Fast, secure and cost-effective remote updates

Updating BlueTraker terminal is fast, secure, convenient and cost-effective.

FOTA stands for ‘firmware-over-the-air’ and is a well-known concept. It’s the invisible technology behind Internet of Things and in particular smartphone and tablet updates and upgrades that we believe happen automagically. But the usability of FOTA is much wider.

The technology is integrated into every BlueTraker terminal and enables them to be remotely updated or upgraded without interruption of the terminal operation. It could, for example, fix a bug, provide system updates or put in place a new functionality or new features.

Changing requirements and new features

Speed, security, convenience, cost-effectiveness and responsiveness are major advantages of FOTA, but there is more.

Bugs and product behavior can be continuously improved even after the device is in the hands of your consumers. Knowing that products will stay functional as updates are released, updates are frequently deployed and are reliable. By adding new features and infrastructure to products after they are released the process augments scalability.

Over the air firmware upgrade functionality can update not only firmware but reconfigure on-chip hardware resources as well. Namely, the IoT is a growing and rapidly changing market with new product requirements where security threats and privacy breaches are some of the biggest factors driving these changes. The design cycle is usually very short and there is a need for constant innovation and deployment of the latest features.


Critical time-to-market needs

Whenever a BlueTraker equipped vessel is within reach of the GPRS signal all the necessary software maintenance tasks are run over the air. It removes the need for cables, computers or third-party programs and particularly for those costly visits to the vessel.

The implementation of the updates/upgrades is via our Cloud-based Telematic Data Aggregation Server (TDS) and the browser-based SecondScreen application. The TDS, in general, receives a variety of data/reports from vessels through the satellite or mobile network communication channel (bi-directional data exchange).

FOTA, on the other hand, is here to update terminal firmware over the GSM network. However, in case of urgency, Iridium satellite constellation can be used as well – a choice made by the SecondScreen operator.


  • Cost effective – no need to board the vessel
  • Instant execution – the update starts immediately after the command is launched
  • User controlled – SecondScreen operator has complete control of the update process
  • Multilevel protection – the process is secure as the protocol is encrypted to prevent unauthorized activity
  • GSM network – affordable solution with the possibility of Satellite channel usage in case of urgency
  • Modular approach – FOTA updates and upgrades various parts/modules of the terminal as well as the application software
