According to European Global Navigation Satellite Systems Agency's 2017 GNSS Market Report 5.8 billion devices are in use in 2017. This number is being expected to increase to 8 billion by 2020. It is for sure that the GNSS has become an essential element of major technological devices and technology developments including but not limited to Internet of Things (GNSS provides localisation and timing information to the interconnected and remotely controlled network infrastructures), Big Data (The proliferation of GNSS devices is boosting the quantity of location and timing data), mobile health (GNSS is used for disability assistance, preventive medicine and emergency) and Smart Cities (GNSS is one of the key technologies used within the infrastructure desing and mobility of smart cities) . Therefore it is obvious that should there be degradation or loss of GNSS signals there might be serious consequences. This article presents the overview of the discussions on the liability for the damages caused by the failure of the GNSS signals and services.
