SDA
Next Generation Space Domain Awareness
Real-time tracking and rapid orbit solutions for dynamic space environments
Modern space operations demand real‑time understanding. Objects maneuver unpredictably, and the most valuable information is what can be sensed and interpreted immediately. ARA’s Space Domain Awareness (SDA) technologies deliver that insight through advanced angular‑vector processing and rapid observational software.

Real‑time or near‑real‑time characterization of orbit changes
Rapid orbit determination at speeds far beyond traditional angles‑only methods
Event‑based processing extracts complete angular vectors from a single optical sensor.
High‑precision angular measurements
Works with low‑cost optical hardware
Enables downstream rapid orbit determination and maneuver detection
Patent‑pending technology that detects and characterizes maneuvers the moment they occur.
Real‑time identification of trajectory changes
Improved custody during rapid or unexpected maneuvers
Earlier warnings for dynamic space events
A patented technique producing accurate orbits in seconds to minutes – an order of magnitude faster than conventional orbit determination.
Orbit determination with just one look
Requires only a single passive optical sensor
No a priori orbit information needed
Supports both tactical and persistent monitoring
Optical tracking solutions designed for extreme ranges out to 1.5 million km. Demonstrated performance on Artemis II, including:
- Orion capsule tracked out to 334,000 km
- Separation of cubesats and adapter ring captured at 73,000 km
Detects and tracks dim, distant cislunar objects
Handles complex three‑body dynamics
