How GPS Works
GPS (Global Positioning System) is part of GNSS (Global Navigation Satellite System), essential for fleet tracking. It calculates location, speed, and time using satellite signals. At least 4 satellites are needed for accuracy, but Argus uses 8 high-precision satellites to enhance the accuracy of the tracking data.

What is an Odometer?
An odometer is a device that measures the total distance a vehicle has travelled. There are two types: mechanical, which connects to the wheels via a cable, and electronic, which uses sensors to measure wheel rotations and provides a digital readout. Electronic odometers are generally more accurate.
How Do Odometers Pick Up Argus GPS Signals?
Argus GPS units, such as Teltonika and GeoTab, use GNSS signals to calculate distance. The Teltonika unit pings every 500 meters, while the GeoTab GO9 pings more frequently for more precise tracking. Upon initial installation, we enter the current odometer reading, which serves as the baseline for all subsequent calculations. To maintain accuracy and compliance, if a GPS unit goes offline at any point, it's important to update the odometer reading promptly.
