4、cs and Astronautics Approved 3 June 2016 Abstract This standard is an AIAA mandatory 5 year review version of the original AIAA S-117-2010. This updated version continues to be intended for commercial/noncommercial manned or unmanned space programs to achieve a key Mission Assurance goal of “Robust

Finally, this verification standard facilitates the closely coordinated verification and

These IFs are in general defined through inte

Subsequently, interface control documents (ICDs) that capture more detailed technical requirements will be established in order to design and develop systems that satisfy these requirements. Gro

They perform these functions using operational control nodes, satellite operations centers, geographically dispersed remote tracking stations/terminals, antennas, and networks to connect the many elements.

However,
