This may out of scope for most users of the RTL-SDR but if you have a local GPSDO time / frequency source, you might consider a coupled injection of a local modulated signal that can be used to time stamp the output bit steam to the required precision, and then sample time derived from the marker detection, assuming the sample clock is stable enough until the next injected (out of band) local. The injected calibration signal could be as simple as a A1 carrier transition, on up to a time synced spread spectrum underneath the noise gloor.

The challenge is that most inexpensive SDR modules do not provide the time stamping of the ADC. Theyâre more a RF to stream of samples device.
