Key highlights

The 8U CubeSat from EnduroSat is a flight-heritage nanosatellite platform that brings multi-payload capability to a compact form factor. The CubeSat bus offers 4U of available volume — a payload envelope of up to 96 x 210 x 222 mm — with 6.7–6.8 kg of available payload mass on a bus weighing 8.4–9.3 kg, configuration dependent. A redundant architecture lets operators fly several payloads on a single spacecraft and execute complex mission scenarios that would otherwise demand multiple launches.

Power and data budgets are sized well above typical nanosatellite expectations: average payload power of 13–40 W (configuration dependent) is distributed across 3.3 V, 5 V, 12 V, 28 V and battery-bus (14.7–17.5 V) rails, while payload downlink reaches up to 150 Mbps gross over S-band and X-band, with secure TMTC at up to 125 kbps full duplex. Payload control runs over standard CAN FD, RS-422, RS-485, UART and SPI interfaces, and an embedded operational-modes framework handles diverse payloads autonomously, supporting mission lifetimes of 3–5 years depending on orbit.

The satellite platform is adaptable to Earth observation, communications and scientific research missions, and is delivered mission-ready with an integration manual, software development kit, one-year SpaceDev subscription, complete bus and debugging cable sets and ten hours of engineering support. An optional advanced three-axis reaction wheel attitude control system is available for pointing-sensitive payloads, and EnduroSat's Space Service can take a customer payload from delivery to orbit within six months.

Applications

Earth observation missions in LEO
