Mobile GNSS Reference Setup for Precise Working Area Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite geolocation systems in land maintenance, such as gardening and agriculture, face limitations in accuracy and flexibility, particularly with Real Time Kinematics (RTK) configurations, which are rigid and require a fixed GNSS position detector and power supply, leading to inefficiencies and safety risks due to imprecise boundary definition of working areas.
Innovation Solution
A portable antenna module with a GNSS satellite position locator and a flexible installation method using a mobile support, allowing the antenna module to be positioned optimally for satellite signal reception and easily moved or constrained to various locations, while maintaining RTK accuracy and enabling precise definition of working area boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed GNSS position detector is used to define a reference station for RTK configuration, then positioning accuracy is improved, but device flexibility and ease of operation deteriorate due to rigid installation requirements and fixed power supply needs
Solution Approach 1:
The patent makes the reference station dynamic by allowing the GNSS antenna to be temporarily installed on mobile devices (smartphones, tablets, laptops) rather than fixed structures. The antenna can be moved to different locations and devices as needed, transforming a traditionally static reference station into a dynamic, adaptable system that maintains RTK positioning accuracy while gaining operational flexibility.
Solution Approach 2:
The patent enables universal use of common mobile devices as reference stations by equipping them with GNSS antennas. Instead of requiring specialized fixed infrastructure, any mobile device can serve as a reference station, allowing the same hardware to perform multiple functions (positioning, navigation, mapping) across different applications and locations.
2Reliability
If a fixed structure is used to mount the GNSS position detector, then signal reception quality is improved, but installation complexity and cost increase due to infrastructure requirements
Solution Approach 1:
The patent extracts the GNSS antenna from traditional fixed mounting structures (roofs, poles) and relocates it to mobile devices. This separation allows the antenna to be used independently on any device with sufficient processing capability, eliminating the need for complex fixed infrastructure while maintaining signal reception quality through proper antenna placement and selection.
3Ease of operation
If satellite geolocation systems are used for boundary definition, then working area detection is enabled, but boundary definition precision deteriorates due to limited GNSS accuracy
Solution Approach 1:
The patent introduces a mobile reference station as an intermediary between satellites and the mobile device performing boundary detection. By establishing a local RTK reference frame through the mobile reference station, the system achieves centimeter-level boundary definition precision that exceeds standard GNSS capabilities, while maintaining the ease of operation of software-based boundary detection.
