RTK Base Station Siting Through Shared Satellite Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting the installation position of an RTK base station for mowers are inconvenient for users and do not consider the impact on RTK performance, leading to inaccurate positioning due to frequent movement of the base station.
Innovation Solution
Acquire satellite observation data at multiple sampling points along a target map, determine target sampling points based on satellite observation frequency bands, and recommend the base station installation position based on the number of common satellite observation frequency bands, ensuring a large number of satellites are observable by both the mower and the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the base station constantly moves positions to compute and compare satellite observation signals, then the site selection range can be obtained, but the user operation becomes inconvenient and time-consuming
Solution Approach 1:
The system performs preliminary satellite observation data collection at multiple candidate positions before final base station installation. By pre-collecting and analyzing satellite observation data at different locations, the system identifies optimal installation positions in advance, eliminating the need for repeated base station movement during actual operation. This preliminary action ensures both positioning accuracy and operational convenience.
2Measurement precision
If the base station constantly moves positions to compute and compare satellite observation signals, then the site selection range can be obtained, but the process requires moving the base station many times
Solution Approach 1:
The system collects satellite observation data at multiple candidate positions during an initial survey phase before final installation. By performing all necessary measurements in advance and analyzing the data to identify optimal positions, the system eliminates repeated movement during operational phases, significantly reducing total time required.
Solution Approach 2:
The system uses the mower's satellite observation capabilities to copy or simulate base station observation data at multiple candidate positions. Instead of physically moving the actual base station multiple times, the mower collects satellite observation data at different locations, creating virtual copies of base station observations to evaluate candidate positions efficiently.
3Ease of manufacture
If the existing method selects base station position without considering RTK performance, then the installation is simple, but the mower positioning accuracy deteriorates
Solution Approach 1:
The system replaces complex mechanical trial-and-error base station positioning with a computational approach. By using satellite observation data collected by the mower to evaluate candidate positions and predict RTK performance, the system identifies optimal locations through data analysis rather than physical experimentation, ensuring both installation simplicity and positioning accuracy.
