A system, which includes a mobile device and a support server, provides real-time notifications to a user whenever imaging satellites are positioned in the vicinity of the user, such that the imaging satellite is in a position to capture imagery of the user's location or a user-specified location. The user may access and purchase, via the mobile device application, available satellite imagery. In certain embodiments, the user may also be provided with the opportunity to issue, via the mobile device, a satellite tasking request such that a satellite will be tasked to capture imagery of a specific location.
