Meteor Space Vehicle Bus
Medium Class Spacecraft Bus
METEOR is a Medium Class Spacecraft Bus product family used for a variety of missions in LEO including High LEO (1000 to 1200 km). METEOR is ideal for pathfinder constellation missions or other disaggregated mission types. METEOR leverages the same core avionics from Moog’s Space Vehicle family that have been demonstrated in missions from LEO to the Moon. The hydrazine propulsion system provides enough capability for a controlled deorbit from High LEO. The relatively high thrust can be used for collision avoidance or other rapid orbit changes. The simple and robust all aluminum structure derived from Moog’s ESPA provides radiation shielding and can support a range of payload configurations.
Key Features:
- Avionics leveraging Moog’s BRE440™ Rad-Hard CPU
- LEO up to 1200 km with 2-5 year life
- Flexible flight software is payload and mission configurable
- High-thrust hydrazine propulsion system
- 3-Axis stabilized platform with reaction wheels and torque rods
- Single string but layered GNC sensor suite provides resiliency
- Modular power system can be expanded as needed
- Can be stacked or dual launch in NSSL-class launch vehicles
