1. An imaging system configured to be deployed on a satellite in geostationary orbit, comprising:

  • an image sensor configured to be positioned toward Earth when in geostationary orbit and configured to produce data of a first image frame and a second image frame of at least a portion of a surface of the Earth, said image sensor configured to capture the first image frame in not more than 1 second, and capture the second image frame in not more than one second; and

    a transmitter configured to transmit the data for the first image frame to a remote location within two minutes of being captured by the image sensor so that the first image may be viewed at said remote location, and said transmitter being configured to transmit the data for the second image frame to the remote location within two minutes of being captured by the image sensor so that the second image may be viewed at the remote location within two minutes of being captured, wherein said first image frame and said second image frame having respective resolutions that correspond with an image at nadir having at least a 500 m resolution when said satellite is positioned in geostationary orbit.
