  • Figure 4 illustrates a satellite remote sensing process as applied to agricultural monitoring processes. The sun (A) emits electromagnetic energy (B) to plants (C). A portion of the electromagnetic energy is transmitted through the leaves. The sensor on the satellite detects the reflected energy (D). The data is then transmitted to the ground station (E). The data is analyzed (F) and displayed on field maps (G).

  • These strange-looking planes carry a wealth of sensors in their bulbous noses: colour and black-and-white TV cameras, image intensifiers, radar, infra-red imaging for low-light conditions and lasers for targeting. They can also be armed with laser-guided missiles.
  • Each multi-million dollar Predator or Reaper system comprises four aircraft, a ground control station and a satellite link.
  • Although drones are unmanned, they are not unpiloted - trained crew at base steer the craft, analyse the images which the cameras send back and act on what they see

      The iPlayer service is able to detect you're IP address or ISP through your network and track down your location. As every area has a different IP, it would be easy to locate. There are IP locaters that allow systems to track physical locations around the world.  Unless you use a proxy server, it would be harder to track down your physical location, as it has no direct route back to your computer.
  • f you've got access to a PC back in the United Kingdom you can make a virtual private network tunnel back to that PC and connect to the iPlayer web site thru that PC, this can cause it to look like you are in the United Kingdom.

      A VPN is a private network that uses a public network to connect remote sites or users together. A key feature of a VPN is its ability to work over both private networks as well as public networks like the Internet.

      TOR and Foxyproxy are examples of alternatives for VPN. TOR(The Onion Router), is an online anonymity system keeping user's internet activities from being monitored. Foxyproxy is a a firefox plugin that allows you to add proxies, keeping your ip hidden when you use it.

      Who are the stakeholders and how are they affected by this technology? (WL)

      The stakeholders would be the users of BBC iPlayer. Though they are users of BBC iPlayer, but they only can watch the TV at restricted areas. If they want to have access to BBC abroad they would have to search through the internet for TOR or Foxyproxy to provide them with a VPN. This may cause BBC iPlayer to slow down as there are many free users who are using the website too, therefore users of BBC iPlayer may not be able to watch the TV consistently.
