Project site

Radarsat-2 was created on the basis of the PRIMA platform by Alenia Spazio and has a multifunctional synthesized aperture radar that allows you to receive images with a detail of up to 3 meters.

The satellite is designed to monitor the Arctic region and is used in the following areas: ice reconnaissance, marine navigation, hydrology , mapping, geology , exploration of natural resources.

Since February 2015, Canada has provided the Ukrainian Armed Forces of Ukraine with Radarsat-2 images to monitor the implementation of the ceasefire in the Donbass ^[1] . In March 2016, the government of Prime Minister Trudeau decided that Canada spent $ 9.5 million on this expensive program and closed it. .
