We present Galileo Open Service Navigation Message Authentication (OSNMA) observed operational information and key performance indicators (KPIs) from the analysis of a ten-day-long dataset collected in static open-sky conditions southern Finland using our in-house-developed OSNMA implementation. In particular, we timeline with authentication-related events, such as authentication status type, dropped navigation pages, failed cyclic redundancy checks. also report other KPIs, number...
The European Global Navigation Satellite System (GNSS) Galileo is launching the Open Service Message Authentication (OSNMA) to enable navigation message authentication for all users, and therefore increasing resiliency against spoofing. Finnish Geospatial Research Institute (FGI) has developed an open source implementation of Galileo's OSNMA, henceforth known as FGI-OSNMA. FGI-OSNMA a Python library functioning OSNMA computation engine with special emphasis put into its modularity, usability...
We present Galileo Open Service Navigation Message Authentication (OSNMA) observed operational information and key performance indicators (KPIs) from the analysis of a four day long dataset collected in static open sky condition southern Finland using our in-house developed OSNMA implementation. In particular, we timeline with authentication related events such as status type, dropped navigation pages failed cyclic redundancy checks. also report KPIs number simultaneously authenticated...
Ultra Wideband (UWB) signals are a promising choice for indoor positioning applications, since they able to penetrate walls certain extent. Nevertheless, signal reflections and Non-Line-of-Sight (NLOS) propagation cause bias in the measured range. This ranging error can be corrected with Machine Learning (ML) methods such as Convolutional Neural Networks (CNNs). However, these ML models often generalize poorly between different environments. In this work we present an instance-based Transfer...
Satellite navigation has become a widely used resource in many fields. However, satellite signals are vulnerable to different interference sources, both intentional and unintentional. In safety critical situations such as rescue tactical operations robust alternative for Global Navigation Systems (GNSS) is needed. this work we use magnetometers Ultra Wideband ranging together with inertial sensors cooperative manner heading estimation infrastructure independent pedestrian navigation. We...
Situational awareness is critical for safe navigation and autonomous ship operations.To improve safety automate navigation, multi-sensor systems could involve sound-based direction-finding of foghorns. In this paper, we study the performance a three-microphone array in bearing estimation when distant foghorn audible. We presentresults from simulated tests, laboratory tests with synthetic sounds, fieldtests done on cruise vessel Gulf Finland. The results suggest that vesselbearing possible...
