Collision Avoidance

Our responsive autonomous collision avoidance system prevents catastrophic collisions and helps ensure mission safety. This system autonomously generates optimal courses of action to avoid upcoming collision events, saving many hours of otherwise a manual process.

Kayhan high-fidelity software can model various types of propulsions systems, including impulsive thrust, low thrust, and electric propulsion systems. We can also generate avoidance courses of action via differential drag.

Orbit Determination, Orbit Maintenance, and Prediction

Our secure, highly-available, and integrated cloud-based astrodynamics product suite is built with satellite operators’ changing needs in mind. Kayhan advanced orbit determination platform is capable of fusing measurements from various sources and generating precise state knowledge of spacecraft. Our orbit maintenance tool generates optimal maneuver plans to maintain the target orbit for the entire constellation. Finally, our proprietary uncertainty prediction technology can generate and propagate realistic state uncertainty into the future.
