Solution Overview
Problem
Existing GNSS satellite geolocation systems in land maintenance operations suffer from limited accuracy, especially in RTK configurations, which are rigid and require a fixed reference station with a power supply, leading to safety risks and high costs.
Innovation Solution
A flexible RTK configuration using a portable antenna module with a mobile support that can be easily positioned and powered, ensuring accurate satellite signal reception while allowing the definition of the working area perimeter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed reference station is used in RTK configuration, then positioning accuracy is improved to centimeter-level precision, but device flexibility and ease of movement deteriorate
Solution Approach 1:
The patent transforms the fixed reference station into a mobile unit that can be easily transported and repositioned. The antenna module is integrated into a mobile support structure with wheels, allowing the reference station to move dynamically while maintaining its positioning function. This resolves the contradiction by making the previously static system adaptable and movable.
Solution Approach 2:
The mobile support structure serves multiple functions: it supports the antenna module, provides mobility through wheels, and includes a power supply system. This multi-functional design allows a single device to fulfill both positioning and mobility requirements, eliminating the need for separate fixed infrastructure.
2Measurement precision
If a fixed reference station with power supply is installed, then positioning accuracy is improved, but installation complexity and cost increase
Solution Approach 1:
The mobile reference station is equipped with its own power supply system (battery) and can be autonomously positioned and operated without requiring external power infrastructure. The unit serves itself by carrying all necessary components including the antenna module, control unit, and power source, eliminating complex installation requirements.
Solution Approach 2:
The system is divided into modular components: the antenna module, control unit, power supply, and mobile support structure with wheels. This segmentation allows each component to be independently designed and assembled, simplifying installation and maintenance while maintaining overall system functionality.
3Ease of operation
If satellite geolocation detectors are used, then basic positioning is achieved, but positioning accuracy deteriorates due to signal obstructions and limited precision
Solution Approach 1:
The mobile reference station acts as an intermediary between the satellites and the mobile device. It receives satellite signals, processes them through the control unit, and provides corrected positioning data to the mobile device. This intermediary function enhances accuracy by eliminating errors that occur in direct satellite-to-device communication, especially in signal-obstructed environments.
