TDoA measurements using GPS time-stamped IQ samples from KiwiSDRs (2)

20171203T1836 2117 khz STANAG4285

For this signal the cross-correlations look like this:

TDoA cross-correlations 2117 kHz

There are multiple propagation paths with different delays

Using the time interval indicated by the red lines the following plots are obtained:

TDoA 2117 kHz

It would be good to have a method for finding the best interval instead of doing this manually.

Thanks to all KiwiSDR owners who have made an effort to provide GPS signals to their KiwiSDRs.
