Lessons Learned From The Miniature Sensor Technology Integration (Msti) -3 Controlled Reentry, Lesley Rahman, Preston Diamond, Todd Probert

Small Satellite Conference

This paper is presented as an overview of the lessons learned from the controlled reentry of the Air Force Miniature Sensor Technology Integration program's third satellite (MSTI-3). Since the launch of Sputnik in 1957, the amount of space debris in orbit has progressively increased to potentially hazardous levels. In light of these facts, the National Space Policy directs the United States to minimize the creation of space debris. NASA has already adopted a policy to limit the generation of orbital debris, and DoD policy has supported debris minimization for well over a decade. The MSTI-3 spacecraft was neither designed, nor …

Precision Control, Knowledge And Orbit Determination On A Small Spacecraft Bus: The Orbview-4 Attitutde Control System, Dewey Adams, Dominick Bruno, Piyush Shah, Brian Keller

Small Satellite Conference

High resolution, Earth imaging missions place stringent requirements on the spacecraft Attitude Control System (ACS) in terms of pointing accuracy, attitude knowledge, and orbit knowledge. For OrbView-4, a body scanner, the spacecraft must also be agile to maximize the number of targets that can be imaged each orbit. These requirements dictate a robust, high performance design that allows rapid target acquisition and high line scan rates for mapping while maintaining precise knowledge and control of the camera line of sight vector. The OrbView-4 ACS combines state of the art components with robust algorithm design to meet these objectives. Equipment selection, …

Investigation Of Propulsion System Requirements For Spartan Lite, Michael Urban, Timothy Gruner, James Morrissey, Gary Sneiderman

Small Satellite Conference

This paper discusses the (chemical or electric) propulsion system requirements necessary to increase the Spartan Lite science mission lifetime to over a year. Spartan Lite is an extremely low-cost (< $10M) spacecraft bus being developed at the NASA Goddard Space Flight Center to accommodate sounding rocket class (40 W, 45 kg, 35cm dia by 1 m length) payloads. While Spartan Lite is compatible with expendable launch vehicles, most missions are expected to be tertiary payloads deployed by the Space Shuttle. To achieve a one year or longer mission life from typical Shuttle orbits, some form of propulsion system is required. Chemical propulsion systems (characterized by high thrust impulsive maneuvers) and electrical propulsion systems (characterized by low-thrust long duration maneuvers and the additional requirement for electrical power) are discussed. The performance of the Spartan Lite attitude control system in the presence of large disturbance torques is evaluated using the Treetops dynamic simulator. This paper discusses the performance goals and resource constraints for candidate Spartan Lite propulsion systems and uses them to specify quantitative requirements against which the systems are evaluated.

The Software Design For The Wide-Field Infrared Explorer Attitude Control System, Kenneth Barnes, Charles Melhorn, Tom Phillips

Small Satellite Conference

The Wide-Field Infrared Explorer (WIRE), currently scheduled for launch in September 1998, is the fifth spacecraft in NASA's Small Explorer (SMEX) series. WIRE's mission is to perform a four month survey of galaxies with unusually high star formation rates ("starburst galaxies"). It is a momentum-biased three-axis stabilized stellar pointer which provides high-accuracy pointing and autonomous acquisition for eight to ten targets per orbit. Much of the design is based on previous SMEX missions, WIRE's short mission life and limited cryogen supply impose strict new Sun and Earth avoidance requirements which protect the instrument and preserve cryogen. This paper presents the …

Project Spartnik: Microsatellite Design, Construction, Testing, And Operation By Undergraduate Students At San Jose State University, Jeffrey Lin, Francisco Soriano, Michelle Schoenman

Small Satellite Conference

Spartnik is a microsatellite under construction at San Jose State University. Three distinct payloads are being designed, fabricated, tested, and integrated by students solely at the undergraduate level. These payloads consist of a digital color camera, a Micro-Meteorite Impact Detector, and a fairly sophisticated communications package that transmits and receives data on the amateur radio frequency band. As part of a year-long senior design project, students are distributed into seven separate subsystems in which they learn about the design and construction of their specific components and how they interact in a satellite as a whole. Significant progress has been made …

Smaller Than Small, Faster Than Fast, Cheaper Than Cheap: The Barnacle Satellite Project, John O'Boyle, Iii, Pascal Stang, Nick Woods

Small Satellite Conference

The BARNACLE micro-satellite is an extremely simple low-cost space vehicle for the characterization of electronic instruments in space. The satellite was developed in less than one year by a group of seven undergraduate engineering students with no previous spacecraft design experience. The satellite was built for under $2,000 of the students own money with most of the hardware donated by industry and university sponsors. The craft includes a Motorola 68HC11 microprocessor-based subsystem for system control, with a logic system to back up the processor in the case of failure. Power is regulated by high-efficiency switching mode regulators in the power …

A Small/Micro-/Pico- Satellite Program For Investigating Thunderstorm-Related Atmospheric Phenomena, Christopher Kitts

Small Satellite Conference

A low cost, multi-satellite program for conducting novel atmospheric science is described. The program exploits simple visual and radio frequency sensing in order to investigate atmospheric phenomena induced by thunderstorms. The science instrumentation is supported by a variety of standalone and collaborative small, micro-, and picosatellite vehicles in order to meet the program's science requirements while also exploring a spectrum of small satellite approaches for conducting meaningful science. This multi-mission program is being developed jointly by student design teams at Stanford University and Santa Clara University.

Nasa-Gsfc Nano-Satellite Technology Development, Peter Panetta, Harry Culver, John Gagosian, Michael Johnson, James Kellogg, David Mangus, Theodore Michalek, Victor Sank, Steven Tompkins

Small Satellite Conference

The scientific understanding of key physical processes between the Sun and Earth require simultaneous measurements from many vantage points in space. Nano-satellite technologies will enable a class of constellation missions for the NASA Space Science Sun-Earth Connections theme. These technologies will also be of great benefit to other NASA science enterprises. Each nano-satellite will weigh a maximum of 10 kg including the propellant mass. Provisions for orbital maneuvers as well as attitude control, multiple sensors and instruments, and full autonomy will yield a highly capable miniaturized satellite. All onboard electronics will survive a total radiation dose rate of 100 krads …

Techsat 21 - Space Missions Using Collaborating Constellations Of Satellites, Alok Das, Richard Cobb

Small Satellite Conference

New technologies for power systems, electronics, micro-electro-mechanical systems, structures, and payloads are enabling significant reduction in the size, cost, and weight of satellites. It is estimated that satellites supplying 1 kW prime power with 1 GFLOP processing capability can be mass-produced at less than 100 kg in the near future. These capable, lightweight, low cost micro-satellites open up new vistas for space system architectures. Concepts are presented which distribute the function of a satellite to a cluster of such micro-satellites flying in formation. It is shown that simply subdividing a satellite into smaller pieces does not in itself offer more …

York, Robert Oral History Interview, Stuart O'Brien

Edmund S. Muskie Oral History Collection

Robert Maurice York was born on June 10, 1915 in Wilton, Maine. His parents were Josephine Myra (Brown) and Maurice Asa York. His father owned a meat market in Wilton, and his mother was a homemaker. York went to Bates College, graduating in the class of 1937. He then went on to Clark University to get his Masters and Ph.D. in History. After graduating, he enlisted in the Navy, and saw active duty in the Pacific. Japanese Kamikaze planes sunk the boat he originally served on, so he returned stateside and worked for the Office of Naval History. In 1946, …
