A DISTRIBUTED, LOW-POWER TELEMETRY SYSTEM FOR SOLAR RACE CAR APPLICATIONS

Tuomey, E. S., Velasquez, G., Slade, S., Bunker, K., Reyes, E., Yousefnejad, T. 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 describes the design of a telemetry system for the University of Arizona’s Daedalus solar car. This is a distributed, low-power, telemetry-on-demand system that solves many of the problems typically encountered in this specialized telemetry application. The topology of the distributed microcontroller system is shown, as are optimal command and data packet structures. Also featured is a high-gain, low profile antenna system designed specifically for the solar car. Additionally, a customized chase car operator interface is illustrated.

DESIGN OF A SNOW AVALANCHE TELEMETRY SYSTEM

Lim, C., Hardie, S., Lyness, A., McMillan, S., Ung, L., Yu, V. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper was prepared as part of the team design competition for a graduate level course given at the University of Canterbury, in Christchurch, New Zealand. It presents a high level design of a snow avalanche telemetry system. The goal of the system is to provide data to better assess avalanche risk, and to assist in designing more effective protection measures in avalanche prone areas. The primary conditions monitored are air pressure, snow density, snow depth, snow temperature, wind velocity, wind direction, and ambient air temperature. All critical aspects of the telemetering system have been specified, including the sensors, transmitter/receiver, and telemetry frame design. Aspects of the system packaging and the link budget which are unique to the alpine environment are discussed.

A SMALL SATELLITE FOR MEASURING ATMOSPHERIC WATER CONTENT; PART I, DOWNLINK AND COMMAND SYSTEMS

Cramer, 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 COLLECTION

Hittle, 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.
