I am beginning to look into the program by taking a look at the publications provided here.


Core Flight Software System

Implications of Responsive Space on the Flight Software Architecture

  • Wilmot, Jonathan
  • Short and sweet, it lays out the basics of cFS. Core system, OSAL, Tables. Not an academic paper.

Small Sat Conference (AIAA/USU)

Currently working on a paper for SmallSat2015. The abstracts are refereed, but the papers themselves are not. As such, the papers are a mixed bag in terms of both quality and contribution. The abstract is used to decide whether the work will be presented as a paper or a poster.

CSP: A Multifaceted Hybrid Architecture for Space Computing

  • Rudolph, Dylan and Wilson, Christopher and Stewart, Jacob and Gauvin, Patrick and George, Alan and Lam, Herman and Crum, Gary and Wirthlin, Mike and Wilson, Alex and Stoddard, Aaron
  • The CHREC Space Processor (CSP) is a hybrid device with an ARM processor and Xilinx Zynq FPGA, as well as a collection of other COTS or Rad-Hardened parts. About to be launched on CeREs and STP-H5/ISEM.

Distributed Plug-and-Play Software Architecture

  • Monaco, Christopher and Reid, Mark
  • Converts a command management application from STEREO to work in cFS. Not particularly interesting. Evaluates the performance: gives general numbers for a few limited operations such as ~500 µs for a round trip command on their platform (RAD750 scaled down to 33 MHz, approx. match for STEREO). Plausible overhead sources are mentioned. Big conclusion is that you have to pay attention to scheduling.

Radiation Effects and COTS Parts in SmallSats

  • Sinclair, Doug and Dyer, Jonathan
  • Lays out the idea of "Careful COTS": non-space rated components that are good enough to survive short or low radiation missions. Mostly a pragmatic piece relaying personal experience (Sinclair is from and Dyer is from (recently acquired by Google)). Describes a variety of error types caused by radiation, how to test for resiliency, and actual observed errors in a handful of actual components.

Small Satellites

Fault-Tolerant Control - A Case Study of the Ørsted Satellite

  • Abildsten Bøgh, Søren and Blanke, Mogens
  • Ørsted is a Danish micro-satellite ~ 60 kg. Was not able to incorporate much by the way of redundant hardware. The paper is fairly light, and the software discussed is very simplistic. An enumeration of all possible faults was made, evaluated, and assessed. From this a set of supervisor rules was made with a constraint solver (Beologic). The process was dubbed FMEA (Failure Mode and Effect Analysis).
    The satellite is still in orbit and functional: http://en.wikipedia.org/wiki/%C3%98rsted_%28satellite%29

Early CubeSats: First Round

Canada’s Smallest Satellite: The Canadian Advanced Nanospace Experiment (CanX-1)

  • Wells, James and Stras, Luke and Jeans, Tiger
  • Written shortly before the launch of CanX-1 (the first of seven nano-satellites on six missions) by the University of Toronto Institute for Aerospace Studies, Space Flight Laboratory (UTIAS/SFL). Lays out the basics of the design elements of the satellite, including the onboard computer (ARM7 based) and the payload (two cameras). Describes the Alttitude Control System, thermal and structural analysis, ground communications, and the power requirements. A good overview of how to do a high level design.

Lessons Learned of NSPO’s Picosatellite Mission: YamSat-1A, 1B & 1C

  • Fong, Chen-Joe and Lin, Albert and Shie, Allen and Yeh, Marco and Chiou, Wen-Chen and Tsai, Ming-Hsien and Ho, Pei-Yi and Liu, Chin-Wen and Chang, Ming-Shong and Pan, Hsu-Pan and others
  • A summary view of the development of the YamSat CubeSat by Taiwan's National Space Organization (NSPO). Written before the original launch date, the satellite's launch appears to have been cancelled due to pressure from China (was to be payload on a Russian rocket). Gives a useful overview of the design process, testing procedures, and components used (several of which were designed and manufacture in Taiwan).

The Electronic System Design, Analysis, Integration, and Construction of the Cal Poly State University CP1 CubeSat

  • Schaffner, Jake
  • Describes the design and testing of Cal Poly's CP1 CubeSat prior to its launch. Has the best discussion so far as to the communications system as well as the methodology for testing. Some design decisions were elaborated upon, such as the choice to use COTS components instead of space specific ones (as all the CubeSats in the first round did). In doing so, the paper also seems to make the case for a software only solution to preventing SEUs (the solution here was a watchdog timer for exiting loops and a short mission duration).

Standardization Promotes Flexibility: A Review of CubeSats’ Success

  • Chin, Alexander and Coelho, Roland and Brooks, Lori and Nugent, Ryan and Suari, Jordi Puig
  • A white paper making the case that "standardization equals flexibility" in the case of the P-POD launch system for CubeSats. The P-POD provides launch providers with a trusted, modular platform and removes any concerns about the CubeSat payload while at the same insulating CubeSat developers from the difficulties of finding launch providers and verifying that their payloads will not endanger the primary payload. The P-POD standard is now in its third revision. This paper also provides a useful summary of the CubeSat program and launches, up to 2008.
