- For
- Spaceflight software developers and ground-systems operators
- Worth noticing
- Its checks include Doppler, eclipse, link budget, antenna pointing, thermal behavior, and subsystem telemetry; the page says it uses synthetic or public data.
Field notes
The described pipeline receives CCSDS space packets over UDP, parses them asynchronously with Tokio, and streams JSON over WebSocket for dashboards such as NASA Open MCT. An SGP4 engine supplies look angles, range, and range-rate for cross-checks. The project page identifies a NeXosim hardware-in-the-loop simulator and says the site’s sandbox uses synthetic data; it also links the Rust source and Ephemerust crate.
