What's new here is that they are trying to get a constellation up very cheap (20M) and expect to get a 50:1 return on investment.
The sensors themselves aren't that impressive and low resolution when compared to RADARSAT-2, TerraSAR-X and CosmoSkymed.
With all the new data that is and will be freely available to everyone, we could use some SoC help on the open source toolboxes BEAM, NEST and others.
Please send in your ideas on what could be worked on for NEST here
NEST could definitely benefit from more GIS functionality with more integration with GeoTools or other Java GIS libraries.
Definitely not the best there is.
Try the community edition of IntelliJ IDEA and you'll see what really helpful tools can do for you.
Code with pleasure.
For visualizing terrain data the open source NEST ESA SAR Toolbox is great.
It automatically downloads SRTM tiles as needed to orthorectify SAR images.
When the interferometry modules are ready it will also be able to generate new DEMs from SAR images
