Heritage:
First mission based on Seagull 1.0 platform on order, launch planned for Q4 2027
The largest and most power-capable HyperSat platform, a full-plate minisatellite built around SAR and other high-power, high-data-rate payloads. Designed for SAR Earth Observation, RF signal intelligence, connectivity and in-orbit servicing missions. Gen 1.0 in development now, first flight planned for Q4 2027.Why HyperSat Seagull?Very large payload bay: up to 140 kg of integrated instruments in an ESPA-class, full plate satellite.Built for power-demanding payloads: power and thermal subsystems and interface sized for e.g. SAR or communication instruments, with full avionics redundancy for long-duration operations.Exemplary use cases: Very High Resolution (VHR) SAR Earth Observation, Internet of Things, Direct-to-Device communications, Radio Frequency Signal Intelligence.
