Tyvak Nano-Satellite Systems，Inc目前正在开发一种平台独立的纳米运载火箭（NLV）航空电子系统，通过修改和优化现有的CubeSat产品，用于这种新型运载火箭。之前通过NASA的发射服务计划进行的第一阶段SBIR工作为该架构奠定了基础，其中对全球定位系统（GPS），惯性测量单元（IMU）和无线通信协议的关键交易进行了评估。最近授予的第二阶段SBIR将为TRL 7的硬件和软件元素提供资金。Tyvak是NASA发射服务使能探索与技术（NEXT）计划的团队成员，该计划将于2016年演示轨道飞行。该架构的固有模块化为使用CubeSat级电子设备的自动飞行安全系统（AFSS）提供了一条发展道路。该设计允许电子设备重复使用，同时为特定的运载火箭应用提供直接的定制。这种方法提供了航空电子设备质量的显著节省，并通过通用硬件元件和范围资产的减少来降低成本。本文介绍了航空电子系统的体系结构，并讨论了用于定制的航空电子设备，以特定的飞行器的质量和可靠性优化的方法。
Tyvak Nano-Satellite Systems, Inc is currently developing a platform independent Nano-Launch Vehicle (NLV) avionics system by modifying and optimizing existing CubeSat products for use with this new class of launch vehicle. Previous work on a Phase I SBIR through NASA's Launch Services Program helped lay the foundation for the architecture, where key trades in Global Positioning System (GPS), Inertial Measurement Unit (IMU), and wireless communication protocols were evaluated. A recently awarded Phase II SBIR will fund the hardware and software elements to TRL 7. Tyvak is a team member on the NASA Launch Services Enabling eXploration & Technology (NEXT) program to demonstrate an orbital flight in 2016. The inherent modularity of the architecture provides a growth path towards an Automated Flight Safety System (AFSS) using CubeSat class electronics. The design allows electronics re-use, while providing straightforward tailoring for the particular launch vehicle application. This approach provides significant savings in avionics mass, and reduces cost through common hardware elements, and reduction in range assets. This paper covers the avionics architecture, and discusses the approach used for tailoring the avionics to the particular vehicle for mass and reliability optimization.
