Space traffic is becoming increasingly congested, with thousands of satellites orbiting Earth and raising the risk of potential collisions. The main challenge is predicting and preventing these collisions while preserving the confidentiality of sensitive satellite position data.
Many governments and satellite operators are reluctant to disclose exact satellite locations due to safety, security, or political concerns.
In 2008, the Iridium 33 and Kosmos-2251 satellites collided due to a lack of precise trajectory disclosure by governments. According to publicly available data, the satellites should have passed each other with a buffer of 584 meters.
MPC Implementation
The solution involves using Sharemind MPC technology to perform collision detection calculations without revealing the actual positions of satellites. This allows satellite operators to:
- Protect their proprietary orbital data
- Participate in collision prevention
- Maintain operational security
The technology enables satellite operators to receive collision warnings while keeping their exact satellite positions private. This balance between security and safety represents a significant advancement in space traffic management

SpaceComputer's MPC implementation
We can enable immediate communication between satellites, allowing collision courses to be calculated directly within the SpaceComputer network, all within Earth’s orbit. This approach enhances security by eliminating the need to transmit sensitive data outside the satellite network.
