Spacecraft and payloads: a radar satellite with its antenna, wings and thrusters, part by part. The loop, step by step: 1. A spacecraft bus holds its payload steady. 2. The solar wings unfold toward the sun. 3. Sensors check that the response worked. 4. The radar antenna deploys and warms up. 5. Time and place are fixed to every sample. 6. Housekeeping is signed on board. 7. Telemetry reaches the ground. 8. Relays carry the packets without reading them. 9. Signatures are checked before any model runs. 10. Engineers verify every subsystem in turn. 11. The edge releases confirmed results only. 12. The payload is declared ready for tasking. 13. The console shows the evidence with the alert. 14. The whole chain is archived for audit. 15. Everything settles back to idle.

Spacecraft and payloadsSpacecraft and payloads, inside Space and satellite systems: multispectral optical imagers, hyperspectral imagers, synthetic aperture radar (X, C, L band), thermal infrared and fire detection and more. Every item is traced to its specification, from CEOS Analysis Ready Data: Surface Reflectance to ISO 19115-1 (metadata), and runs on the open Observatory Protocol.
Plan with usArchitectureThe protocol01What 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
Visible to shortwave-infrared imagers for land cover, vegetation, water and infrastructure monitoring.
We design and integrate.
CEOS Analysis Ready Data: Surface Reflectance · ISO 19115-1 (metadata)
Satellite and space systems
Hundreds of narrow bands that separate materials, minerals, crop stress and pollutants.
We design and integrate.
CEOS Analysis Ready Data framework · CCSDS 123.0-B (multispectral and hyperspectral compression)
Satellite and space systems
Day-night, all-weather imaging for flooding, ice, ground deformation and maritime monitoring.
We design and integrate.
CEOS Analysis Ready Data: Normalised Radar Backscatter · ITU RR Art. 5 (EESS active allocations)
Satellite and space systems
Thermal bands for wildfire detection, surface temperature, urban heat and industrial monitoring.
We design and integrate.
CEOS Analysis Ready Data: Surface Temperature
Satellite and space systems
Spectrometers and sounders measuring methane, CO2, aerosols, temperature and humidity profiles.
We design and integrate.
WMO OSCAR (observing systems capability review) · WMO WIGOS
Satellite and space systems
Standardised small spacecraft (1U to ESPA-class) that lower the cost of hosted sensing and communications missions.
We design and integrate.
CubeSat Design Specification · ISO 17770 (cube satellites)
Satellite and space systems
Solar arrays, batteries and power conditioning sized to payload duty cycle, eclipse and end-of-life degradation.
We design and integrate.
ECSS-E-ST-20C (electrical and electronic)
Satellite and space systems
Sensors, reaction wheels, magnetorquers and control software that point payloads and antennas within budget.
We design and integrate.
ECSS-E-ST-60-30C (satellite AOCS requirements)
Satellite and space systems
Thrusters for orbit raising, station keeping, collision avoidance and controlled disposal.
We design and integrate.
ECSS-E-ST-35C (propulsion general requirements)
