This day's mini-beacon data are not associated with times. We were still developing the LabVIEW program that read and stored the GPS data. 

The next twp days (January 28 and 29) was just a time stamp. These data had an error with the parsing of the GPS data that resulted in many extra time stamps. It is all correct, but not very helpful. 

As of January 30 the full GPS string was being parsed and the data rate was nearly uniform once per second. 

Also, as of the 30th the GPS altitude data are both averaged over 4 seconds (the first altitude data column in feet) and the raw GPS string showing altitude in meters each second.
