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 the number of satellites tracked, the
more accurate the GPS 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 Available: No
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 has no navigation data, so
the receiver does not have a current almanac. A complete system
almanac is not required to achieve a first position fix. However, UTC
time is not correct until the almanac is complete, and the availability of
the almanac can significantly reduce the time to first fix.
Antenna Status:
OK: Active antenna is connected and is working properly.
Short/Open: If an active antenna is in use, a short or open exists
between the antenna and the connection. If this message is displayed,
replace the antenna. If the message persists, try another Anritsu GPS
antenna. If needed, contact your nearest Anritsu Service Center. If a
passive antenna is in use, the message should display: Antenna
OPEN Detected or Passive Antenna Used.
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 at 3.3 V or
5 V, depending on the GPS receiver being used. The default setting is 3.3 V
to prevent accidental damage to lower-voltage GPS antennas.
Reset:
The Reset key sets the number of tracked satellites to 0 and erases
any almanac data and saved coordinates. The process of searching for and
reacquiring satellites will begin again.
Back:
Press this submenu key to return to the
Figure 6-4.
