-2 Bus
Mission Services
Customers can procure the LEOStar-2 spacecraft bus alone
or as part of a “turn-key” service that includes mission design,
instrument/payload integration, satellite environmental test, launch
services, early orbit checkout, and mission operations, including
instrument data delivery to principal investigators. Orbital has the
end-to-end capability to build, integrate, test, launch and operate
missions.
Production Approach
Using mature designs, proven assembly procedures, and
established vendor sources, the LEOStar-2 bus can be developed
well within 36 months after receipt of order.
Heritage
Currently, Orbital has four LEOStar based satellites on-orbit
and has three in production. First developed for the GeoEye,
OrbView-3, and OrbView-4 commercial high-resolution imagery
system, the LEOStar-2 spacecraft has flown in a redundant
configuration for NASA’s SORCE mission, in a selectively
redundant configuration for NASA’s GALEX mission, and in a
single-string configuration for NASA's AIM and NuSTAR missions.
Currently LEOStar-2 programs include the OCO-2, TESS and
ICON spacecraft. Science applications include atmospheric
monitoring, solar irradiance monitoring, and astronomical
exploration. With appropriate modification, we have also adapted
this bus for JPL’s Dawn interplanetary mission, currently en route
to the asteroid Ceres.
Options
• Avionics components, actuators, or sensors to improve system
capability and increase mission reliability and lifetime
• Expanded on-board solid state memory and X-band downlink for
increased payload data storage and high rate data transfer
• Hydrazine propulsion capability to enable orbit maneuvers and
increase mission lifetime
• Spacecraft operations and data delivery
Additional Features
• Modular Design – Flexibility in design (ACS sensor and actuator
selection, payload unique data services), assembly, integration
and testing
• Low Cost with High Experience – As a world leader in developing
and manufacturing affordable mission solutions, Orbital can
deliver highly capable flight systems under tight cost and
schedule constraints
