A Software Defined Radio Communications System For A Small Spacecraft, Michael Hlas, Jeremy Straub, Ronald Marsh

Software defined radios (SDRs) are poised to significantly enhance the future of small spacecraft communications. They allow signal processing to be performed on a computer by software rather than requiring dedicated hardware. The OpenOrbiter SDR (discussed in [1] and refined in [2]) takes data from the flight computer and converts it into an analog signal that is transmitted via the spacecraft antenna. Because the signal processing is done in software, the radio can be easily reconfigured. This process is done in reverse for incoming transmissions, which are received by the SDR and decoded by software. Figures 1 and 2 provide …

A reliable communication system is key to the success of a CubeSat mission, allowing for data to be trans-mitted to the ground station and commands to be up-loaded to the satellite. To satisfy this need, the OpenOrbiter satellite (a 1-U CubeSat [1], being devel-oped with a target parts budget of under $5,000 [2]) is leveraging previously space-tested [3], low-cost trans-ceiver design which is based on the SI 4463 IC unit. This board design will be included in the publically available Open Framework for Educational Nanosatel-lites (OPEN) allowing others to modify, enhance and/or make use of the design in the future.

The OpenOrbiter program aims to develop a low-cost framework to facilitate the development of CubeSat-class spacecraft (small spacecraft with nominal dimensions of 10 cm x 10 cm x 10 cm) for a parts cost of less than $5,000. To validate the framework that has been developed, a prototype unit will also be fabricated and tested in low-Earth orbit. In addition to validating the development of Open Prototype for Educational Nanosats (OPEN) framework, the spacecraft will perform on-orbit science. One aspect of the science mission will be to demonstrate and characterize the efficacy of two types of image processing. To this …

The OpenOrbiter project is a multi-department effort to design and build a small spacecraft which will demonstrate the feasibility of the Open Prototype for Educational NanoSats (OPEN) framework. This framework will reduce cost of small spacecraft creation by providing design plans for free. The focus of the payload software group is to design and implement an onboard task processing and image processing service. Currently the project is in the development phase and most large design decisions have been made. This poster presents the major design decisions that have been made for the payload software and how they will affect the …
