Telemetry - An economical approach
Abstract
Remote piloted vehicle projects used for low-Reynolds-number testing have a need for high-resolution low-cost multichannel telemetry. Two approaches are discussed in detail in this paper. The first utilizes an analog 8 or 16 input multiplexer, feeding a single analog to digital converter. Disregarding RF transmitter and receiver, the manufactured cost would be about 21 dollars per data channel. The transmit section of the 96 channel unit could be housed in 52 cubic inches. The second system contains voltage controlled oscillators, transmitted to frequency to voltage converters. This system has good resolution, but has storage difficulties and often is limited in channel capability. For applications needing less than 15 channels, this system could be manufactured for 300 dollars. The coding or transmitter part would require less than 6 cubic inches for 15 channels.
