GlobalSat GPS, Windows 7 not working Invalid lines...

[Gregg Lind]

I purchase this GPS from Amazon as I have had problems with running USB devices that did not use Prolific USB driver and also things not working well in Windows 7.

This GPS works with all other app on my Windows 7 Machine.

I dumped the GPS output and also the Roverlog GPS output log.

Roverlog's GPS module doesn't like the decimals on the time of day (222243.000).

If you replace the two occurrences of

      set utc [ lindex $parsed 1 ]

with

      set utc [ lindex [ split [ lindex $parsed 1 ] "." ] 0 ]

then you should be fine.
