Integrate TelemetrySolver as new localization algorithm

[jonnyspicer]

Summary

Integrate the TelemetrySolver (Levenberg-Marquardt TDOA/FDOA solver) into 3lips as a new localization algorithm option alongside the existing EllipseParametric, EllipsoidParametric, and SphericalIntersection methods.

Background

The TelemetrySolver provides:

• Levenberg-Marquardt optimization for TDOA/FDOA localization
• Velocity estimation in addition to position
• Robust convergence on bistatic radar measurements
• Input: 3 simultaneous detections with bistatic range and Doppler
• Output: Single position (LLA) with velocity (ENU)

Implementation Plan

Phase 1: Module Integration (2-3 hours)

• Create TelemetrySolverLocalisation.py wrapper class
• Import TelemetrySolver modules directly (no subprocess calls)
• Add to localization algorithm selection in event.py
• Update Docker configuration to include TelemetrySolver

Phase 2: Testing & Validation (1 hour)

• Test module imports work correctly
• Verify data format conversion from 3lips to TelemetrySolver
• Test with synthetic-adsb data
• Manual verification on map interface

Phase 3: Real Radar Testing

• Test with real radar units
• Compare results with existing localization methods
• Verify positions match ADS-B truth data

Technical Details

Input Format: Same as existing methods (delay in km, Doppler in Hz)
Output Format: Standard 3lips localization format with points array
Dependencies: numpy, scipy (already in 3lips)
API Usage: "localisation": "telemetry-solver"

Files to Modify

• 3lips/event/algorithm/localisation/TelemetrySolverLocalisation.py (new)
• 3lips/event/event.py (add import and registration)
• 3lips/event/Dockerfile (copy TelemetrySolver directory)

Success Criteria

• TelemetrySolver standalone functionality verified
• Module imports work without errors
• Positions appear reasonable on map interface
• Can manually verify positions match expected aircraft locations
• Integration doesn't break existing functionality

Priority

High - needed for real radar testing

Time Estimate

~3-4 hours total for MVP integration ready for real radar testing
