Testing the Communications and GPS

Clicking on the thumbnails below will allow you to see a larger image.

  This is what our boat setup looked like. At the bow, we have the large communications antenna which is mounted on a tripod. At the stern, you can see the yellow GPS antenna. This antenna is responsible for receiving the GPS signals from satellites.   In this picture, you can see Nandish directing his directional antenna toward the base station in the background. To give a bit of perspective, if you look in the background, you can see the dam starting from the left side of the screen. Scanning to the right, our base station is in the middle of where it first turns a lighter green, but before we hit the tree line further in. Abdul is also in this picture since he is testing is Iridium link at the same time. However, he was so pressed for time, he never raised his head for the shot.
  This is our base station for the experiment. On the left side, you see Abdul standing in front of Nandish's communications antenna. For the first half of the day, Abdul stayed at the base and assisted Nandish with experiments using this antenna. To the right, you can see our GPS base station. The disc GPS antenna is fixed on a tripod. Also attached to the tripod are a transmitter and antenna which are responsible for transmitting GPS corrections to the roving receivers in the field.   This is the Iridium set up that we are using. We are using four phones hooked together to help increase the amount of data that we are able to transport through the connection.  
  Here is the Iridium set up hooked up to one of our computers. This shows how the computer will hook up to the phones.
