To verify the time-stamp accuracy of the DATE-OBS header keyword recored in the fits header for images captured by Mookodi we make use of the procedure suggested by Project Pluto as described [https://www.projectpluto.com/gps_expl.htm here].
== Method ==
The method entails observing a fast moving Global Navigation Satellite Systems (GNSS) satellite that have very accurately known sky-coordinates for a given time. By comparing the observed sky-coordinate of the satellite in your images (after doing astrometric calibration of your images) to the predicted sky-coordinate of the satellite at the respective header time (and knowing the sky-rate of the satellite) it is possible to determine how accurate the time stamping of your images are.
