Space safetySpace safety, inside Space and satellite systems: TT&C radio links, telemetry and telecommand protocols, ranging and orbit determination, space link security and more. Every item is traced to its specification, from CCSDS 401.0-B (RF and modulation systems) to ECSS-E-ST-50-05C (RF and modulation), and runs on the open Observatory Protocol.

01What it is
The space segment end to end: orbits and constellations, spacecraft buses, communications and Earth observation payloads, inter-satellite links, tracking and command, space safety, launch, and the licensing and filings that let a system operate over a site. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
Satellite and space systems
S and X band links for housekeeping telemetry, commanding and ranging throughout the mission.
We design, integrate and operate.
CCSDS 401.0-B (RF and modulation systems) · ECSS-E-ST-50-05C (RF and modulation)
Satellite and space systems
Packet and frame standards that let ground systems and spacecraft from different suppliers interoperate.
We design, integrate and operate.
CCSDS 132.0-B (TM space data link) · CCSDS 232.0-B (TC space data link) · ECSS-E-ST-70-41C (packet utilisation standard)
Satellite and space systems
Ranging, Doppler and GNSS-derived tracking that produce the orbit solutions every pass and manoeuvre depends on.
We design and operate.
CCSDS 414.1-B (pseudo-noise ranging) · CCSDS 503.0-B (Tracking Data Message)
Satellite and space systems
Authentication and encryption of command and telemetry links so spacecraft accept only authorised commands.
We design, integrate and operate.
CCSDS 355.0-B (Space Data Link Security) · NIST IR 8270 (cybersecurity for commercial satellite operations)
Satellite and space systems
Screening of close approaches and planning of avoidance manoeuvres using standard conjunction messages.
We operate and support.
CCSDS 508.0-B (Conjunction Data Message) · ISO 24113 (space debris mitigation)
Satellite and space systems
Radar, optical and passive RF tracking of objects in orbit, and fusion of shared catalogue data.
We design, integrate and operate.
CCSDS 503.0-B (Tracking Data Message) · UN COPUOS Guidelines for the Long-term Sustainability of Outer Space Activities
Satellite and space systems
Solar and geomagnetic monitoring that predicts drag, charging, radiation and ionospheric effects on links and GNSS.
We integrate and operate.
NOAA Space Weather Scales · ECSS-E-ST-10-04C (space environment)
Satellite and space systems
Design and operations that limit debris and remove spacecraft from protected orbits after mission end.
We design and operate.
ISO 24113 (space debris mitigation) · IADC Space Debris Mitigation Guidelines · FCC orbital debris rules (five-year post-mission disposal)
Frontier · Satellite and space systems
Inspection, refuelling, life extension and removal missions that change how space assets are maintained.
We design and support.
ISO 24330:2022 (RPO and on-orbit servicing)
