Spacecraft buses and platforms.

Technologies

• Smallsat and CubeSat platforms Standardised small spacecraft (1U to ESPA-class) that lower the cost of hosted sensing and communications missions.
• Electrical power subsystems Solar arrays, batteries and power conditioning sized to payload duty cycle, eclipse and end-of-life degradation.
• Attitude and orbit control Sensors, reaction wheels, magnetorquers and control software that point payloads and antennas within budget.
• Propulsion (chemical, electric, low-toxicity) Thrusters for orbit raising, station keeping, collision avoidance and controlled disposal.
• On-board data handling and avionics buses Flight computers, mass memory and data buses that move payload data and commands inside the spacecraft.
• Thermal control and structures Radiators, heaters, insulation and primary structure that keep payloads in range through launch loads and orbit.
• Radiation effects and EEE parts Total dose, single-event and displacement analysis plus parts selection that sets mission life and reliability.
• Environmental verification Vibration, shock, thermal-vacuum and EMC test campaigns that qualify flight hardware before launch.
• Flight software and software-defined satellites Reconfigurable on-board software and processors that let missions change waveforms, beams or processing after launch.
