GPS: Press this submenu key to turn GPS on or off.
GPS Info: Press this submenu key to display the current GPS information.
Tracked Satellites: Shows the number of tracked satellites (three are
required to retrieve latitude and longitude, four are required to resolve
altitude). Generally, the larger number of satellites tracked, the more
accurate the information.
Latitude and Longitude: Shows location in degrees, minutes, and
seconds.
Altitude: Shows altitude information in meters.
UTC: Universal Coordinated Time.
Fix Available: The cold start search sets are established to ensure
that at least three satellites are acquired within the first couple of
minutes. When three satellites are found, the receiver will compute an
initial fix (typically in less than two minutes). Fix Not Available means
that the initial position has not been established.
Almanac Complete: The system Almanac contains information
about the satellites in the constellation, ionospheric data, and special
system messages. In a cold start, the GPS receiver does not have any
navigation data so the receiver does not have a current almanac. A
complete system almanac is not required to achieve a first position fix.
The availability of the almanac, however, can significantly reduce the
time to first fix.
Antenna Status:
OK: Antenna is connected properly and antenna is working properly
Short/Open: A short or open exists between the antenna and the
connection. If this message is displayed, then remove and replace the
GPS antenna. If the message persists, then try another Anritsu GPS
antenna. If the message persists, then contact your nearest Anritsu
Service Center.
Receiver Status: Current status of the receiver.
GPS Antenna Voltage and Current: Shows voltage and current.
GPS Voltage: Press this submenu key to set the source voltage to be either
3.3 V or 5 V depending on the GPS receiver being used. GPS antenna
voltage is set to 3.3 V by default in order to prevent accidental damage to
lower-voltage GPS antennas.
Reset: The Reset key sets the tracked number of satellites to 0 and erases
any almanac data, along with saved coordinates. The process of searching
for and reacquiring satellites will begin again.
