Very impressive!
This official UK government press release describes these nano satellites as either microwave or shoe box sized, neither one seems nano to me! :-)
"Two of the Spire nanosatellites have an onboard supercomputer and intelligent machine-learning algorithms that can provide hyper-accurate predictions of the locations of boats, track their whereabouts and calculate their arrival times at ports, allowing port businesses and authorities to manage busy docks safely.
Two further Spire satellites launched alongside them today, both of which will be used to forge inter-satellite links. These connections allow satellites to act as relays, sending data to one another and down to ground stations, which cuts the time between data collection and its delivery. ...
The market for these smaller satellites, which are designed to orbit close to Earth’s atmosphere, is growing rapidly. According to a report by the Satellite Industry Association and Bryce Space and Technology, a total of 292 of the spacecraft were launched into space in 2017, compared with 55 in 2016. ..."
