In this study, we measure the effects of two software approaches to improving data and network performance: 1. Content optimization and compression; and 2. Optimizing network protocols. We achieve content optimization and compression by means of BoostEdge by ActivNetworks and employ the SPDY network protocol by Google to lower the round trip time for HTTP transactions. Since the data and transport layers are separate, we conclude our investigation by studying the combined effect of these two techniques on web performance. Using document mean load time as the measure, we found that with and without packet loss, both BoostEdge and SPDY …

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 …
