Space and satellite systems/
Tasking and downlinkTasking and downlink, inside Space and satellite systems: tasking, mission planning and revisit analysis, shared antenna networks, pass scheduling and resource management, data delivery to cloud and edge and more. Every item is traced to its specification, from OGC API - Connected Systems Part 2 (commands and tasking) to OGC Sensor Planning Service 2.0, and runs on the open Observatory Protocol.
Plan with usArchitectureThe protocol01What it is
Every platform, sensor, processing level and ground-segment step that turns remote measurements of the Earth into calibrated, analysis-ready evidence for a site, a region or a network. Everything on the ground that talks to spacecraft: gateways and teleports, user terminals, modems and software-defined radio, shared antenna networks, CCSDS protocol stacks, mission control, data processing and the spectrum coordination behind each earth station. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
Remote sensing and Earth observation
Choosing what to acquire and when, modelling revisit, look angle and cloud risk against need.
We design and operate.
OGC API - Connected Systems Part 2 (commands and tasking) · OGC Sensor Planning Service 2.0
Ground segment
Pay-per-pass access to antennas across many sites so missions do not have to build their own.
We design, integrate and operate.
CCSDS 910.4-B (cross support reference model) · CCSDS 911.1-B (SLE return all frames)
Ground segment
Booking, deconfliction and configuration of antennas and modems for each contact.
We design and operate.
CCSDS cross support service management
Ground segment
Moving downlinked data straight from the antenna site into processing at the edge or in regional data centres.
We design, integrate and operate.
OGC API - Processes · SpatioTemporal Asset Catalog (STAC) specification
Ground segment
Decommutation, calibration, geolocation and geophysical retrieval that turn raw downlink into usable products.
We design, integrate and operate.
CEOS Analysis Ready Data framework · ISO 19115-1 (metadata)
Ground segment
Products corrected and packaged to a common specification so users can analyse them without reprocessing.
We design and operate.
CEOS Analysis Ready Data product family specifications
Ground segment
Automated chains from request to delivered product for time-critical uses such as fire and flood.
We design, integrate and operate.

03On the grid
The open networks on the grid today, over real relief and the geodesic cells we count them into, filtered to the space domain this area serves. A site built here enrols into the same grid.
