The site is supported by the Department of Defense in partnership with the NSF REU program.Software development for mission and safety critical systems is critical to the United States economy, national security, and growth. The use of appropriate design, development and testing techniques is particularly important when a system must sustain human life or has the capability to injure humans through mal-operation. This REU experience makes students aware of and begins to get them used to designing, programming, debugging and testing for reliability. Even if students do not end up working professionally on or researching mission critical systems, these same techniques can help prevent software errors which may cause mal-operation or leave the software susceptible to attack and compromise.This REU Site introduces students to the design criteria of mission critical systems. They are gaining hands-on experience working on a real mission-critical cyber-physical system and gaining an appreciation of the importance of design processes. The participating students will visit the nearby Stanley R. Mickelsen Safeguard Complex, Missile Launch Area (home to the United States but now deactivated, anti-ballistic missile defense system). The participants will be involved in the design of an Open-Source/Open-hardware CubeSat class satellite (Open Orbiter) that has been under development at University of North Dakota (UND). Open Orbiter (OPEN) is a student led effort that is building up the full spectrum of systems required to develop, launch, and manage a CubeSat space mission. In order to test the variety of systems required and provide the participants with hands-on experience of conducting a real mission, the PIs are conducting one launch per year of an Open Orbiter prototype on a solar balloon. This includes the preparation and testing of the prototype, the launch, the recovery operation, and the post mission debriefing. Participants play key roles in all of these aspects. As Open Orbiter uses a Raspberry Pi and four Gumstix computers for the on-board processing, multithreaded programming/parallel programming is required to manage the satellite. In fact, the Open Orbiter system requires development in all areas of computer science, control software (operating system), ground station software and graphics, payload sensor interfacing and data management, mission and spacecraft planning software (task scheduling), software testing (validation), providing the participants with a variety of topics to focus on. At the end of their participation at UND, participants will travel to the Jet Propulsion Laboratory where they will be mentored by scientists in the mission and software design groups and conduct a review of their work at UND and a mock mission. They will also tour the facility and learn about the importance of software design systems and processes for past JPL missions. Finally, as an aerospace system, software development will abide by DO-178B/C (Software Considerations in Airborne Systems and Equipment Certification).

该站点由国防部与NSF REU计划合作支持。任务和安全关键系统的软件开发对于美国经济，国家安全和增长至关重要。当系统必须维持人类的生命或通过不良手术伤害人类的能力时，使用适当的设计，开发和测试技术尤其重要。这种REU经验使学生意识到并开始将他们习惯于设计，编程，调试和测试可靠性。即使学生最终没有在专业工作或研究任务关键系统方面工作，这些相同的技术也可以帮助防止软件错误，这可能会导致不良操作或使软件容易受到攻击和妥协。此REU网站向学生介绍了任务关键系统的设计标准。他们正在获得在真正的关键任务网络物理系统上工作的实践经验，并获得了对设计过程重要性的欣赏。参与的学生将参观附近的斯坦利·米克尔森（Stanley R.参与者将参与北达科他大学（UND）开发的开源/开放型Cubesat类卫星（开放型轨道）。 Open Orbiter（Open）是一项学生领导的工作，它正在建立开发，启动和管理Cubesat太空任务所需的完整系统。为了测试所需的各种系统，并为参与者提供实行真正任务的动手经验，PIS每年在太阳能气球上进行一次开放式轨道原型的发射。这包括原型的准备和测试，发射，恢复操作和任务汇报。参与者在所有这些方面扮演关键角色。由于开放式轨道使用Raspberry Pi和四个Gumstix计算机进行车载处理，因此需要多线程编程/并行编程来管理卫星。实际上，开放式轨道系统需要在计算机科学，控制软件（操作系统），地面站软件和图形，有效载荷传感器接口和数据管理，任务和航天器计划软件（任务调度），软件测试（验证）的所有领域开发。参与者将在参加UND参与的结束时前往Jet推进实验室，在该实验室中，他们将在任务和软件设计小组中的科学家指导他们，并对UND的工作和模拟任务进行审查。他们还将参观该设施，并了解软件设计系统和流程对过去JPL任务的重要性。 最后，作为航空航天系统，软件开发将遵守DO-178B/C（机载系统和设备认证中的软件注意事项）。
