GPS Info
• 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 computes 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, contact your
nearest Anritsu Service Center.
• Receiver Status
Current status of the receiver.
• GPS Antenna Voltage and Current
Shows voltage and current.
