The ML-232 location module is a specialized telemetry unit dedicated to solutions in many industries, using the monitoring functionality, the status of specific parameters and the current position of a given object.

The design of the module based on the latest GPS/GSM technology ensures precise location and reliable operation in changing conditions of GSM propagation.

The Dead Reckoning function uses a number of additional sensors, making it possible to continue tracking the vehicle’s route in places with limited GPS signal range (e.g. tunnels, underground parking).

The device detects signal interference with external devices (so-called jammers) and attempts to falsify the GPS signal.

The module is made in accordance with the requirements of automotive structures. It is successfully used in the transport of goods, construction and public services. The module is compatible with additional components and the configurator, which allows you to adjust the device in terms of the presentation of specific appearances, such as: the temperaturę level, door opening signaling, loading and unloading signaling, sprinkling and plowing signaling.
