Ground Station

Ground station

We now have the ground station partly operational. So far, we only got access to polarization, but during summer and autoumn, we will mount equipment to gain access to the other polarization alternatives also.

We have one antenna mast with tracking capabilities with UHF and VHF yagi antennae. In addition, we have a "mobile" turnsitle antenna for weather satellite (NOAA) data reception.

Weather satellite example

This is an image downloaded 11th February 2011, from NOAA19. We can clearly see most of Norway, and aparently, it was a sunny day! The image spans from north of Norway and south to northern parts of Spain and Italy.

The signal from the weather satellites is converted to an audible signal which is loaded into a decoder program that assembles the picture. There are several types of images accessable in the downloaded signal, the picture above displaying channel a. Click here to download the file this image originates from. The data signal can be clearly heard approximately two minutes into the recording.
