Jet Propulsion Laboratory International Telemetering Conference Proceedings / October 10-12, 1972 / International Hotel, Los Angeles, California Third-order phase-locked receivers have not yet found wide application in deep-space communications systems because the second-order systems now used have performed adequately on past spacecraft missions. However, a survey of the doppler profiles for future missions shows that an unaided second-order loop may be unable to perform within reasonable error bounds. This article discusses the characteristics of a simple third-order extension to present second-order systems that not only extends doppler -tracking capability, but widens the pull-in range and decreases pull-in time as well. 1972-10 text Proceedings 0884-5123 0074-9079 http://hdl.handle.net/10150/605301 http://arizona.openrepository.com/arizona/handle/10150/605301 International Telemetering Conference Proceedings en_US http://www.telemetry.org/ Copyright © International Foundation for Telemetering International Foundation for Telemetering
