This study introduces a novel method for rocket tracking and impact point determination using telemetry and slant-range data. This approach significantly reduces the search area for payload recovery.
Area of Science:
- Aerospace Engineering
- Geospatial Analysis
- Telemetry Systems
Background:
- Accurate determination of rocket flight paths and impact points is crucial for mission success and safety.
- Traditional radar tracking can be resource-intensive and may have limitations in certain environments.
Purpose of the Study:
- To present an alternative method for determining rocket trajectory and impact points.
- To evaluate the efficacy of combining telemetry antenna data with slant-range information.
- To compare the accuracy of this novel method against traditional radar tracking.
Main Methods:
- Merging angular data (Azimuth, Elevation) from a telemetry antenna with radial distance from a slant-range device.
- Analyzing position components using the telemetry antenna in automatic target tracking mode.
- Comparing the derived impact point with data obtained from radar tracking.
Main Results:
- The combined telemetry and slant-range system accurately determined the rocket's impact point.
- The calculated impact point was within 237.64 meters of the radar-tracked impact point.
- This method demonstrated a significant reduction in the potential search area.
Conclusions:
- The telemetry and slant-range data fusion offers a viable and effective alternative for rocket tracking.
- This method can enhance the efficiency and reduce the cost of payload recovery operations.
- The system provides valuable supplementary location data for pinpointing impact zones.
