In this blog post I will briefly talk about what I have done in my three month work period at AerospaceResearch.net. I will link to all the code, documentation, blogs etc. that were the product of this work.

In the last blog we discussed how we were able to get the constallation and thus the bits from the input file. In this blog we will look at how we are accurately obtaining the sync positions within the file.

Many modern communication systems are moving away from traditional analog communication methods to digital communication systems. Using a digital system makes the communication more robust, however will make the system complicated. In this blog we will look at the PSK (Phase shift keying) modulation, specifically QPSK and BPSK.
In my last blog we were at a point where we were able to detect the sync locations in NOAA signal. In this blog, we will look at how the image is extracted and corrected. We will also have a brief look over the AFSK1200 decoder implemented by Andreas Hornig.
In my last blog the process of accurately extracting sync locations within the NOAA APT signal was explored. In this blog, I would like to extend the comparison of the two methods that were implemented. Then look at how the process is influenced by presence of noise, sample drops and doppler effect.

Hello everyone!
A little introduction since this is my first post: I am Vinay, an Electronics and Communication engineering student from IIIT Bangalore, India. I am working for AerospaceResearch.net under the Google Summer of Code (2018) programme. This organization was among very few organizations that caught my eye, owing to their very interesting projects in my fields of interest. I really believe in the core ideas of this organization, which is a great motivation for me. So far, it has been a great experience working on my project under the mentorship of Mr. Andreas Hornig.
This blog post will look at how synchronisation signals are being detected in the NOAA APT transmissions accurately.
