Space Platform 500

• Purpose: Design and manufacture of small spacecraft for technological scientific purposes, communications, remote sensing for operation in various types of orbits – from low circular to geostationary.
• Year of release: 2017
• Guaranteed service life (years): Active life (SAS) - 5 years for remote sensing of the Earth (ERS), 10 years for small spacecraft (ICA) communication (with bringing SAS up to 15 years).
• Estimated production / delivery time (months): 18
• Flight qualification of the product: No
• Brief history of flight qualification: Most of the modules of the platform system, including the onboard control system and the orientation and stabilization system, are composed of previously developed and flight-qualified devices and equipment, which makes the platform even cheaper and more attractive by minimizing risks.
• Possibility to adapt the product to customer requirements: Yes

Platform for small spacecraft weighing up to 700 kg. Height of operation on different types of orbits – from low circular to geostationary. The ICA platform is divided into several independent modules. Each module separately is a subsystem of the platform and is a functionally and structurally separate unit, which has clearly defined mechanical, electrical and thermal interfaces.

Peculiar properties:

• untight;
• battery: Nickel-hydrogen for the ICA remote sensing; Li-ion for the ICA connection;
• passive thermal control system on heat pipes and heaters;
• system of orientation and stabilization on the basis of the star sensors and control engines-flywheels;
• maintaining the orbit parameters is carried out by the correction system based on the thermocatalytic propulsion system (hydrazine) for the remote sensing spacecraft, the electric propulsion system (xenon) for the communication spacecraft.

Remark

Stage of development: Manufactured tooling for the Assembly of the platform and the ICA on its basis. The layout of the platform was made and the layout of the platform and the ICA (remote sensing and communication) was carried out on its basis. Made layout for dynamic and acoustic tests. Mechanical and acoustic tests of the platform were successfully carried out. All parameters and characteristics of the platform are confirmed.
