CubeSat 3U Platform
IMT srl complete CubeSat 3U platform with 3-axis attitude control, VHF/UHF comms, 43 Wh Li-ion battery, AzurSpace GaAs solar panels, and FreeRTOS flight software for up to 5-year LEO missions.
Description
The IMT srl CubeSat 3U Platform is a compact, flight-ready satellite bus designed for science, Earth observation, and technology demonstration missions. Features redundant architecture and radiation mitigation by design, with an operational lifespan up to 5 years in LEO. Integrates a 43 Wh Li-ion battery (configurable as 4S/2S2P/4P), AzurSpace triple-junction GaAs solar panels at 30% efficiency providing 4W average body-mounted power, 3-axis attitude stabilization with 5deg knowledge and 10deg control, and VHF/UHF communications up to 9600 bps. Power buses of 3.3V and 5V at up to 5A each with latch-up protection, data interfaces via I2C, CAN, SPI, and UART, and 8 GB payload data storage round out the platform. Qualified to >15 kRad(Si) radiation tolerance with SEU mitigation and SEL protection.
