Saving power and system cost with commercial parts qualified for space applications - Story
June 15, 2020Organizations purchasing satellites are on a perpetual quest to extract ever-increasing value from space assets: We see operators of imaging satellites seeking higher image resolution, faster frame rates, finer channel resolution, and more channels to enable advanced multispectral and hyperspectral imaging.

Reduce smallsat component costs by bridging gap between commercial and QML Class V options - Story
December 03, 2018
Constellations of small satellites (smallsats) promise to bring tangible benefits to national security space (NSS) programs, where there is a critical need to minimize construction and deployment costs. Multiple smallsats, defined as satellites with launch mass of 500 Kg or less, can be built quickly and cheaply and then deployed rapidly and responsively to implement a network of NSS assets that address today's ever-changing threat landscape.

Radiation-tolerant FPGAs solve the satellite signal processing bottleneck - Story
June 12, 2015
Dramatic increases in sensor resolution in remote-sensing space payloads are causing a processing bottleneck, as downlink bandwidth is not keeping pace. Operators require onboard processing so that satellites send processed information, not just raw data. It is a growing challenge for the roughly 100 remote sensing satellites launched each year, each carrying as many as eight payload instruments. Flash-based field-programmable gate array (FPGA) technology is now being applied to the problem, combining high-speed signal processing with special built-in radiation mitigation techniques to keep systems operational in harsh radiation environments.
