NOAA APT on Whit Monday

Reception from the spacekeet on Whit Monday, the 5th on june 2017. While that day the campus was fully deserted the the hertzian space on the campus is as filled as ever. There are many signals between 136 - 138Mhz, most of them seem to be industrial control systems or pagers of some kind. These cause a lot of interference when trying to pick up the odd satellites that happen to transmit on those same frequencies.

Low pass Very noisy and 'low' afternoon pass. One can distinguish, Spain in the bottom right corner. When the satellites pass 'low' that means they are low on the horizon and not directly overhead. The time the signal can be received and the strength with which it can be received are thus reduced.

High pass This is an example of a 'high' pass. One can clearly distinghuish Europe and Northern Africa. At the top one can see the landmass of Greenland. This is the NOAA 15 satellite.

High pass two Another relatively long but noisy pass at 7 in the evening. NOAA-19

Evening pass Evening pass of one of the NOAA satellites. Mostly the atlantic ocean. By the low sun casting long shadows one can see it is an evening pass.
