The satellite has been providing data to the United States Space Surveillance Network since January 2014.
How well can military satellites see?
So the detail visible in a satellite image all depends on the mission of each satellite and the scale of its observations. A few non-military satellites can see objects down to about half the size of a car. Some military satellites can still see even smaller things. But that does not tell us the whole story.

Can satellites be used for surveillance?
Aerial surveillance and migration flows. Within the more than 3,000 active satellites orbiting earth, some are dedicated to monitoring migration flows or used for this purpose. Those are either owned by governments and agencies like Frontex or by private companies that then sell access to the data they collect.
Is Shaw Direct owned by Rogers?

How many military GPS satellites are there?
The space segment of the GPS programme consists of 24 operational satellites in six circular orbits at an altitude of 20,200km (10,900nm), with a 12 hour period, at an inclination of 54.8°. The satellites are positioned so that at any one point in time, six of them will be in view to users anywhere in the world.
