I'm looking for some kind of not overly complicated means to synchronize the clock on an HP 48GX or HP 50g with an accurate time source that doesn't involve me pushing a button (reaction time = human error) to do so. I'm confident someone has already done this, but I haven't found any reports on such.
I'm a geomatics student looking to remove at least a portion of this kind of error from celestial observations. Although it would be pretty easy to use the TIME function to quantify my reaction time error, I'm looking into the possibility of removing some of it entirely.
Thanks for any leads. -John
