About
The EXA KRATOS 1U Spacecraft bus is a comprehensive 1-step CubeSat solution, providing everything needed for a spacecraft to operate. It is delivered VTV tested, requiring only payload integration before flight. The platform is highly configurable, ranging from a standard CubeSat to a powerful SpaceTaxi in a 1U form factor. It can host up to 6 standard payload boards and 3 cameras, delivering up to 100W of power. The platform also features LASER communications with a minimum speed of 10Mbps. Key components include an onboard computer with pre-installed libraries, an SDR Radio with an integrated power amplifier, a powerful EPS with 4 power rails, UMPPT Solar management coupled with a fast battery charger, and Deployable Multifunction Solar Arrays. It also includes automated deploy/release control for up to 4 devices, embedded monopole and dipole antennas covering VHF to L band, embedded magnetorquers, temperature and sun sensors on all walls, ADCS control with an integrated Z-axis magnetorquer, high-power batteries, and radiation-hardened SSD storage. The platform offers flexibility to add or subtract features and expand capabilities based on project budget, allowing users to concentrate on their mission while the platform handles the spacecraft’s complexities.
