The European Geostationary Navigation Overlay Service (EGNOS) is Europe’s first venture into satellite navigation, providing an augmentation signal to the Global Positioning System (GPS) Standard Positioning Service (SPS). It has been a long way for Europe, since the beginning of the EGNOS programme in the late 90’s, culminated with the declaration of availability of the three EGNOS Services:

The International Maritime Organisation (IMO) is developing e-Navigation as the future approach to marine navigation in order to enhance maritime safety. As such, the IMO state that positioning systems for e-Navigation “should be resilient …. robust, reliable and dependable. Requirements for redundancy, particularly in relation to position fixing systems should be considered”

The automation of agriculture has become a significant concern due to the benefits of increased productivity and enhanced operational safety developed in 1997 [1]. In recent years, with the on-going development of mechatronic techniques, traditional manual work has been replaced by automated tools, such as the harvester, mower, and sprayer [2]. However, more specialized farming work still requires human manipulation of farming machinery….

High-performance autonomous pedestrian dead-reckoning (PDR) systems usually include 6 degrees-offreedom (DOF) inertial measurements unit (IMU) to calculate position of the user. These systems don’t rely on GPS signals and preinstalled infrastructure such as RF beacons, Wi-Fi routers, ultrasonic transmitters etc.
