Solution Overview
Problem
The high calibration costs and low benefits of radio determination satellite systems (RDSS) in consumer-level terminals, such as mobile phones and watches, due to the use of non-ideal general radio frequency devices and costly dedicated calibration devices.
Innovation Solution
Reusing the calibration path of a first communication system, such as cellular, Bluetooth (BT), or Wi-Fi, to calibrate both the satellite communication system and satellite positioning system, reducing hardware costs and layout area by constructing a loopback path for calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated calibration device is used to calibrate the RDSS, then calibration accuracy is improved, but calibration cost increases and device complexity increases
Solution Approach 1:
The patent applies universality by enabling the calibration path of the first communication system to serve dual purposes: calibrating both the first communication system itself and the satellite communication system. This multi-functional approach eliminates the need for a separate dedicated calibration device, thereby reducing device complexity while maintaining calibration accuracy through the shared calibration path.
2Measurement precision
If a dedicated calibration device is used to calibrate the RDSS, then calibration accuracy is improved, but calibration cost increases
Solution Approach 1:
The patent implements universality by allowing the calibration path to be shared between the first communication system and the satellite communication system. This enables one calibration path to perform multiple calibration functions, thereby reducing hardware requirements and calibration costs while maintaining accurate calibration results.
Solution Approach 2:
The patent applies self-service by enabling the first communication system to calibrate the satellite communication system through its existing calibration path. This self-service mechanism eliminates the need for external dedicated calibration devices, reducing costs while maintaining calibration accuracy through the reusable calibration infrastructure.
3Measurement precision
If separate calibration paths are used for the first communication system and satellite communication system, then calibration accuracy is improved, but layout area increases
Solution Approach 1:
The patent applies merging by combining the calibration paths of the first communication system and the satellite communication system into a shared calibration path. This consolidation reduces the overall layout area required for calibration functionality while maintaining calibration accuracy through the integrated path design.
Solution Approach 2:
The patent implements universality by designing a shared calibration path that serves both the first communication system and the satellite communication system. This multi-functional approach eliminates the need for separate calibration paths, thereby reducing the layout area while preserving calibration accuracy through the common calibration infrastructure.

AI summary
A processing apparatus comprises a transmit path of a first communication system, a transmit path of a satellite communication system, a receive path of the satellite communication system, and a first calibration path. The first communication system and the satellite communication system share the receive path of the satellite communication system. A first end of the first calibration path is connected to the transmit path of the first communication system, or a first end of the first calibration path is connected to the transmit path of the satellite communication system. A second end of the first calibration path is connected to the receive path of the satellite communication system. When the first calibration path is connected to the satellite communication system, the first calibration path may be used to calibrate the satellite communication system.
