Positioning Chip Working Modes for Accuracy-Power Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high power consumption of positioning chips in electronic devices, particularly due to unnecessary activation of all functions by default, leads to inefficient energy usage and reduced device lifespan.
Innovation Solution
A method to control the positioning chip by determining its working mode based on the application's requirements, adjusting constellation and frequency configurations to match the needed accuracy, thereby optimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the positioning chip activates all functions by default to ensure high positioning accuracy, then positioning precision is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic working mode switching for the positioning chip, allowing it to transition between different operational states (first working mode with full constellation and multi-frequency for high accuracy, second working mode with reduced constellation for lower accuracy) based on real-time application requirements and signal conditions, thereby optimizing power consumption while maintaining necessary positioning accuracy
Solution Approach 2:
The patent changes key operational parameters of the positioning chip including constellation configuration (full constellation vs. reduced constellation), frequency mode (multi-frequency vs. single frequency), and working mode (first working mode vs. second working mode) to balance positioning accuracy requirements with power consumption constraints
2Measurement precision
If the positioning chip uses full constellation and multi-frequency mode to achieve high positioning accuracy, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the positioning chip's operational capabilities into distinct working modes and constellation configurations, allowing the system to select appropriate subsets of satellite constellations and frequency modes based on positioning accuracy requirements, thereby reducing the effective complexity while maintaining the capability for high-precision positioning when needed
