Communication
Voice, data, telemetry, and mission communications for crewed vehicles.
Communication links the spacecraft, crew, relay assets, ground stations, and mission networks across voice, telemetry, command, optical, and RF paths.
⌁
RF Links
Robust radio links for all ranges.
⌁
Optical Links
High-bandwidth laser communications.
⌁
Telemetry
Health and performance data return.
⌁
Crew Voice / Data
Secure crew communications and files.
Mobile view uses a protected minimum width so pages can be zoomed instead of crushed.
System Overview
| Communications Bands | S-band, X-band, Ka-band, UHF/VHF, optical links, and mission-specific relay paths. |
|---|---|
| Data Return | Adaptive data rates based on range, geometry, weather, and link budget. |
| Antenna Types | High-gain, medium-gain, low-gain, omni, steerable arrays, and deployable apertures. |
| Crew Communications | Voice, messaging, video, files, and low-latency operational data. |
| Redundancy | Dual chains, crosslink, backup transceivers, and relay fallback. |
