Satcat provides orbit determination services for spacecraft with GNSS telemetry, supporting mission phases from LEOP to on-orbit operations. Runs are executed nominally daily, or on demand, against operator-provided GNSS data and maneuver metadata, and produce predictive and post-fit OEMs with propagated covariance in CCSDS formats, used automatically in downstream risk assessment and coordination.

Sensor Tasking acquires targeted observations from commercial sensor networks for RSOs where catalog accuracy or GNSS telemetry is insufficient. Tasking is centrally managed by Satcat, and the resulting data is fused into orbit determination.
