Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surveillance is conducted from low earth orbit satellites, then detection performance is improved due to shorter distance to flying objects, but a huge number of satellites are required to maintain constant surveillance and communication lines
Solution Approach 1:
The system segments surveillance functions across multiple LEO satellites in orbital planes, where each satellite covers a specific region. The surveillance function is divided into detection, tracking, and communication components distributed across the satellite constellation, allowing comprehensive coverage with fewer satellites through coordinated operation.
Solution Approach 2:
The patent introduces a multi-dimensional approach by utilizing multiple orbital planes and satellites at different positions. Instead of relying on a single satellite or ground-based system, the solution adds spatial dimensions (orbital altitude, longitudinal/latitudinal positions) to create a three-dimensional surveillance network that achieves global coverage with optimized satellite numbers.
2Measurement precision
If LEO satellites are used for surveillance, then detection capability is improved, but the moving flight positions of LEO satellites complicate the configuration and data transmission method
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing surveillance data and communication routes in advance. The defense information integration center pre-processes target information and prepares communication pathways before actual surveillance operations, reducing real-time computational complexity and enabling faster response despite satellite movement.
Solution Approach 2:
The patent introduces communication satellites as intermediaries between LEO surveillance satellites and ground control. These communication satellites relay data and commands, simplifying the configuration by providing stable communication nodes that mediate the complex moving positions of LEO satellites, thereby reducing direct communication complexity.
3Reliability
If a large number of LEO satellites are deployed for constant surveillance, then coverage is improved, but communication network configuration becomes more complex
Solution Approach 1:
The patent merges surveillance satellites and communication satellites into an integrated system where communication satellites serve dual purposes: maintaining communication networks and supporting surveillance operations. This consolidation reduces overall system complexity by combining functions that would otherwise require separate infrastructure.
Solution Approach 2:
Communication satellites are designed with multi-functionality, serving both as communication relays and as part of the surveillance network. They can transmit surveillance data, receive commands, and provide positioning information, thereby reducing the need for dedicated communication infrastructure and simplifying the overall network configuration.

Function Achieved in This Case
Enables quasi-real-time transmission of flying object information and facilitates accurate and rapid response to flying objects by forming a communication network and predicting flight paths, ensuring effective coping with flying objects.
Implementation Method 1
A promising means of detecting and tracking a flying object in a gliding phase is infrared detection of temperature rise which is caused by atmospheric friction generated when the flying object enters the atmosphere.
