implemented and what are the quirks that have to be emulated properly
for various apps to function?

Very few (if any?) apps try to *set* a guide rate. (the Meade Autostars don t let you change the guide rate remotely) Instead, they do a calibration step,Message 48 of 48 , Jul 18, 2012View SourceVery few (if any?) apps try to *set* a guide rate.
(the Meade Autostars don't let you change the guide rate remotely)
Instead, they do a "calibration" step, whereby they move a little bit around a target star, and use the measured effect (as seen by their camera) to determine the existing guide rate.
The user may have some input into the process by setting "gain" and/or "aggressiveness" and some hysteresis parameters.
Some Meade Autostars do allow handbox-setting of guide rates.
have fun at GSSP
