Rate aided ranging and time dissemination receiver

摘要: A receiver is described for processing tone ranging signals from a time dissemination satellite such as TIMATION II. The derives either receiver-station (clock synchronization) or position location of the with respect to significant accuracy. generates set range tones duplicates those received satellite. They are developed frequency coherent phase lock loop synchronized signal carrier frequency. second loop, having synthesizer locked mixer, narrow band amplifier and detector mix locally generated local oscillator which carrier. This mixer output then mixed modulation null out error between tones. An consisting lowest representative Coherent by mixing at front-end in preferred embodiment allows automatic calibration non-zero propagation delays, use IF amplifiers thereby effecting high levels unwanted rejection. synthesized continuous time-delay measurements even though not continuously transmitted.
