Report Rate
For applications that require it, GPS reports are normally received from the internal GPS receiver at a rate of
once per second. Local Delivery reports are sent at this rate. Remote Delivery reports are limited by the "But
no less than X seconds between reports" setting.
RSSI Average Count (1-30)
This value is used for averaging the satellite signal strength.
Autonomous Automatic Vehicle Location (AAVL) Settings
The Autonomous Automatic Vehicle Location (AAVL) feature adds the ability for GPS-equipped Vanguard Cellular
Broadband Routers to transmit position reports either to a host connected to the local Ethernet port or to a remote
host over the cellular network. AAVL allows the system designer to specify the maximum distance or the time interval
between remote position reports.
Position reports can be transmitted in a number of possible formats. When the format is disabled or the Address or
Port fields are blank, no report is sent.
