This was my GSoC 2018 Project for the aerospaceresearch.net organization. The project consisted of demodulation and decoding of NOAA APT data in order to extract the weather image sent by the satellite. Another goal was also to accurately detect the sync signal sent by the satellites. This same sync signal can be recorded at different base stations around the world and by comparing the time difference of arrival, we can predict the location of the satellite. The accurate sync detection was successfully implemented for NOAA, METEOR M2, Cubesats. More info can be found here.
