Polaris is a Python programmable open IoT platform, designed for remote logging and Cloud applications. It is an excellent GPS/GLONASS vehicle tracker, available with 2G, 3G, LTE, NB-IOT modem. The Polaris application, available in Python Zerynth or Arduino, is open source so that it can be easily changed and customized.

Polaris can function as a GPS/GLONASS vehicle tracker, available with 2G, 3G, LTE, NB-IOT modem, but it’s so much more, too. It is a Python programmable open IoT platform, ready to connect to the Cloud with just a few lines of code. Polaris is also 100% Arduino compatible.

Polaris is designed with features like geofencing, real-time tracking, analog sensors, external commands, audio, and SMS.

Advanced features

The default software includes many advanced features such as real-time tracking, geofencing, analog sensors, CAN bus, battery monitor, external commands, audio, SMS, and many others. It works right out of the box as vehicle tracker; the only requirement is a SIM card.

Polaris also allows you to add a Li-Po battery, and run it without the car battery. For example, it can be added to a bicycle, thanks to that external power source.

Thanks to the sensors inputs it can be connected to various sensors. The sensor data can then be easily sent to the Cloud. This makes Polaris ideal for industrial machinery where it is required to measure things like oil pressure, crane positioning, and so on.

Python programmable

With IoT in mind, we couldn’t think of a better programming language than Python. That is why Polaris is Zerynth-powered and Python programmable.

Thanks to the Zerynth license onboard you can program it in Python right out of the box. Zerynth also allows C/Python hybrid programming.

The full Python application is released open source.

Arduino compatible

As we said Polaris is 100% Arduino compatible. It is natively supported by the Arduino IDE, taking advantage of the vast Arduino code base.

The full Arduino application is released open source on the GitHub channel.

Fleet Management Cloud

If you want to track a whole fleet of vehicles at once, you’ll be glad to know that we will soon be releasing a Fleet Management Cloud platform.

All you need to do is connect your smart cars and vehicles. Afterward, you can easily store and analyze the gathered vehicle data.

The hardware is pre-programmed and able to send tracking data right out of the box; you will only need the SIM card and to register the device on our online tracking software. After the configuration is complete, you will see your device on the map.

Soon we will launch our Fortebit Cloud that will offer an advanced and fully customizable Fleet Management Cloud service for all Polaris and OpenTracker customers.

Most popular vehicle tracker since 2012

Polaris is the evolution of the OpenTracker, the most popular open-source vehicle tracker board in the world, which we developed in 2014 and still manufacturing today. Through the years OpenTracker was sold under different brands and is now available on the Fortebit website.

Visit this page if you want to learn more about the OpenTracker.

Both Polaris and OpenTracker are CE and RoHS certified.

Stand-alone or in a kit

Polaris it is available as a stand-alone product and in a kit.

The kit includes:

  • Polaris
  • a metal case
  • an antenna
  • accessories

It is ready to be used as a vehicle tracker. Because its wide voltage input, it can be used on motorcycles, cars, trucks, heavy machinery, etc.

Polaris offers several low power modes (down to <50uA), perfectly suited for IoT and industry 4.0 devices and applications.
