This is a short term (less than one-year) effort to develop and implement an accurate operational attitude determination algorithm for the NSF Dynamic Ionosphere CubeSat Experiment (DICE) space weather mission. It will support the development of required software modules as well as continued operation of the two DICE satellites. Completion of the software modules will result in corrected calibrated electron density and temperature data from the Langmuir Probes onboard the satellites. More importantly, it will also enable an operational capability to retrieve the satellite attitude information so that both satellites can be reliably steered into the appropriate orientation for the E-field booms to be successfully deployed. This, in turn, will enable E-field measurements to be obtained, and the full science mission to be completed.The tasks will be carried out as a collaborative effort between scientists and engineers at Utah State University (USU), Atmospheric & Space Tech Research Associates, and Embry-Riddle Aeronautical University (ERAU). The project will promote education and learning by involving students at USU and ERAU in both the satellite operations and data analysis tasks.The Dynamic Ionosphere Cubesat Experiment (DICE) is one of the first NSF Cubesat missions to be selected and flown. The DICE project consists of two CubeSats, weighing less than 2.2 kg each, which were launched into a highly eccentric low Earth orbit on October 28, 2011. Together the DICE CubeSats measure gradients of electric fields and electron densities in the ionosphere. The main science goal of the DICE project is to study the causes of storm enhanced densities (SED), which is a major space weather disturbance and concern.

这是一项短期（不到一年）的工作，旨在为NSF动态电离层立方体卫星实验（DICE）空间气象任务开发和实施精确的操作姿态确定算法。它将支持所需软件模块的开发以及两颗DICE卫星的继续运行。软件模块的完成将导致卫星上的Langmuir探测器的校正校准电子密度和温度数据。更重要的是，它还将具备检索卫星姿态信息的作战能力，以便两颗卫星都能可靠地引导到适当的方向，从而成功部署E-field弹幕。反过来，这将使电磁场测量能够获得，并完成完整的科学任务。这些任务将由犹他州立大学（USU）、大气与空间技术研究协会和安柏瑞德航空大学（ERAU）的科学家和工程师共同完成。该项目将通过让南苏丹大学和欧洲研究联盟的学生参与卫星业务和数据分析任务来促进教育和学习。动态电离层立方体卫星实验（DICE）是美国国家科学基金会首批选择和飞行的立方体卫星任务之一。DICE项目由两颗立方体卫星组成，每颗重量不到2.2公斤，于2011年10月28日发射到一个高度偏心的近地轨道。DICE立方体卫星一起测量电离层中的电场梯度和电子密度。DICE项目的主要科学目标是研究风暴增强密度（SED）的原因，这是一种主要的空间天气干扰和关注。
