Meteor M2-3
L-Band HRPT
During a bank holiday weekend I set up the L-Band satellite
tracking antenna I had build earlier in the year to capture some weather imagery
from Meteor M2-3.
It had been a couple of weeks since I last used it and luckily
all the code and mechanical components continue to work well. The capture
bellow show storm ‘Dave’ over Norway after it had passed over Scotland.
