Accelerate Deployment of Space
Missions Through Digitalization
Apply digital engineering techniques to reduce costs and
increase operational confidence
The Need for Speed
Huge paradigm shifts have occurred in the space industry over the last two
decades. After the initial space race of the 1950s and ’60s, the investment in
commercial space applications rested on the experiences of government agencies
that put humans on the moon and satellites into orbit. Through the ’60s and
into the mid-’70s, those agencies launched bent-pipe transceivers for television,
telephone, and fax signals alongside the first weather satellites.
Through the 1980s and mid-’90s, commercial satellite operations were dominantly
Global Navigation Satellite System, video broadcast, weather, telecommunications,
and global imaging. The costs associated with the launch and deployment of such
missions drove engineering choices that minimized risks, ensuring space durability
for 15 to 20 years or more to provide maximum return on investment. The use of
space-proven radiation-hard components was essential.
Large satellites with backup systems in medium Earth orbit and geosynchronous
equatorial orbit provided global coverage. The largest of these satellites could weigh
several tons on the Earth’s surface.
Digital Engineering
The US Department of
Defense defines digital
engineering as an inte-
grated digital approach
that uses authoritative
sources of system data
and models as a contin-
uum across disciplines to
support life cycle activities
from concept to disposal.
