Sierra Space Eclipse™ Satellites
Configurable spacecraft architectures for missile warning and tracking, space control, orbital mobility, logistics, and multi-orbit missions.
Overview
Spacecraft built around the mission
Sierra Space Eclipse™ satellites are tailored solutions for national security missions. The architecture combines configurable buses, payload accommodation, mission integration, and enabling technologies so different mission classes can be supported without starting from a clean sheet each time.
Comparison
Three platforms, one architecture
| Platform | Mission role | Platform character | Design focus |
|---|---|---|---|
| Horizon | Missile warning and tracking | Constellation spacecraft designed for repeatable production | Earth-facing RF and infrared sensor payloads |
| Velocity | Space control | Maneuverable spacecraft built around on-orbit responsiveness | Rendezvous, proximity operations and docking |
| Titan | Space mobility and logistics | Carrier platform designed to move and host other spacecraft | Last-mile delivery and refueling support |
Descriptions reflect platform design intent. Mission profiles, performance, and program detail are established with the customer.
Missile warning and tracking
Horizon
Horizon is designed for proliferated constellations, with accommodation for Earth-facing RF and infrared sensor payloads.
Space control
Velocity
Velocity is a maneuverable spacecraft with flexible payload and service capabilities, including rendezvous, proximity operations and docking.
Space mobility and logistics
Titan
Titan is a carrier platform designed for last-mile spacecraft delivery and refueling support.
Configuration
A configurable foundation
Customers engage Sierra Space around the mission environment, performance need, timeline, payload, and integration model.
- Mission-tailored configuration
- Payload accommodation
- Subsystem integration
- Test and qualification
- Production and mission support
Systems depth
Built with systems depth
Eclipse draws on capability across power, pointing and motion control, avionics, mechanisms, propulsion, thermal management, integration, and operations. That depth connects spacecraft decisions directly to mission performance.
