APL 已为 NASA 计划中的冥王星和柯伊伯带新地平线任务开发了一种低功耗 X 波段数字上行链路接收器，该任务计划于 2006 年 1 月发射，最早于 2015 年与冥王星相遇。该上行链路接收器提供 X 波段载波跟踪、命令检测/解调、关键命令解码、测距音调解调和内置辐射测量模式。主要射频载波跟踪、命令检测和测距要求与之前的深空射频系统类似，包括小型深空转发器 (SDST) 和 CONTOUR 射频收发器系统。放射科学兼容性和降低功耗的额外设计要求催生了一种新的设计方法。新的接收机设计利用数字处理技术和改进的系统架构来满足这些新要求，同时比以前的系统增强了性能和灵活性。与同类前代系统相比，二次功耗降低了 53% 至 68%。本文详细描述了新型低功耗数字接收器设计。
A low-power X-band digital uplink receiver has been developed by the APL for NASA's planned New Horizons mission to Pluto and the Kuiper Belt, which is scheduled to launch in January 2006 with a Pluto encounter as early as 2015. The uplink receiver provides X-band carrier tracking, command detection/demodulation, critical command decoding, ranging tone demodulation, and built-in radiometrics modes. The primary RF carrier tracking, command detection, and ranging requirements are similar to those of predecessor deep space RF systems, including both the small deep space transponder (SDST) and CONTOUR RF transceiver systems. Additional design requirements for radioscience compatibility and reduced power consumption led to a new design approach. The new receiver design makes use of digital processing techniques and revised system architecture to meet these new requirements, while at the same time enhancing performance and flexibility over predecessor systems. A 53% to 68% reduction in secondary power consumption over comparable predecessor systems has been achieved. This paper provides a detailed description of the new low-power digital receiver design.
