The following examples show natural language CSTOL commands and the lower-level spacecraft commands they are translated into, for a particular spacecraft. [5] The first two examples show two different CSTOL commands that are translated into the same spacecraft command, indicating that this spacecraft command takes different values as an argument.
The Power of 10 Rules were created in 2006 by Gerard J. Holzmann of the NASA/JPL Laboratory for Reliable Software. [1] The rules are intended to eliminate certain C coding practices that make code difficult to review or statically analyze.
However, the design concept surpassed the technological capabilities of the time, leading to the cancellation of the program in May 1962. The Initial Defense Communications Satellite Program (IDCSP) was proposed as one of two recommended follow-up approaches to deliver a working satellite. Philco (now Ford Aerospace) was contracted for the work.

SatNOGS (Satellite Networked Open Ground Station) project is a free software and open source hardware platform aimed to create a satellite ground station network. The scope of the project is to create a full stack of open technologies based on open standards, and the construction of a full ground station as a showcase of the stack.
Astronauts manually flew Project Gemini with control sticks, but computers flew most of Project Apollo except briefly during lunar landings. [6] Each Moon flight carried two AGCs, one each in the command module and the Apollo Lunar Module, with the exception of Apollo 7 which was an Earth orbit mission and Apollo 8 which did not need a lunar module for its lunar orbit mission.
Commands may be issued manually in real time, or they may be part of automated or semi-automated procedures uploaded in their entirety. [7]: 485 Typically, commands successfully received by the spacecraft are acknowledged in telemetry, [7]: 485 and a command counter is maintained on the spacecraft and at the ground to ensure synchronization.
The U.S. Navy's Communications Satellite Program Office (PMW 146) of the Program Executive Office (PEO) for Space Systems in San Diego, is lead developer for the MUOS program. [4] Lockheed Martin Space is the prime system contractor and satellite designer for MUOS under U.S. Navy Contract N00039-04-C-2009, which was announced on 24 September 2004.
