GSTA

Status: On Going

Activity Code: NAVISP-EL2-078

Start date: 15/09/2020

Duration: 20 Months

GSTA is a follow on of a previous project funded by ESA: the GALIST project (Galileo Smart Traceability, ESA Contract 4000118560/16/NL/LF/hh) which had the objective, exploiting GNSS technology, to certify the position of food production events in order to support the “made in” value added. In order to achieve the stated goal, GNSS positioning solution has to be resilient against spoofing attacks. The GALIST system has already implemented some capabilities for detecting, and counteracting, GNSS spoofing attempts, which we aim to dramatically improve in the GSTA project. The project development is based on the exploitation of a patented anti-spoofing algorithm (ref 102016000110784 dated 3/11/2016,and ref 102019000001135 dated 25/01/2019) based on the integration of data coming from three different sources of information: The GNSS, for continuous, accurate and worldwide available timing and positioning; The ADS-B, as source of a priori unknown messages in terms of content, signal characteristics (e.g. frequency deviation caused by the Doppler shift and the on board LO) and emission time. By design, in fact, ADS-B messages are transmitted by each airplane at random times, in order to avoid message conflicts in accessing the shared ALOHA channel at 1090 MHz (pure ALOHA access); A secure synchronisation mechanism based on a communication network, to provide alternative timing through a secure channel). The unique combination of the three elements above, or part of them when not all contemporary available, provide capabilities to detect the most likely spoofing attacks, i.e. those based on “signal retransmission” (meaconing) and even those based on “signal simulation” (e.g. using commercial HW simulators). In order to achieve its challenging goal the proposing team has been strongly reinforced including two more partners: Fondazione LINKS (formerly known as Istituto Superiore Mario Boella) for its expertise in GNSS and in particular in the field of SW GNSS receivers, SDR based; Istituto Nazionale di Ricerca Metrologica (INRiM) involved for its strong expertise in the field of time services. The project will last 20 months and, in addition to the technology improvement, aims at open new market opportunity no more limited to the food “made in” certification. In particular, we believe that the spoofing detection and mitigation capability can be of interest for many application domains from UAV application to automotive domain including autonomous vehicle, from IOT application to vehicle tracking and fleet management and many more.
