Frequently Asked Questions

Navtelecom devices support integration using the FLEX protocol. We provide protocol documentation, integration examples, and developer support.

The list of supported vehicles and decoding files is available here:

For reliable GNSS reception, the tracker should be installed with the label side facing upward. The side with the SYS / GPS / GSM indicators and labels must face upward, as the GNSS antenna is located in the upper part of the device.

Incorrect device orientation may reduce satellite signal quality and affect positioning accuracy.

After installation, open Telemetry Data in NTC Configurator and check GSM signal level, GNSS satellites and coordinates, CAN data (if CAN is connected), and data from connected sensors.

If the parameters are updating, the device is installed and configured correctly. If some parameters are not available, open Protocol Settings in the configuration and check whether the required parameters are enabled for transmission to the server.

If the parameters are enabled but still not updating, check wiring, installation position, and device configuration.

For better Bluetooth communication with BLE sensors, make sure the front side of the device is not blocked by metal surfaces. The Bluetooth antenna is located on the front side of the device, near the indicator area.

For optimal signal strength:

• Avoid placing the front side against metal surfaces.
• Keep some space between the device and large wiring bundles.
• Install the device so the front side faces the area where BLE sensors are located.

Trackers with external antennas are recommended in installations where the device is placed in areas with weak signal reception, such as metal compartments, heavy machinery or vehicles with metal body shielding.

External antennas allow the installer to place the antenna in a position with better signal reception, improving communication reliability and positioning accuracy. Navtelecom devices with external antennas support connection of external GSM and GNSS antennas.

Navtelecom trackers support an input voltage range of 9.5–47 V, which allows installation in most vehicles including passenger cars, trucks and industrial equipment.

In electric vehicles, trackers should be connected to the low-voltage auxiliary system (typically 12 V or 24 V), which powers the vehicle electronics. Telematics devices must not be connected to the high-voltage traction circuit.

Always connect the tracker to the vehicle's low-voltage power line.

GPS is a satellite navigation system developed by the United States. GNSS (Global Navigation Satellite System) is a general term that describes all satellite navigation systems such as GPS, GLONASS, Galileo, BeiDou, QZSS and NavIC.

Modern GNSS receivers can use signals from multiple satellite systems simultaneously. Navtelecom devices use multi-GNSS receivers, allowing them to receive signals from several constellations and improve positioning accuracy and reliability.

Under normal conditions, GNSS positioning accuracy is typically 2–5 meters. Accuracy may vary depending on satellite visibility, urban buildings or tunnels, device installation position and antenna placement.

Correct device installation significantly improves positioning accuracy.
