Opening the door to new signals


I don't manage to keep my promise of updating regularly this blog (blush). Anyway, I am improving little by little so another pretty stable thing is a board which I use to capture the new civil signals from GPS, Glonass, Galileo, Compass. I might refer to it as "TUNE".

Figure 1: Six single channel TUNE boards.

With a much wider bandwith than PRIMO, these boards can capture through USB a continuous endless stream of E5AltBOC signal with 1 bit quantisation (122.88Mbps). Two can also be connected together to have some sort of a dual-frequency sampler.

At the moment, the GUI to configure everything (tuner, clock distribution, ADC) is a little "complicated":

Some results of acquisitions and tracking of "famous" signals will follow shortly.

Regards everyone and thanks for all the comments had so far,
