Mobile GNSS Antenna Support for Precise RTK Boundary Definition
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 and flexible antenna module with a GNSS satellite position locator, integrated with a charging station and mobile support, allowing for adjustable installation and improved satellite signal reception, enabling centimeter-level accuracy and reducing costs by allowing the GNSS position detector to be used for multiple purposes and facilitating movement and protection from environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed GNSS position detector is used to define the reference station in RTK configuration, then position accuracy is improved, but device flexibility and adaptability deteriorate
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed reference station into a mobile platform. The charging station with integrated GNSS antenna can be relocated to different positions within the working area, allowing the system to adapt to various operational requirements while maintaining RTK positioning accuracy. This mobility enables flexible deployment without sacrificing measurement precision.
Solution Approach 2:
The charging station serves multiple functions: it charges the mobile device, provides a stable platform for the GNSS antenna, and acts as a mobile reference station. This multi-functionality eliminates the need for separate fixed infrastructure, improving both adaptability and system simplicity while maintaining positioning accuracy.
2Measurement precision
If a fixed structure is used to mount the GNSS position detector, then signal reception quality is improved, but system complexity and installation difficulty increase
Solution Approach 1:
The patent merges the GNSS antenna mounting function with the charging station. Instead of requiring separate fixed mounting structures, the charging station integrates both charging capability and antenna support, simplifying installation while ensuring optimal signal reception through elevated positioning.
3Measurement precision
If the GNSS position detector is placed in an open unobstructed location, then satellite signal reception is improved, but safety risks increase due to boundary definition imprecision
Solution Approach 1:
The system uses real-time feedback from the mobile device's position data to dynamically adjust and refine the working area boundary definition. This continuous feedback mechanism ensures that even with mobile positioning, the system can accurately define safe operational boundaries, maintaining safety while allowing flexible signal reception locations.
