A satellite looper stores and displays a series of satellite images over the same area,
which, in turn, shows the movement of cloud and weather systems.
APT satellite transmissions provide real-time data and are relatively inexpensive to

Ephemeris data allows satellite receiver systems to predict when and where satellites
will be at any given moment. It also allows receiver systems to earth-locate satellites,
which aids in gridding.
TBUS data can be obtained via AUTODIN message, AWN the fleet multichannel
broadcast, or via the Internet.
Part I of the TBUS message contains equator-crossing reference information.
Part IV of the TBUS message contains high-precision orbital calculation elements,
transmission frequencies, and remarks.
