Global Navigation Satellite Systems (GNSS) has heavily influenced the modern technology and we have come to rely more and more on GNSS signals for various products and services.
In order to operate GNSS applications in a safe and secure way, strictly required in air navigation services, it is important to understand the growing threats to satellite navigation signals. GNSS signals from space are very weak in signal power, and can easily be disrupted by a growing number of threats. GNSS signal vulnerabilities include threats like radio frequency interference, space weather induced ionospheric interference, multipath, jamming and spoofing. The disruption of GNSS, either performance degradation in terms of accuracy, availability and integrity or a complete shutdown of the system, has a big consequence in critical infrastructure. For example, local interference in an airport could degrade position accuracy or lead to a total loss of the GNSS based services which could put safety of passengers in jeopardy. Besides, information and communications services, which are the integral component of economy underlying the operations of various businesses, can also face a big financial loss from the disruption of GNSS. The proliferation of GNSS jammers and other intentional and unintentional threats have presented a big challenge to prevent the aforementioned businesses from financial and safety impacts.
The risk and impacts from these threats can be managed by evaluating the growing threat of GNSS interference, jamming and spoofing.
Our solutions include a portable GNSS threat monitoring system, equipped with reliable and high grade hardware and software, which allows short term and long term monitoring of local GNSS interference environment; signal recording and monitoring (according to the ICAO recommendation and standards) for situational awareness of any drop in signal quality or signal outage and ground validation of GNSS-based flight procedures.
We support our national and international customers from the public sector and the world of business in air navigations, airport operations, communications and relevant technologies based on GNSS.
New products and services based on GNSS are constantly being developed for private and commercial purposes. The European GNSS Agency (GSA) estimates five billion GNSS devices in use around the world – a number expected to grow to eight billion by 2020. The commercialization of aviation activities is not an exception. GNSS technology has given a possibility to maximize capacity and safety in air navigation services. Ground Based Augmentation System GBAS, Space Based Augmentation Systems SBAS and Required Navigation Performance RNP are considered the future of air navigation because of their cost effectiveness and at least equivalent operational performance in comparison to the conventional navigation aids.
