From a quick look it's not real clear how you would go about extracting time from the software suite. It's certainly useful for navigation though. 

A secondary gotcha is that the TBolt likely has some internal "issues" that distort the data a bit. Running a TBolt on both ends should wash out the ones that are firmware based.

That may enable a pretty simple GPS common view setup. One way to do it: Somebody picks a set of sats and times that make sense. Since the constellation repeats it's going to be a fairly simple table of this sat / that time. At those times they run their TBolt against something pretty good and log the results
