Mobile RTK Base Station Scheduling for Wider Positioning Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning systems face accuracy issues and limited range due to signal blocking by buildings and trees, especially when fixed base stations are installed in suboptimal locations.
Innovation Solution
Deploy autonomous mobile machines equipped with RTK-GNSS capabilities that can switch between base and mobile stations, dynamically selecting optimal positions for base station operation based on satellite signal availability and battery status, using management devices to coordinate their movement and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed base stations are installed in suboptimal locations, then installation and maintenance costs are reduced, but positioning accuracy and coverage area are limited due to signal blocking by buildings and trees
Solution Approach 1:
The patent applies the dynamics principle by transitioning from fixed base stations to mobile base stations that can autonomously move to optimal positions. The mobile base station changes its location dynamically based on satellite signal conditions, allowing the system to maintain high positioning accuracy across a wider coverage area while adapting to environmental obstacles like buildings and trees.
2Area of stationary object
If mobile base stations are deployed to expand coverage area, then positioning coverage is improved, but system complexity and coordination requirements increase
Solution Approach 1:
The mobile base station implements self-service by autonomously determining its own movement decisions and navigation paths without requiring complex external coordination. The station independently assesses satellite signal conditions and automatically navigates to optimal positions, significantly reducing system complexity while expanding coverage area.
3Measurement precision
If autonomous mobile machines are used as mobile base stations, then positioning accuracy and coverage are improved, but energy consumption and battery management requirements increase
Solution Approach 1:
The system implements feedback mechanisms where the mobile base station continuously monitors satellite signal conditions and battery status. Based on this feedback, the station makes informed decisions about when to move to maintain optimal positioning accuracy and when to conserve energy, balancing positioning performance with energy consumption through adaptive control.
