A SOLID STATE PULSE MODULATED RADIOSONDE.
Abstract
The thesis is concerned with the design and construction of a radiosonde used in solid state devices and state-of-the-art techniques. The radiosonde is designed with the idea of obtaining data at a ground station in digital form and transmitting this data direct to Weather Central via high speed data links. Pulse modulation is used to transmit the data from the radiosonde. The multiplexer (time multiplexing is utilized) is designed using MOS micro technology and a breadboarded simulation is accomplished using discrete MOS integrated circuits. A computer simulation of the actual multiplexer design is performed. The modulator and transmitter are of complete solid state design. Extensive testing of the overall system indicated satisfactory results and show a substantial improvement over the present radiosonde. Modification of ground receiving systems to facilitate proper reception of information from the radiosonde is also discussed. (Author)
