Software Defined Radio System For Cubesat Communication, Tyler Gardner

Undergraduate Honors Capstone Projects

Cube satellites, or CubeSats, are small satellites designed around a base unit cube of 10 cm by 10 cm by 10 cm which is commonly referred to as a one unit, or 1 U, CubeSat. The modular architecture of CubeSats allows multiple 1 U frames to be stacked together to form a larger (1.5U, 2U, usually up to 6U) frame as needed. Because CubeSats are cheaper to develop and deploy in orbit than larger satellites, they have become increasingly common for academic, amateur, commercial, and scientific applications over the past five to ten years. There is potential that CubeSats will …

Software Defined Radio For Cubesat Communication, Sarah Watkins

Undergraduate Honors Capstone Projects

Cube satellites, more commonly referred to as CubeSats, are small satellites that have become increasingly popular for academic, amateur, commercial, and scientific applications over the past five to ten years. These satellites provide a fairly inexpensive and compact platform for deploying many different types of equipment. While CubeSats do not allow for housing large, complex instruments, some organizations have begun to explore the possibility of deploying networks, or clusters, of CubeSats. Satellites in these clusters could theoretically be tied together via radio frequency communications to accomplish more than a single CubeSat could alone.

This report summarizes the preliminary design and …

Cr9000 Measurement And Control System Pcmcia-Ata Software Device Interface, Ryan Jon Soulier

Undergraduate Honors Capstone Projects

Many industries have a need for high speed data collection of a large amount of data. For example, the auto industry extensively tests vehicles for resistance to stress, temperature, and moisture. Campbell Scientific, Inc. (CSI) has built the CR9000 measurement and control system that fills this need by being able to measure up to 252 separate sensors at a sustained rate of up to ten thousand samples per second.

The CR9000 system lacks efficiency because it has only a small, fixed amount of memory and is capable of recording data only for a short period. Older devices designed by CSI …

A Generalized Data Conversion System, Kevan Morgan

Undergraduate Honors Capstone Projects

To assist in the processing of data files collected by the Space Dynamics Laboratory at Utah State University, the software project GENDACS has been completed. GENDACS, acronym for A Generalized Data Conversion System, will contribute to its research program.

Data are collected from various sensory instruments by the Computer Data Acquisition System. The instrument readings are brought in, tagged with the time they were taken, and stored on an optical disk in a compact, binary (non-ASCII) format. GENDACS is designed so that the program can read in such files, sort out the data, and convert them into a new ASCII …
