Precision for Transaction Networks

NTN LEO satellites processing financial transactions require exceptional pointing accuracy to maintain communication links and ensure data integrity. Our Attitude and Orbit Control Systems (AOCS) deliver arc-second level precision, critical for high-gain antenna pointing and inter-satellite links.

The navigation suite integrates GPS receivers, star trackers, sun sensors, and magnetometers to provide comprehensive attitude determination. Advanced Kalman filtering algorithms fuse sensor data to achieve position accuracy within meters and attitude knowledge better than 0.01°.

Our gyroscopes and accelerometers undergo rigorous space qualification testing to ensure reliability in the harsh LEO environment. On-orbit calibration procedures compensate for sensor drift, maintaining performance throughout the mission lifetime and ensuring consistent transaction processing capabilities.
