- W2012326933 abstract "The development of a prototype lunar transponder for Air Force Cambridge Research Laboratories by General Dynamics/Astronautics demonstrates the feasibility of designing future transponders for hard landings on the moon. Table 1 provides some of the design characteristics of the prototype transponder. Advanced solid-state circuitry, stripline microwave techniques, and special environmental packaging were used in its design [General Dynamics/Astronautics, 1963]. Figure 1 shows an expanded view of the prototype I lunar transponder components. On the moon the transponder functions essentially as a frequency-modulated transceiver, which receives a 5052-Mc/s carrier frequency from an earth-based tracking system. The carrier frequency is modulated by a 4-kc/s range measurement signal, which is retransmitted through the same transponder directional antenna on a nominal 5000-Mc/s carrier frequency to the earth-based tracking system. Also, a course modulation frequency of 160 cps is used for ambiguity resolution in the range measurement determination. The voltage-controlled oscillator and the phase detector form a phase-lock loop, which has sufficient bandwidth for retransmission of the range measurement signal." @default.
