The computer was architecturally similar to the Saturn Launch Vehicle Digital Computer, in particular in the instruction set; [6] however its circuit integration was less advanced. [7] The GGC weighed 58.98 pounds (26.75 kg) and was powered by 28V DC. During a short power outage it could be powered by the Auxiliary Computer Power Unit (ACPU)
This delay resulted in an abnormal orbit and excessive fuel use. The decision was made to scratch the ISS rendezvous/docking since the spacecraft burned too much fuel to reach orbit even after Mission control center fixed the MET clock issue. NASA and Boeing officials placed the spacecraft in a different orbit and the entire flight plan had to ...
Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. [1]
Static timing analysis (STA) is a simulation method of computing the expected timing of a synchronous digital circuit without requiring a simulation of the full circuit. High-performance integrated circuits have traditionally been characterized by the clock frequency at which they operate.
A launch status check, also known as a "go/no go poll" and several other terms, occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed.
TRACE is a high-precision orbit determination and orbit propagation program. It was developed by The Aerospace Corporation in El Segundo, California. An early version ran on the IBM 7090 computer in 1964. [1] The Fortran source code can be compiled for any platform with a Fortran compiler.
Vandenberg Space Launch Complex 6 (SLC-6, pronounced "Slick Six") is a launch pad and associated support infrastructure at Vandenberg Space Force Base in California. Construction at the site began in 1966, but the first launch didn't occur until 1995 due to program cancellations and subsequent repurposing efforts.
Boeing modified the design of the Starliner docking system after the OFT-1 flight, adding a hinged re-entry cover below the expendable nosecone for additional protection during the capsule's fiery descent through the atmosphere similar to the one used in the SpaceX Dragon 2 nosecone. This was tested on the OFT-2 mission.
