[FOSS-GPS] High SNR Satellites not being used

[Felipe G. Nievinski]

Maybe PRN06 was set unhealthy?
You didn't mention the tracking period.

Check the NANUs, e.g.:
<http://celestrak.com/GPS/NANU/2014/nanu.2014057.txt>

*CONDITION: GPS SATELLITE SVN67 (PRN06) WAS UNUSABLE ON JDAY 198 (17 JUL
2014) BEGINNING 0950 ZULU UNTIL JDAY 198 (17 JUL 2014) ENDING 1507 ZULU.*
