What's Needed? ● ● ● Need ability to track radio sources Need a reasonable bandwidth Need high time resolution (~ 100Hz) ● May also need remote sites to be converted to 1420MHz
Radio Source Tracking ● ● ● ● The mainland EISCAT antennas were never designed to track radio sources, only to slew at a constant speed between fixed positions. Tracking is achieved by slewing the antenna to a new position just ahead of the radio source every few seconds. The radio source then drifts through the beam before the position is updated again. Rate of antenna position update set to 2.56s for convenient filtering of any effect of doing this. ● The ESR does have a tracking mode, so this does not apply to that antenna.
