STPSat-1

STPSat-1, a Department of Defense (DoD) Space Test Program (STP) mission, was launched by an Atlas 5 rocket from Cape Canaveral on 9 March 2007. The satellite's two payloads, both designed and built by the Naval Research Laboratory (NRL), provided unique measurements of middle atmospheric hydroxyl, polar mesospheric clouds and the low latitude ionosphere. The primary experiment, Spatial Heterodyne Imager for Mesospheric Radicals (SHIMMER), is a high-resolution ultraviolet spectrometer based on the new optical technique known as Spatial Heterodyne Spectroscopy (SHS). SHS facilitates the design of low mass, low power, high throughput spectrometers for space-based remote sensing. The secondary experiment, the Computerized Ionospheric Tomography Receiver in Space (CITRIS), will investigate irregularities that affect propagation of satellite-to-ground links for GPS and communications.

STPSat-1，作为美国国防部（DoD）空间测试计划（STP）的使命，于2007年3月9日由一枚Atlas 5火箭从卡纳维拉尔角发射升空。该卫星搭载的两项有效载荷均由海军研究实验室（NRL）设计和制造，分别为中层大气羟基、极地中层云和低纬度电离层提供了独特的测量数据。主要实验——中层大气自由基空间外差成像仪（SHIMMER）——基于一种称为空间外差光谱学（SHS）的新光学技术，是一种高分辨率紫外光谱仪。SHS技术促进了低质量、低功耗、高吞吐量光谱仪的设计，适用于太空遥感。次要实验——太空计算机化电离层层析成像接收器（CITRIS）——将研究影响GPS和通信卫星至地面链路传播的异常情况。
