A SMALL SATELLITE FOR MEASURING ATMOSPHERIC WATER CONTENT; PART I, DOWNLINK AND COMMAND SYSTEMSCramer, J., Biggs, B., Contapay, J., Iskandar, A., Mahan, A. 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This student paper was produced as part of the team design competition in the University of Arizona course ECE 485, Radiowaves and Telemetry. It describes a telemetering system design recommendation for a small satellite capable of conducting scientific research regarding atmospheric water content. This paper focuses on the subsystems required to send the scientific data and monitored operational conditions from the satellite to, and commands to the satellite from, a ground station. A companion paper (Hittle, et. al.) focuses on the cross-link subsystem required to make the scientific measurements and on the power generation and distribution subsystem for the satellite.

A SMALL SATELLITE FOR MEASURING ATMOSPHERIC WATER CONTENT; PART II, CROSSLINK AND DATA COLLECTIONHittle, K., Braga, A., Ackerman, R., Afouni, F., Khalid, H., Coleman, J., Keena, T., Page, A. 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This student paper was produced as part of the team design competition in the University of Arizona course ECE 485, Radiowaves and Telemetry. It describes a telemetering system design recommendation for a small satellite capable of conducting scientific research regarding atmospheric water content. This paper focuses on the cross-link subsystem required to make the scientific measurements and on the power generation and distribution subsystem for the satellite. A companion paper (Cramer, et. al.) focuses on the subsystems required to send the scientific data and monitored operational conditions from the satellite to, and commands to the satellite from, a ground station. The central objective is to validate a new technique for precisely measuring water vapor profiles of clouds throughout the troposphere. This method involves the detection of 4 SHF tones sent out from the International Space Station (ISS), providing high-resolution amplitude and phase delay data.

TELEMETERING SYSTEM FOR THE UA SATELLITEHammond, C., Beauvarlet, D., Kipple, A., Condit, R., Firestone, T., Ling, V., Morris, G., Powers, D. 10 1900 (has links)
International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / This student paper was produced as part of the team design competition in the University of Arizona course ECE 485, Radiowaves and Telemetry. It presents a telemetering system proposed for UASat, a small satellite being designed for launch in the year 2004. The overall system architecture is described, including the transducers used by each subsystem, the command and telemetry packet formats, the antennas and modulation schemes, the link budget, and some hardware recommendations. A discussion of the data analysis is also included.

EYE IN THE SKY: AIRSHIP SURVEILLANCESullivan, Arthur, Turner, William C. 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The first airship was invented and designed in 1852 by Henri Giffard, a French
engineer. Airships were used by both the Allied and German military for surveillance
and bomb dropping in WWI. There was a steady increase in airship use up until the
Hindenburg exploded while docking in 1937 at Lakehurst, New Jersey. This tragedy
almost ended the use of airships. Significant use of airships next occurred during
WWII for submarine surveillance and depth charging. Airships for advertising,
surveillance, and command control came of age in the late 1980s and early 1990s.
Airships can be fitted with several telemetry options or instrumented with sensor
systems for surveillance purposes. The telemetry or sensor data can be relayed, real-time,
to a remote station as much as 150 km from the airship either encrypted or plain
when cruising at 3000 feet altitude. Small vehicles (3 meters long) can be detected at
50 km using radar; 12 km using FLIRs; and, depending on weather conditions and
real-time imaging processing, up to 20 km using video cameras. Cooperating airborne
targets can be tracked out to 150 km.
The major advantages of the airship over conventional aircraft are:
• ENDURANCE Up to 20 hours without refueling.
• LOW OPERATING COST Less than the cost of a helicopter.
• SHOCK-FREE ENVIRONMENT Allows commercial electric equipment usage.
• VIBRATION-FREE ENVIRONMENT Yields personnel comfort and endurance.
• SAFETY Safer than any aircraft, automobile, or bicycle.

INCA Cubesat: A Design Analysis of the Telemetering SystemBurgett, Taylor 10 1900 (has links)
ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV / The goal of this project is maximize the performance of the telemetering system for the INCA cubesat mission using what we are learning in class to develop tests to figure out the optimal selection of frame scheme, data rate, and modulation technique based on the requirements of the mission. This project will help me learn about different modulation techniques and give me real world experience testing a telemetry system. I will evaluate my results through a comparison of the error rates for the different modulation schemes and do statistical analysis to show the reliability of the data. The results will be useful to any future mission that implements the same satellite communication system including future missions at NMSU.
