Products & Solutions
Space Service
An end-to-end mission service that takes customers from payload definition to operational data delivery at a fixed cost. EnduroSat handles mission analysis, satellite integration, launch coordination, commissioning and cloud-based operations, with customers receiving data via API. The service can get a mission to orbit in approximately six months.
FRAME Satellite Platforms
A family of modular small satellite platforms designed for serial production. FRAME-24 is a 24U-class microsatellite and FRAME-15 is an ESPA-class satellite in the 200-500 kg range, both built for constellation deployments. The platforms support remote sensing payloads including hyperspectral, multispectral, SAR, thermal and broadband connectivity applications.
CubeSat Platforms
Standardised 8U and 16U CubeSat buses with flight-heritage across dozens of missions. Designed as modular building blocks, they integrate with EnduroSat's own avionics modules or third-party payloads. A DeskSat flatsat variant is available for ground testing and development before flight.
Satellite Modules
A catalogue of individual satellite avionics and structural components sold separately: onboard computers, UHF/S-band/X-band radios, power systems, solar panels and CubeSat structures. Over 3,000 modules have been deployed in orbit across customer missions, with engineering support hours included.
