Engineering Contradiction Analysis
1Reliability
If laser-based architecture is used for training simulation, then the system is simple and easy to operate, but it fails to accurately simulate real-life ballistic effects such as bullet drop, wind effects, and penetration
Solution Approach 1:
The patent replaces the optical laser-based trajectory indication system with a computational ballistic calculation system. Instead of using lasers to physically trace the projectile path, the system uses processors to calculate ballistic trajectories based on sensor data (accelerometers, gyroscopes, magnetometers) and environmental factors (wind, temperature, precipitation). This substitution enables realistic ballistic effects simulation while reducing optical hardware complexity.
Solution Approach 2:
The system dynamically adjusts ballistic calculation parameters based on real-time sensor measurements and environmental conditions. By changing parameters such as wind velocity, temperature, precipitation, and weapon characteristics in the ballistic equations, the system accurately simulates how these factors affect projectile trajectory, thereby improving simulation reliability without requiring complex physical modeling.
2Adaptability or versatility
If laser-based systems are used, then the system operates continuously, but lasers fail to penetrate fog or visual cover and are not suitable for simulating artillery weapons
Solution Approach 1:
The ballistic calculation system serves multiple weapon types and environmental conditions through a unified computational framework. The same processor-based architecture can simulate small arms, artillery, and other weapon systems by adjusting ballistic parameters, making the system universally adaptable while maintaining realistic simulation of various weapon behaviors including artillery trajectories that lasers cannot represent.
Solution Approach 2:
Instead of using physical lasers that are limited by line-of-sight and environmental conditions, the system creates a virtual copy of the ballistic trajectory through computational modeling. This virtual trajectory copy can penetrate visual cover and fog in the simulation, accurately representing how real projectiles behave without being constrained by optical limitations.
3Measurement precision
If high-precision position and orientation sensors are used for accurate aimpoint determination, then measurement precision improves, but power consumption increases
Solution Approach 1:
The system dynamically adjusts sensor sampling rates and processing intensity based on operational context. High-precision measurements are taken only when needed for critical aimpoint determinations, while lower-rate updates are used during transit or non-critical phases. This dynamic operation maintains measurement precision when required while reducing average power consumption of the sensor system.
Solution Approach 2:
The system performs preliminary calibration and characterization of sensor performance to establish accurate baseline measurements. By pre-characterizing sensor drift and error patterns, the system can maintain high measurement precision without continuously running sensors at maximum precision levels, thereby reducing power consumption while preserving accuracy through intelligent use of pre-acquired calibration data.
Data Source
AI summary
A base station server of a combat simulation system includes, a communications interface, a processor and a memory. The memory has instructions stored thereon that, when executed by the processor, cause the processor to receive an indication of a trigger pull from a weapon device and receive a data packet from the weapon device. The data packet may include an orientation of the weapon device and a position of the weapon device. The instructions further cause the processor to determine a position and an orientation of a target and identify a ballistic path of a simulated projectile fired from the weapon device. The ballistic path may be based at least in part on the orientation and the position of the weapon device. The instructions further cause the processor to determine a ballistic outcome by identifying whether the ballistic path intersects with the position of the target.
