本文阐述开发小卫星技术的必要性,该技术将使小卫星有能力完成大卫星的飞行任务。韦伯州立大学(WSU)的空间技术中心(CAST)在小卫星的研制上具有18年的历史,曾经开发完成的卫星包括NUSAT、WEBERSAT和PHASE 3d。目前,CAST正在生产两颗新的具有先进功能的小卫星:USRA计划的CATSAT卫星将确定γ射线爆发的原因,这是与新罕布什尔大学和英国的Leicister大学的合作项目;JAWSAT卫星是与美国空军学院的合作项目,它将是用改装后的“民兵”导弹发射的第一个有效载荷。这两次飞行任务都需要达到同类卫星中前所未有的主动姿态确定与控制能力。为了支持这两次飞行任务,CAST承担了专为小卫星设计的卫星设备的开发研制工作。在其设计原则中将综合考虑尺寸、重量、功耗和成本最小。新的带动技术包括使用状态量采样网络进行敏感器总装、姿态确定和控制。整个研制过程将始终强调可靠性与验收试验。
This article describes the need to develop small satellite technologies that will enable small satellites to perform their mission on the satellite. The Space Technology Center at Weber State University (WSU) has 18 years of experience in the development of small satellites including NUSAT, WEBERSAT and PHASE 3d. Currently, CAST is producing two new satellites with advanced capabilities: The USRA-planned CATSAT satellite will determine the cause of the gamma-ray explosion, in cooperation with New Hampshire University and Leicister University in the United Kingdom; the JAWSAT satellite, It will be the first payload to be launched with a modified “militia” missile. Both missions require unprecedented proactive attitude determination and control in their class. In support of these two missions, CAST undertook the development of satellite equipment designed specifically for small satellites. In its design principles will be taken into account the size, weight, power consumption and cost minimum. New drive technologies include the use of state-level sampling networks for sensor assembly, attitude determination and control. The entire development process will always emphasize reliability and acceptance testing.
