“…The cost and timeline to develop small satellites are appealing and are becoming increasingly common. This is especially true with developers using open-source software like NASA's core Flight System (cFS) (Wilmot and Kane, 2021). The motivation to gravitate towards small satellites is compelling; however, it introduces cybersecurity challenges for space assets and infrastructure (Tucker, 2019).…”

The connection between space and cyberspace domains is increasingly intertwined. Advancements in space technology, decreasing costs for satellite development, and the use of commercial off-the-shelf products present many cybersecurity challenges to space infrastructure. Additionally, space-based global critical infrastructure makes the space domain a prime target for malicious cyber threats. Software-defined radios introduce a potential attack vector for adversaries planning malicious satellite activity. This paper demonstrates how an adversary would send malicious commands via a software-defined radio to affect the integrity of the sensors on the satellite running NASA's core Flight System software. The experiment demonstrates one possible threat vector using a commercially available USRP N210 software-defined radio. The results show that well-constructed messages can be created to manipulate sensors on a target small satellite system. Identifying cybersecurity vulnerabilities like these in space systems can improve security and prevent disruptions for the global space enterprise.

“…Its main functions are processing commands from the ground station, providing an environment for the execution of the ADCS algorithm, and processing telemetry and mission data. The FSW of HiREV is based on the core flight system (CFS), which is an open-source flight software framework developed by NASA's Goddard Space Flight Center [21,22]. The CFS was developed to achieve the following goals: (a) reduce time to deploy high-quality flight software, (b) reduce project schedule and cost uncertainty, (c) enable collaboration across organizations, (d) simplify sustaining engineering, (e) establish common standards and tools across FSW projects and NASA-wide, (f) establish the use of a single platform for advanced concepts and prototyping, and (g) directly facilitate formalized software reuse [23].…”

High-Resolution Image and Video CubeSat (HiREV): Development of Space Technology Test Platform Using a Low-Cost CubeSat Platform

In this paper, we present high-resolution image and video CubeSat (HiREV), the first constructed 6 U platform to reach the space technology test bed stage, developed by the Korea Aerospace Research Institute (KARI). The CubeSat system is a low-cost platform that has been widely applied to various space missions, from missions involving earth observation to deep space. Despite the emergence of the CubeSat technology worldwide, the CubeSat market in Korea is still in the beginning stages, and a standard testing platform is also in demand. For this reason, KARI is starting to develop a 6 U CubeSat platform, which includes a less than 3 U bus system and greater than 3 U payload space. HiREV has been developed with locally manufactured parts, creating a domestic commercial off-the-shelf infrastructure for CubeSat and 3 m resolution camera payload development. Core flight software has also been applied as an on-board flight software system. Presently, we have developed the main system, while HiREV is under space environmental testing.

“…The XFSW implements the XNAV algorithms in C and runs as a single application hosted by the NICER Instrument Flight Software (IFSW), which is based on the NASA GSFC Core Flight System (CFS) [25]. As an application within the IFSW, it receives commands and sends telemetry via the CFS provided publish-and-subscribe software message bus.…”

The Station Explorer for X-ray Timing and Navigation Technology (SEXTANT) is a technology demonstration enhancement to the Neutron-star Interior Composition Explorer (NICER) mission, which is scheduled to launch in late 2016 and will be hosted as an externally attached payload on the International Space Station (ISS) via the ExPRESS Logistics Carrier (ELC). During NICER's 18-month baseline science mission to understand ultra-dense matter though observations of neutron stars in the soft X-ray band, SEXTANT will, for the first-time, demonstrate real-time, on-board X-ray pulsar navigation, which is a significant milestone in the quest to establish a GPS-like navigation capability that will be available throughout our Solar System and beyond. Along with NICER, SEXTANT has proceeded through Phase B, Mission Definition, and received numerous refinements in concept of operation, algorithms, flight software, ground system, and ground test capability. NICER/SEXTANT's Phase B work culminated in NASA's confirmation of NICER to Phase C, Design and Development, in March 2014. Recently, NICER/SEXTANT successfully passed its Critical Design Review and SEXTANT received continuation approval in September 2014. In this paper, we describe the X-ray pulsar navigation concept and provide a brief history of previous work, and then summarize the SEXTANT technology demonstration objective, hardware and software components, and development to date.
