of those 12 NMEA sentences only 4 of them pass a superficial inspection (starts with $GPxxx and ends with *HH) and i wouldn't place any large wagers on them having a valid checksum.
maybe your "power spike" took out the GPS? or maybe something else is reading data from the GPS at the same time? you can't share a GPS by letting multiple processes read from it at the same time. one process gets some of the data, the other process gets the rest. it can look a lot like the data you've shown here. -Jason kg4wsv On Wed, Mar 25, 2020 at 5:23 PM Rodney D.
