The NPSAT1 mission, conceived and developed by
the Naval Postgraduate School (NPS) Space Systems
Academic Group (SSAG), is sponsored and executed
by the DoD Space Test Program (SMC SDD). The
small satellite is manifested for launch aboard the
STP-1 Atlas V Mission due to launch in December
2006. The main objective of the NPSAT1 program is
to provide educational opportunities for the offi cer
students in the Space Systems Curricula at NPS through
the design, testing, integration, and fl ight operations of
a small satellite. The 82 kg (180 lbs) satellite will be
earth-pointing using a novel, low-cost, 3-axis attitude
control scheme. NPSAT1 will provide a platform for a
number of spacecraft technology experiments, including
a lithium-ion battery, a confi gurable, fault-tolerant
processor (CFTP) experiment, and fl ight demonstrations
of commercial, off-the-shelf (COTS) components such
as microelectromechanical systems (MEMS) rate sensors
and a digital camera. The spacecraft command and data
handling (C&DH) subsystem is NPS-designed, featuring
low-power with error-detection-and-correction (EDAC)
memory, an ARM720T microprocessor, and running
Linux as the operating system. Two other experiments are
provided by the Naval Research Laboratory to investigate
ionospheric physics. This paper presents an overview of
the spacecraft, its subsystems, and the challenges of a small satellite program in a university environment.
