The 1.2-m UK Schmidt Telescope recorded several satellites every night of operation. I must have examined some several thousand satellite trails on Schmidt plates and the only occasions a "wabble" was visible was on the rare occasion when there were drive problems. Visual examination could detect deviations of a couple of arcseconds, and with wabble due to drive error, the stars were always elongated in R.A. Depending on the direction of motion of the satellite, these "wabbling" satellites could appear sinusoidal or have a saw-tooth pattern. Having said that, there were some flashing trails that DID "wabble". They were dead straight at their base magnitude, but showed a systematic drift in the position of the centre of the flash from one side of the trail to the other. This was around the 2 arcsec level. Simple maths suggests this represents a few metres for low satellites, so I assumed this was the Sun's reflection travelling across an elongated surface. There may be some other explanation. I never saw a meteor trail with any indication of deviations around the arcsecond level and I saw many tens of meteor trails. It would surprise me if any instrumental record of a "wabbling" meteor was due to intrinsic motion; camera shake from shutter vibration, wind, or from an inadequately damped rotating shutter seeming the likely causes.
