    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.
