Abstract:

The results of a program to develop, design and fabricate a low-level telemetry subsystem to operate in the lower 1,000 meters of the atmosphere and compatibily interface with a modified Rawin Set ANGMD-4 is presented herein. The subsystem has been designed to provide a detailed analysis of the temperature, humidity and wind structure of the lower atmosphere, employing standard radiosonde sensors and transponder techniques, and consideration has been given for the use of modular construction to facilitate updating as new techniques and equipments are developed. The telemetry device is adaptable for use as a balloonsonde designed for data acquisition on ascent, or as a rocketsonde providing data acquisition on descent, upon deployment of a parachute and a sensor mounting package. Utilized in the design of this telemetry device are a solid state and integrated circuit commutator, with a sampling rate of one cycle per second, and a solid state microwave transmitter. The relatively high sampling rate of one every second provides a more complete synopsis of the atmospheric construction than have previous balloon borne or rocket sounding telemetry devices.
