Engineering Contradiction Analysis
1Reliability
If GPS receiver is used to determine position and velocity data, then position and velocity information can be obtained, but the data becomes unreliable when GPS signals are weak or unavailable
Solution Approach 1:
The patent combines GPS receiver with an on-chip gyrator (motion sensor) to create a hybrid positioning system. The gyrator provides motion parameters (acceleration, velocity) that complement GPS position data, allowing the system to maintain reliability when GPS signals are weak or unavailable by using inertial measurement data to fill gaps or correct GPS deficiencies.
2Measurement precision
If motion parameters are generated using on-chip gyrator, then accurate motion data is provided, but device complexity increases
Solution Approach 1:
The gyrator is implemented as an on-chip component within the RF integrated circuit, nesting the motion sensing functionality inside the existing GPS receiver chip. This integration approach reduces overall device complexity compared to using separate discrete components, while still providing accurate motion parameter measurements through the embedded gyroscope structure.
