'''Summary:''' Current GPS module capabilities
</p>

This file contains a brief text description of the currently available services
provided by the GPS IO module. This module uses a Conner Winfield Wi125 GPS receiver to
train a 10MHz VCO frequency reference and generate 1PPS and IRIG-B timing outputs.
The 1PPS is synchronous to the 10MHz reference. The control loop for this circuit is
handled by a JVM on the module's FPGA running $ICELIB/lib/IceGPS.java.

To retrieve the GPSDAT results from a SNAPPER/SERVER=9001/GPS=2 with a GPS module on the 2nd IO module site:

nM> icenet get nic1x "GPSDAT" "RTAB"

To get just the seconds of Year from the GPSDAT result which is itself a table into the local results named mysoy:

nM> icenet get nic1x "GPSDAT.SOY" "RTAB" /label=mysoy

To start a GPS server on an ICE card with a GPS module on the MODULE2 site:

nM> pic/server=9009 GPS pic1auto

or from a batch script:

$NMROOT/os/nmbat PIC/SERVER=9009/GPS=2 GPS PIC1AUTO
