Hi @giaminhhoang , let me move straight to your questions:

Does it support coherent and non-coherent accumulations to improve sensitivity?

Yes. SnapperGPS implements coherent an non-coherent integration. The implementation described in the paper as well as the backend that is currently online use non-coherent integration.

Can it work with CN0 about 25 - 28 dB?

Honestly, we have not done an analysis of the carrier-to-noise-density ratio (CN0). Might have been interesting as a performance measure, though. However, calculating this value is not straight-forward and also not necessary in our SnapperGPS pipeline. We do not "lock" to certain satellite carrier signals. SnapperGPS does not ha…
