Vehicle Gateways (VGs) use Global Positioning System (GPS) data to provide real-time location insights for fleets. Accurate GPS data helps you monitor assets, improve route efficiency, and maintain compliance. To stay proactive, you can set alerts to monitor performance and troubleshoot your Vehicle Gateway.
VGs receive signals from GPS satellite networks operated by third parties. These signals contain timing and location information, which the gateway processes and transmits to the Samsara platform.
Because GPS data depends on third-party satellite networks, signal availability and accuracy are not controlled by Samsara.
In most conditions, GPS data from a VG is accurate within a few meters. This standard is consistent with other commercial GPS receivers and is sufficient for fleet management, routing, and compliance needs.
GPS data accuracy is influenced by conditions that limit a VG’s ability to receive satellite signals. When these conditions occur, GPS data may temporarily be delayed or less precise.
The following factors can reduce accuracy:
-
Weather conditions: Heavy cloud cover, rain, or storms can weaken or scatter satellite signals.
-
Geography: Natural obstructions such as mountains, dense forests, or valleys can interfere with reception.
-
Man-made structures: Tall buildings, tunnels, and enclosed parking structures can block or reflect signals.
-
Device placement: Installation that prevents a clear line of sight to the sky can limit accuracy.
To reduce GPS interruptions, confirm the following conditions are met:
-
Installation is unobstructed: Mount the VG so it has a direct line of sight to the sky.
-
Placement avoids shielding: Do not place the device deep inside the vehicle or under heavy metal components.
-
Power and connectivity are stable: Maintain proper wiring and network coverage to ensure data transmission.
