Integrity Mechanisms for GPS Satellites within the Galileo Architecture
نویسندگان
چکیده
This paper presents the results of the study of a number of options for the provision of integrity data for GPS satellites within the Galileo architecture, and their corresponding impacts. The project was supported by Alcatel Space and was a contribution to the Galileo definition studies (supported by the European Community under the GALA project), addressing in particular, the definition of strategies and mechanisms for the inclusion of GPS satellites within Galileo to realise a combined Galileo/GPS navigation system.

Performance Analysis of GNSS Global and Regional Integrity Concepts
GPS and Galileo are expected to serve as navigation sources for a variety of applications. The most stringent performance requirements are derived from safety critical applications including aviation APV-II respectively CAT-I precision operations. The Galileo baseline architecture specifies a global integrity concept. This means e.g. that besides the accuracy, availability and continuity the sp...
متن کاملAdvanced RAIM System Architecture with a Long Latency Integrity Support Message
Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is a promising concept enabling aviation safety of life operations, in particular approaches with vertical guidance [1]. The benefits of ARAIM would include a reduced ground infrastructure, a reduced dependency on any one GNSS core constellation, and, in general, a lesser exposure to single points of failure. In ARAIM, as in RAIM, the ai...

As Global Navigation Satellite System continues to upgrade, there will be an increasing number of satellites and signals. This offers users benefits such as increased availability and improved diversity of signal. For safetyof-life users like aviation, higher availability of integrity is the key goal. A technology providing integrity with little or no ground infrastructure overhead is receiver ...
متن کاملFurther Development of Galileo-GPS RAIM for Vertical Guidance
With the much anticipated deployment of Galileo, a new partner will rise on the sky of Global Navigation Satellite Systems (GNSS). Equally anticipated is the launch of the modernized block III GPS satellites, which will provide numerous enhancements to the existing system. It is expected that both Galileo and the modernized GPS will become fully operational within the next 10 years. As a conseq...
متن کاملSingle-Epoch GNSS Array Integrity: An Analytical Study
In this contribution we analyze the integrity of the GNSS array model through the socalled uniformly most powerful invariant (UMPI) test-statistics and their corresponding minimal detectable biases (MDBs). The model considered is characterized by multiple receivers/satellites with known coordinates where the multi-frequency carrier-phase and pseudo-range observables are subject to atmospheric (...
