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 smaller distance to flying objects, but the number of satellites required increases enormously and system complexity increases
Solution Approach 1:
The patent combines surveillance satellites and communication satellites into a unified satellite system where communication satellites serve dual purposes: maintaining communication circuits and transmitting surveillance data. This merging reduces the total number of satellites needed while preserving detection performance through the use of multiple LEO satellites for surveillance and the same constellation for data transmission.
Solution Approach 2:
Communication satellites are designed to perform multiple functions: maintaining communication circuits with ground stations and transmitting surveillance data from surveillance satellites. This multi-functionality eliminates the need for separate dedicated communication infrastructure, reducing system complexity while enabling continuous surveillance operations.
2Measurement precision
If low Earth orbit satellites are used for surveillance, then detection capability is enhanced, but continuous surveillance and communication require dynamic reconfiguration of satellite positions and communication routes
Solution Approach 1:
The system dynamically adjusts communication routes and satellite positions to maintain continuous surveillance capability. As LEO satellites move along their orbits, the communication ground center continuously reconfigures communication circuits to track satellite positions, enabling uninterrupted data transmission and surveillance coverage despite the dynamic nature of LEO operations.
Solution Approach 2:
The communication ground center receives real-time information about satellite positions and communication circuit status, using this feedback to dynamically reconfigure communication routes. This feedback mechanism ensures continuous surveillance operation by automatically adapting to satellite motion and maintaining optimal communication pathways.
3Reliability
If numerous LEO satellites are deployed for continuous surveillance, then coverage is improved, but data transmission complexity and required communication infrastructure increase enormously
Solution Approach 1:
The patent merges communication and surveillance functions into a single integrated system. Communication satellites that would traditionally be separate entities are instead utilized as part of the surveillance constellation, transmitting surveillance data through the same satellite network that provides communication services. This integration dramatically reduces communication infrastructure requirements while maintaining continuous coverage.
Solution Approach 2:
The satellite system is designed with universal functionality where communication satellites serve both as communication relays and as data transmission channels for surveillance information. This multi-functionality eliminates the need for separate dedicated communication infrastructure, reducing overall system complexity while enabling reliable continuous surveillance.
4Ease of operation
If stationary orbit satellites are used, then communication circuits appear locked relative to earth fixed coordinates simplifying configuration, but distance to flying objects increases reducing infrared detection performance
Solution Approach 1:
The system transitions from static GEO satellite configuration to dynamic LEO satellite operations, where satellites continuously move along their orbits. This dynamic approach provides closer proximity to flying objects for improved infrared detection, while the ground control centers dynamically adjust communication circuits to track satellite positions, maintaining operational effectiveness despite the loss of geometric locking.
