It’s Not Your Father’s Oldsmobile
In 1988, General Motors launched a rare anti-branding campaign that sought to
dispel the impression that Oldsmobiles were ‘stodgy box-m
obiles’
•Oldsmobile’s intent was to reinve
nt itself for yo
unger drive
rs and distanceitself from eve
rything for
which it had previously stood
–Hence
the "Not yo
ur father's O
ldsm
obile" slogan was born as a clear attempt to put the shine back in
the brand
•The ad campaign faile
d –
The problems with it, of course, were:
–It said what Olds wasn't, but not what it was, and
–It m
ore or less told a generation of Olds loya
lists that their previous car choice was an
embarrassment
•Net effect was not reinventing the O
lds brand identity but of carving the identity in stone

In their Heyday
During the period of their greatest vigor, strength, and successOldsmobile
epitomized achievement in distinctly middle-class term
s—a high-quality
car, but nothing so snooty as a Cadillac
Over time, the expression, “Not Your Father’s Oldsmobile”has come to
characterize product offerings that are new, different and better than
whatever came before them
For many reasons, 21stcentury remote sensing microsatellites are not your
father’s remote sensing satellites
Rather, they provide new, different and sometimes better solutions to a
user’s needs
Lest we replicate the failed Oldsmobile campaign, we need to define
•What a small or micro remote sensing satellite is;
•What it can and m
ore importantly cannot do;
•What are the features and benefits of these spacecraft;
•What are the differences in how small remote sensing satellites are developed, and
•Why the loya
lists of 1970 and 1980 vintage remote sensing systems should consider
using them for 21stcentury imaging m
issions

New Era of Remote Sensing Satellites
The Turn of the Century Marked a New Era of Remote Sensing Satellites
•Both NASA and the U.S. DoD embarked on new visions for smalle
r space systems
NASA
•Created the New M
illennium Program (NMP) with a stated goal to m
ake future
operational spacecraft "faster, cheaper and better" through incorporation of the
technologies validated in that program
•The Earth O
bserver-1 m
ission (the first NMP Flig
ht) was created to flig
ht-validate
advanced technologies for the next generation Earth Science Enterprise science needs
DoD
•U.S. National policy requires an ability to “augment space-based capabilities in a tim
ely
mannerin the event of increased operational needs or [to] minim
ize disruptions due to
on-orbit satellite failures, launch failures, or delib
erate actionsagainst U.S. space
assets
[1] .”
•The O
perationally Responsive Space (ORS) approach to building satellites represents a
new paradigm for the aerospace community and will impact future development
programs to provide operational responsiveness within the tim
eframe of a m
ajor national
emergency and provide direct connectivity to the warfighter in the theater of operations

ATK has Been at the Forefront of NMP and ORS
This Paper reviews Major design implementation differences between
legacy systems and these new, smaller remote sensing systems
This paper highlights and contrasts…
•The traditional risk averse approach to space, where it is required and where
adjustm
ents are acceptable to achieve contemporary system goals & objectives
•Key perform
ance m
etrics of current remote sensing small satellites such as power, data
throughput, agility, mass and volume with emphasis on the technologies that enable
higher perform
ance in today’s small buses
•Insight is provided on innovative adaptations of terrestrial andother non-traditional flight
technologies and reuse of existing technology to achieve rapid design, and assembly,
integration and test while
maintaining aggressive perform
ance requirements
ATK’s Responsive Space Modular Bus Program Reflects a rapid design and
production process for highly capable satellite buses to meet the stressing
development requirements of today’s world
