LEO STAR  

Northrop Grumman's LEOStar-2 spacecraft is a compact, flexible, high performance platform for space and Earth scientific, remote sensing, and other applications. LEOStar-2 spacecraft have flown on Pegasus®, Minotaur and Delta II launch vehicles, are compatible with other U.S. and foreign launch vehicles including Falcon 9, Dnepr and Vega, and can be configured as an ESPA ride share. The platform is optimized for Low Earth Orbit missions and can be adapted to other missions (MEO, Lunar or Lagrange Points). The avionics architecture supports single-string or selective redundancy configurations. Using EEE-INST-002 level 2, level 3 or screened commercial parts LEOStar-2 is able to support 1 to 5 year on-orbit lifetimes with high reliability

Northrop Grumman's LEOStar-3 spacecraft is a high performance, versatile and expandable vehicle for space and Earth scientific, remote sensing, and commercial applications. LEOStar-3 spacecraft have flown on Pegasus®, Minotaur, Delta II and Atlas V launch vehicles, and are compatible with other launch vehicles such as Falcon 9 and Antares™. The platform is optimized for Low Earth Orbit missions and is readily adaptable to other missions (MEO, Lunar or Lagrange Points). The avionics architecture uses an open frame avionics structure with a cPCI backplane. Extensive Field Programmable Gate Arrays (FPGAs) use provides re-programmability and reduces EEE parts count. The avionics are available in single-string, selectively redundant or fully redundant configurations using EEE-INST-002 level 2 or level 3 parts.
