Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive processors are used to read raw GNSS data, then location accuracy is improved, but cost and power consumption increase
Solution Approach 1:
The patent introduces an intermediary processing system that receives raw GNSS data and processes it through multiple correction layers (ionospheric delay correction, tropospheric delay correction, multipath effect correction) before providing location information to the mobile device. This intermediary system enables accurate location determination without requiring expensive processors in every mobile device, thus reducing power consumption while maintaining high accuracy.
Solution Approach 2:
The patent creates a corrected version of GNSS data by generating virtual reference station corrections and transmitting them to mobile devices. Instead of requiring each device to process raw data with expensive hardware, the system copies the correction algorithms and correction data to multiple devices, enabling them to achieve high accuracy location using standard processors with lower power consumption.

3Measurement precision
If GNSS signals are used in urban environments, then location data is obtained, but multipath signal distortions reduce accuracy
Solution Approach 1:
The patent converts the harmful multipath signal distortions into beneficial information by using the same reflected signals to calculate correction factors. The system measures the actual received signals, compares them with expected direct-path signals, and uses the differences to generate correction data that compensates for multipath effects, thereby improving location accuracy in urban environments.
