It would be nice to add a new tutorial on Ephemeris-based estimation.
I was thinking of estimating clock bias for telescopes since it is something that is frequently done on space surveillance trackers.
For example:
* Use SP3 of several Galileo satellites for ephemeris;
* Define one telescope doing RADEC measurements in GCRF;
* Simulate observations with given clock and RADEC biases;
* (Real observations would be better but, as usual, they are hard to come by;)
* Estimate the telescope clock and RADEC biases using the new feature.
