    LOCATION OF ANTENNAS      :
       The GPS satellite signals are received using four microstrip
       antennas mounted on the main mast and behind the wheel house.
       Each antenna is connected to a low noise amplifier (LNA) and the
       four LNAs are connected to the 3DF receiver located in the main
       lab. The 3DF receiver utilizes 24-channels configured as four 6-
       channel sections to make carrier-phase measurements and perform
       real-time differential processing to obtain attitude, position,
       velocity, and time measurements.  The data is output from an RS-
       232 port to the R/V NATHANIEL B. PALMER computer network.

    COMMENTS                    : 
Wierdness with calibrations: watertrack and bottom track suggest more
rotation is needed, but that is not consistent with ashtech (it
worked) and surrounding datasets.  Leave the rotation to match
surrounding cruises (distrust results of calibration calculation)
