Jog Buttons and Tracking #6

Open tristan3214 opened 7 years ago

Pretty sure this is already a known issue, but I want to put this here.

Jog buttons work, but because tracking is turned off everything moves slightly west in the time the telescope jogs.

I've had more luck with the jog buttons lately. Given the westerly drift when jogging we surely don't need arcsecond-level jogs (although that's the default). Arcminute jogs have been working well for me, even in the east-west direction. Possibly just needs an way to ensure east-west jogs aren't so small that the net effect is the opposite of what you want. =)

Eliminating arcsecond jog option is probably the best bet. However, if you'd like to actually correct this out, you'd need to calculate the time that tracking was turned off for and apply a correction jog for the tracking rate on top of each jog command. If this is done in post, you get the same issue with the correction jog and get a recursive problem. This would need to happen as a pre-estimate calculation to tack on a correction jog to the original command.

So... probably just discourage small jog commands from the software
