The development of the ANAMQ-21 Continuous Transmission Multichannel radiosonde for use with Rawin Set ANGMD-2 for meteorological soundings is described. Primary functions of the radiosonde are the measurement of slant range, temperature, humidity and the provision for using an index of refraction sensor. It is a balloon borne ground launched device, transmitting all data simultaneously on a standard radiosonde carrier frequency. The report includes design considerations, descriptions of the radiosonde electronic system, discussion of associated antenna development, results of environmental and flight tests, and recommendations for additional developmental work.
