TWP/SONDE/C2 - Wind data missing

A GPS problem associated with Vaisala BBSS ground station software issues caused the 
ground stations to enter into an error state when using GPS wind finding. In some instances, 
the flight was aborted due to the error state and not data was collected.  A workaround 
was developed to allow sondes to be launched without collecting wind data.

TWP/SONDE/C2 - Incorrect latitude

Latitude incorrect:  When the new MRP111 card was installed on 08/08/2011, the DigiCORA 
software (v3.61.1) was also reloaded.  The latitude was incorrectly entered as +0.52.  It 
should have been entered as -0.52.  This mistake was corrected on 12/10/2011 when a 
compromised BBSS computer was replaced and the software reloaded.

Data will be reprocessed.
