Full-text available
Nowadays MEMS sensors, like accelerometers, gyroscopes, and magnetometers, are spreading in a wide range of applications, because of their small size, cheapness and increasing performance. For instance, smartphones are currently equipped with this kind of sensors, which could be used to improve the user experience of the phone itself or the navigat...
Article
Global Navigation Satellite Systems (GNSSs) are theoretically able to provide accurate, three-dimensional, and continuous positioning to an unlimited number of users. An important shortcoming of GNSS is the lack of integrity, defined as the ability of a system to provide timely warnings in case of malfunction; this problem is especially felt in saf...
Article
Precise Point Positioning (PPP) is a technique able to compute high accuracy positioning anywhere using a single GNSS receiver and without the need for corrections from reference stations. A wide range of possible PPP algorithms, using different correction models and processing strategies, exist for both post-processing and real-time applications....

p class="Abstract">In GNSS context, absolute positioning is a widespread operational mode, largely used in many field activities as automotive, aerospace and ships navigation. The functional model of absolute positioning, relating pseudorange measurements to unknowns, is well defined, while its stochastic model, defining the behavior of measurement...

Global Navigation Satellite Systems has a key role in current and future Communication, Navigation and Surveillance infrastructure for aviation application. In air navigation the use of GPS as support to the equipped navigation systems is in use only during less restrictive flight phase (i.e. en-route phase over oceanic areas). In other kind of ope...

Full-text available
Galileo is a global civil navigation satellite system developed in Europe as an alternative to the GPS controlled by the US Department of Defense and GLONASS controlled by Russian Space Forces. It is scheduled to be operative in 2013 and it will have 30 satellites orbiting on three inclined planes with respect to the equatorial plane at an altitude...
Conference Paper
In signal-degraded environments such as urban canyons or mountainous areas many GPS signals are blocked by natural or artificial obstacles or severely degraded; hence GPS-only cannot guarantee an accurate and continuous positioning. The multi constellation approach, integrating different GNSS systems, is a possible way to fill this gap. GLONASS, th...
Conference Paper
Full-text available
In order to guarantee future generations, a fair and consistent level of environmental quality is necessary to ensure sustainable development of coastal resources. Adopting a static mode approach towards sea-level rise conflicts with sustaining a dynamic coastal system that responds to perturbations via sediment movement and long-term evolution. In...
Conference Paper
Satellite navigation is critical in signal-degraded environments such as urban canyons and mountainous area, where many GNSS signals are blocked by natural and artificial obstacles or are strongly degraded. Hence standalone GPS is often unable to guarantee a continuous and accurate positioning. A suitable approach could be the integration of severa...

Full-text available
The GLONASS (Global Navigation Satellite System) is a satellite positioning system able to provide various numbers of air, marine, and any other type of users with all-weather three-dimensional positioning, velocity measuring, and timing anywhere in the world or near-earth space. As known, a GLONASS receiver performs passive measurements of pseudor...
Conference Paper
Full-text available
The GPS Standard Positioning Service (SPS) does not provide suitable performance in all environment conditions or in every possible applications. In severely signal degraded environments, e.g. mountainous or urban areas, where a lot of GPS signals are blocked by buildings or natural obstacles, the positioning is inaccurate because of bad satellite...
Conference Paper
Full-text available
Since 1993, the civil aviation community through RTCA (Radio Technical Commission for Aeronautics) and the ICAO (International Civil Air Navigation Organization) have been working on the definition of GNSS augmentation systems that will provide improved levels of accuracy and integrity. These augmentation systems have been classified into three dis...
Conference Paper
Full-text available
In the Civil Aviation field, the international trend (through ICAO, EUROCONTROL) is to adopt one positioning system that allows to follow more flight phases. This will allow to release themselves by ground installations and optimize the traffic flows following the aRea Navigation (RNAV) concept. In order to realize this goal the European Scientific...
Conference Paper
Full-text available
The GNSS (Global Navigation Satellite Systems) are not sufficient to support Air Navigation in specific applications; so it is necessary to introduce Augmentation Systems. In the last years the European Scientific Community are focusing on Augmentation Systems based on Satellite infrastructure (SBAS - Satellite Based Augmentation System) and on Gro...
Article
In this paper two devices as applied to a marine sextant are presented. A night viewer replaces the usual telescope to allow observation of the horizon in darkness. In addition an automatic reading of altitude is made practicable by a ten-bit encoder mounted on the index arm. In this way the proposed Celestial Navigation Automated Global System may...
Article
Many T, S, O2, marine currents and meteorological data, observed with modern techniques and instruments, have been collected by the Institute of Meteorology and Oceanography in the Bay of Naples from 1977 on. Even, if the variability was large, some flow patterns were recognized as well as changes in the trend of currents: a periodicity of 3 to 7 d...

Riassunto Da anni il GPS è stato sfruttato in modo crescente per fornire la soluzione di posizione in navigazione per varie applicazioni. In fasi critiche della navigazione (operazioni di attracco delle navi, avvicinamenti aeroportuali di velivoli, etc.) sono richieste prestazioni superiori che non possono essere fornite dal solo GPS. Molti studi s...
