Those are excellent questions and I thank you for them.
We are currently considering at least four potential solutions.
First of all, there is open data. We are promoting within the government family the wide use of free and open data, which is available more and more.
The second element is commercial data. There are international and Canadian capabilities that we are very interested in.
The third element is a sovereign system—the RADARSAT Constellation Mission, RADARSAT-2 and the upcoming RADARSAT+—which addresses that element.
The fourth element is international collaboration. We have very close relationships with our allies. We have very close relationships with the EU and the European Space Agency. We have an arrangement for contingency planning with the European Space Agency. For example, about a year ago, the European Union lost the Sentinel-1B satellite. They required our support, and we provided support to them with respect to that. Reciprocally we expect that if something happens on our side, they will provide us with support.
We are working very closely with Japan's space agency, JAXA. We have a memorandum of understanding. We have a very active exchange of RADARSAT Constellation data for data from ALOS-2 and the upcoming ALOS-4 that will provide Japanese satellite advanced synthetic aperture radar data over Canada.
We have excellent relationships with our closest partners at NASA. In a few months NASA, in partnership with India, is going to launch a NISAR mission. This will have great coverage at six-metre resolution by L-Band SAR over Canada. We made an agreement that we will provide RADARSAT Constellation data over Greenland. In exchange, we'll get NISAR data in Canada.
We continue discussions with a number of other like-minded nations with which we hope to have relationships as productive as the one I just mentioned.
