Unpowered Asset Gateways (AGs), such as the AG45, AG46, and AG51, use GPS to record and report the device location during check-in. When the AG is unable to obtain a GPS signal, it uses an approximate location using the nearest cell tower to connect for check-in.
The error range for the cell-based location can vary from a 0.1-1.5 mile radius. Location accuracy can diminish in any of following circumstances:
-
Satellite signal is obstructed. Common obstructions include buildings, bridges, metallic structures (such as within metal trailers), and trees or the AG is indoor or underground.
-
Signal is reflecting on a nearby building or wall.
-
Interference in signal due to radio interference or jamming.
-
Interference from major solar storms.
-
Satellite maintenance or maneuvers causing temporary gaps in coverage.
To view the unpowered AG check-in times and locations, select the AG from the asset list (Overview ( ) > Assets > Unpowered) and locate the Check-in History
.
The check-in history annotates approximate locations ( ) and the location marker on the map indicates Approximate location due to weak GPS signal
. Hover over the location marker on the map to view the accuracy of the location.
