Space & Satellites
In orbit — smaller than the speeches, larger than the jokes.

A serious downstream economy with an upstream that still fits in a cleanroom in Guildford. We introduce payload people to launch people, and both to the ones who need the data.
The British space sector is largely a data business wearing an engineering hat. The upstream is real and rather good — small satellite platforms, payloads, propulsion — but the majority of the value sits downstream, in services built on Earth observation and navigation by companies who would not describe themselves as space companies at all.
For anyone building hardware, the schedule is dominated by qualification rather than design. Thermal-vacuum, vibration, radiation tolerance and outgassing each need a facility slot, a written procedure and someone competent to sign it. Teams routinely underestimate this by a factor of two, then discover that the chamber is booked until the spring.
The interesting collaborations therefore tend to be about mass, power, thermal margin and test discipline, not about ambition. The physics is usually settled. The question is whether the thing survives a launch, an eclipse cycle and five years of nobody being able to reach it.
- Payloads, buses, and ground segment
- Earth observation that answers a question
- Constellations that can be operated on a Tuesday
- Qualification campaigns booked before they are urgent
- Downstream services where the actual value sits
What sits inside
The sub-disciplines people actually search for.
Small satellite platforms
Buses, structures, thermal design and the assembly-integration-test discipline that separates a spacecraft from an expensive circuit board.
Optical and RF payloads
Imagers, spectrometers, inter-satellite optical links, and the packaging that must survive both launch and thermal cycling.
Ground segment and operations
Antennas, scheduling, telemetry and the operational tooling that decides whether a constellation is a business or a hobby.
Earth observation applications
Data products for agriculture, insurance, methane detection and infrastructure monitoring — sold to customers who never mention orbits.
Position, navigation and timing
Resilient timing and alternatives for environments where satellite navigation is jammed, spoofed or simply absent.
Where the UK stands
Without the boosterism, and without the gloom.
- Guildford and Harwell anchor the upstream; the Satellite Applications Catapult sits deliberately between hardware and downstream customers.
- Glasgow builds an unusual number of small satellites for a city with no launch pad.
- Domestic launch remains a work in progress, so most missions still procure a ride elsewhere and plan accordingly.
- The strongest commercial growth is in downstream data services rather than in building spacecraft.
Work that gets commissioned
The shape of a package in this domain.
- Thermal-vacuum and vibration campaigns with a written procedure and pass criteria
- Radiation tolerance assessment and component selection for a defined orbit
- Payload thermal and structural analysis against a launcher environment
- Ground-segment prototyping and operational tooling for a first constellation
- Validation of an Earth-observation data product against ground truth
Where projects come unstuck
Reliably, and usually in week nine.
- Leaving the qualification slot until the design is finished, then queueing
- Mass and power budgets kept in a spreadsheet nobody has reconciled this month
- Optics specified without an outgassing and contamination plan
- A data product with no ground-truth comparison, sold to a customer who will find one
