MAG/NAV/M1 - Missing data

Kearfott SEANAV Fiber Optic Gyro system came to end of life on Nov 3, 2012.  A rental 
IXSEA Hydrins III system was secured to replace it with normal operation Dec 6, 2012.

The SEANAV raw GPS data was captured during much of this missing data period yielding only 
Date, Time, Latitude, Longitude, NorthVelocity (m/s), EastVelocity (m/s) records at 1Hz. 
 The gps-only data are available as nav: magnavgpsM1.a1.

Some SEANAV type full motion data are available during a Dec 4 thru Dec 6 testing period 
by special request to the mentor.

Use magnavgpsM1.a1
