resources in a positioning target space, memory in which a program that performs encoding on the positioning resources has been stored, and a processor configured to execute the program. The processor allocates an index to the positioning resource by considering the type of each positioning resource and encodes the positioning resource in the form of a sequence.
