In guess, in satellite communication, downlink is the link (selectable connection from one word, picture, or information object to another) from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground station up to a satellite. Some companies sell uplink and downlink services to television stations, corporations, and to other telecommunication carriers. A company can specialize in providing uplinks, downlinks, or both.

In addition to the environmental risk associated with routine operations, offshore and near-shore infrastructure and facilities are vulnerable to malicious acts. These attacks have the potential to cause oil leaks from drilling rigs, FPSOs or platforms, posing risks to offshore personnel as well as potentially significant environmental and commercial impact.

When armed militia groups attacked oil refining and storage facilities in Tripoli, Libya’s capital, fears quickly grew that many of the millions of barrels stored on site could spill. Airbus Defence and Space was commissioned to use its satellite-based Instant Tasking service to provide high-resolution imagery of the facility. Within 90 minutes of the satellite passing over the selected area, a high-resolution image became available to planners working thousands of kilometers away, allowing swift, time-sensitive decisions to be taken.
