Satellites pass
Wide coverage, but a fixed revisit. Your area is seen minutes at a time, when the orbit allows.
01Stratospheric platforms designed to stay over your area.
Persistent coverage for science, civil and defence. In development.
- Target float altitude, above most air traffic
- 18–25 km
- Target payload on a modular bus
- 4 kg
- Target: closer than low Earth orbit
- 25×
- Target time over one area
- Hours to weeks
Design targets. Platform in development.
Coverage often falls short
when it matters.
The gapAircraft run out
Detail and presence, but limited endurance, crews on board, and grounded by weather and airspace.
02We aim to stay
We are designing stratospheric platforms to hold position over your area for hours to weeks, in the gap between the two.
03A simpler way
to plan for overhead coverage.
Why BSS- 01
Planned station-keeping without propulsion
Our approach steers by altitude, choosing the wind layer that keeps the platform over your area. A simulator built on atmospheric models and live flight data is in development.
- 02
One bus, two sensors
The target design is a modular 4 kg payload that takes either an optical camera or microSAR, so one platform serves different missions.
- 03
Priced by outcome
Customers will pay per hour of coverage and per km², not per flight. We plan to carry the flight risk and the logistics.
From order to data
in three steps.
Process- 1
You order
Draw your area, choose coverage hours, pick optical (day, high detail) or microSAR (day, night, through cloud).
- 2
We hold
We will handle airspace and the flight plan, launch, climb above weather and traffic, and hold over your area by altitude control.
- 3
You get data
We plan to deliver quicklooks during the flight and the full data set within days. Pay per hour of coverage and per km².
One platform.
Two sensors.
Payload
Optical
A gimbaled camera is designed to keep the target in view while the platform drifts, so one flight covers more time on target.
Day · High detailmicroSAR
Radar is designed to see through cloud and at night, for monitoring when optical imagery is blocked.
Day & night · All-weatherTarget design: 4 kg gondola with a common bus. Mass and power figures are sizing estimates.
Designed for customers
who cannot wait for a pass.

Planned continuous watch over a fire front or a flood zone, when satellites are not frequent enough.

the rules.
OperationsWe will place launches away from airport control zones and airways, and the platform will float above airliner levels. Flight requests will go to the aviation authority (AESA) and the air navigation provider (ENAIRE). A notice to airmen is published for each flight, and live GNSS tracking is shared throughout.
