Overview

Focusear is a passive RF tracking system developed by GMV for space surveillance and flight dynamics support. It tracks satellites based on passive RF technology, providing precise tracking data using Time Difference of Arrival (TDoA) and Frequency Difference of Arrival (FDoA) measurements. Focusear currently tracks over 60 GEO satellites emitting in Ku-band over Europe, contributing data to the EU Space Surveillance and Tracking (SST) program. With plans to expand to other GEO regions and MEO/LEO orbital regimes, Focusear offers 24/7 tracking with top-class accuracy and low latency.

Features and Capabilities

• Passive RF Technology: Tracks satellites using RF emissions without active signaling.
• Tracking GEO Satellites: Monitors over 60 GEO satellites in Ku-band over Europe.
• Time and Frequency Difference Measurements: Uses TDoA and FDoA for precise location data.
• Expansion to Other Regions: Plans to track satellites in additional GEO, MEO, and LEO orbits.
• Continuous Tracking: Provides 24/7 satellite tracking with high-frequency data.
• Low Latency: Delivers data with few minutes of delay.
• Top-Class Accuracy: Achieves orbital data with 10ns accuracy (3m equivalent).
• EU SST Integration: Contributes tracking data to the EU Space Surveillance and Tracking program.
• Highly Scalable: Capable of expanding coverage globally across multiple satellite bands.
