The paper says the current generation of CCD detectors aren't fast enough to detect that change in light flux with >1% accuracy, as they integrate the light collected over tens of seconds.
The next generation of CMOS-based detectors might be fast enough.
There are some issues to handle, like the complex light curve of the satellite itself affecting the detection, and the relatively low density of bright-enough stars along the path between telescope and ISS.
The paper suggests using the tens-of-thousands of satellites in upcoming launches to improve the odds.
