Capella Space raises $19 million for radar constellation - Sep 2018
"Capella Space, a startup planning a constellation of radar imaging satellites, has raised an additional $19 million to fund continued development of its system. ... has raised approximately $35 million to date...

That funding will support development of what Capella Space ultimately plans to be a 36-satellite constellation providing synthetic aperture radar (SAR) imagery with hourly revisit times. "

"SAR offers the benefit of being able to collect imagery regardless of time of day or amount of cloud cover, unlike optical imagery. However, it’s also had a reputation for being more difficult to work with, an issue Banazadeh said is fading with the rise of automated systems to interpret the imagery and extract the desired information."

Matt Ocko of DCVC: “Commodity trading, urban development, critical infrastructure, shipping and security: businesses across the board realize that milliseconds matter in today’s global economy, and a steady stream of reliable, easily accessible Earth information just does not exist.”

"Commercially, he said major customers will likely come from the infrastructure monitoring, maritime and agricultural markets."

Space Radar Satellites Tracking Earth From Space - Nanalyze June 2018
The ability to shrink space radars down to below 100 kilograms is a real game changer in terms of both construction and launch costs for these types of satellites. ICEYE seems to have taken the lead and is already improving the resolution without adding much bulk (about 20 pounds) to its next-generation SAR satellite. As the constellation grows, it will provide even faster “revisit” rates, meaning updated data on the same geographic location, on the scale of just a few hours. That’s important not just for automating something like shipping traffic but for, say, managing assets during a natural disaster such as a hurricane, where persistent cloud cover would foil optical satellite systems.

European Space Agency teams with ICEYE Finnish start-up - BBC News Mar 2018
"The European Space Agency is to work with Finnish start-up ICEYE on ways to exploit its novel radar satellites. ICEYE-X1 was launched in January - the first of multiple spacecraft that will go up in the coming years. About the size of a suitcase, these are the world's smallest synthetic aperture radar satellites and cost a fraction of traditional platforms."

"ICEYE wants to couple this vision with high temporal resolution, meaning a single spot on the Earth's surface would be surveyed several times a day. Algorithms will scour the data to detect significant changes. High-repeat requires a network of satellites, and ICEYE envisages perhaps 30 platforms in orbit."

A Suitcase-Size Satellite’s Big Image of Frozen Earth Below - The New York Times Jan 2018
"About two weeks ago, a satellite called Iceye-X1 hitched a ride into orbit aboard an Indian rocket. It’s about the size of a suitcase, and has already sent its first picture, constructed out of microwave radar reflections, back to Earth."

"The price for the first satellite was in the “single digits in millions,” Mr. Modrzewski said. He said a more traditional radar satellite would cost a hundred times more."
