UAV Relay Flight Routing for Flexible Data Acquisition Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned Aerial Vehicles (UAVs) have limited communication coverage due to their reliance on relay base stations, restricting their flight routes to a single linear direction, which hampers data acquisition missions.
Innovation Solution
A method and system that involve acquiring a mission flight route for a first UAV, generating a relay flight route for a second UAV based on the mission flight route and relay base station distribution, and controlling both UAVs to perform data acquisition missions, with the second UAV communicatively connected to a target relay base station, thereby extending communication coverage.

Engineering Contradiction Analysis
1Area of stationary object
If UAVs connect relay base stations to expand communication range, then communication coverage is improved, but flight route flexibility deteriorates (UAVs can only fly along a single linear direction of relay base stations)
Solution Approach 1:
The patent introduces a relay UAV as an intermediary communication node between the mission UAV and ground relay base stations. The relay UAV flies alongside the mission UAV and maintains wireless communication links with both the mission UAV and ground base stations, enabling the mission UAV to operate beyond the direct communication range of ground base stations while maintaining flexible flight routes.
Solution Approach 2:
The patent transitions from a two-dimensional ground-based relay system to a three-dimensional aerial relay system by deploying relay UAVs in the air space. This adds a vertical dimension to the communication infrastructure, allowing mission UAVs to maintain communication coverage over larger areas without being constrained to linear flight paths between ground base stations.
2Device complexity
If UAVs rely on ground relay base stations, then communication infrastructure is simplified, but communication coverage is limited
Solution Approach 1:
The patent segments the communication infrastructure into multiple functional components: ground relay base stations for fixed coverage areas, relay UAVs for mobile extended coverage, and mission UAVs for data acquisition. This segmentation allows the system to expand coverage dynamically by deploying relay UAVs to specific areas without requiring additional ground base stations, thus maintaining infrastructure simplicity while expanding coverage.
3Device complexity
If single relay base station is used, then system complexity is reduced, but flight route options are restricted
Solution Approach 1:
The patent creates a dynamic communication system where relay UAVs can be deployed and repositioned based on mission requirements. The relay UAV flies in proximity to the mission UAV and adjusts its position to maintain optimal communication links, enabling the mission UAV to access diverse flight routes and areas that would be inaccessible with fixed ground base stations alone.
