Figure 155: GPS Server Reporting Interval Settings
• StationaryTimeInterval(seconds) – Set the interval in seconds between periodic GPS sentence reports when the device is stationary. This
overrides the DefaultTimeInterval as long as the unit is stationary. Use this with the StationaryDistanceThreshold to define “stationary”.
(Disable by setting this value to 0.)
– StationaryDistanceThreshold(meters)
– Set this threshold for use with the
StationaryTimeInterval
. A device is no longer consid-
ered “stationary” when consecutive GPS fixes are above this distance threshold. Low thresholds increase the possibility of incorrectly
detecting movement due to GPS “jitter.” (Range: 20–65535 meters.)
• DistanceInterval(meters) – Set the interval in meters that the device has to travel to trigger GPS sentence reporting. Low values increase
the possibility of incorrectly detecting movement due to GPS “jitter.” (Disable by setting this value to 0.)
GPS Clients
• EnablethisServer – Select to enable.
•
KeepGPS Active
– Keep the GPS receiver active at all times, even if no destination exists for position messages. This will place additional
load on the router similar to sending reports to a remote server, but without consuming the network bandwidth.
• ClientName – Create a name for this client. Only letters, numbers, and underscores are allowed.
• Server – This client must have a remote server to report to. Enter a hostname or IP address.
•
Port
– Port number for the remote server (between 1 and 65535).
• UseUDP – Using UDP instead of TCP reduces the load on the router and may save bandwidth. However UDP does not provide any
guarantee for delivery. The router will typically assume sentences have been received by the remote UDP server and will not buffer those
sentences.
• Numberofstoredsentences – Set the maximum number of sentences that can be stored when the router does not have a connection to
a server.
• SpecifyTimeInterval – This restricts the GPS sentence reporting to a remote server to a specific time interval.
COR models include additional options related to GPS sentence types and reporting intervals. These options match those in the
GPS Servers
section above:
• NMEA
• TAIP
• Reporting Intervals
