Alternative Architecture for Dual Frequency Multi-Constellation GBAS

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021
This paper describes an alternative architecture candidate proposal for consideration for the future Dual Frequency MultiConstellation (DFMC) Ground Based Augmentation System (GBAS). The GBAS architecture candidate builds off the work done over the last 10 years by the Single European Sky Air Traffic Management Research (SESAR) program.

A new GNSS multi constellation simulator: NAVYS

2010 5th ESA Workshop on Satellite Navigation Technologies and European Workshop on GNSS Signals and Signal Processing (NAVITEC), 2010
With the multiplication of navigation systems (GPS, GALILEO, GLONASS, QZSS, …) and the large variety of signals to be received, GNSS constellation simulators need to be more and more flexible. In the scope of its navigation activities, the CNES has expressed the need for a simulator that, in addition to allow the test of a large variety of receivers ...

On Solving the Multi-Constellation Pseudorange Equations

Navigation, 2010
Future Global Navigation Satellite System (GNSS) receivers may employ a combination of different navigation satellite constellations to provide positioning, navigation, and timing information. As different constellations may not be time-synchronized, the multi-constellation navigation problem involves the determination of position of the receiver and ...

Satellite selection methods for multi-constellation advanced RAIM

Advances in Space Research, 2020
Abstract The increased number of potential threat modes under multi-constellation advanced receiver autonomy integrity monitoring (ARAIM) requires an increase in the number of subsets and a correspondingly high computational load. A new satellite selection method based on integrity support message (ISM) parameters is proposed and compared with GDOP ...

Multi-layered Multi-constellation GNSS Interference Mitigation

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021
Several layers of defense can be implemented in a Global Navigation Satellite System (GNSS) receiver to improve its performance in the presence of interference. These layers include the use of pre-correlation mitigation techniques, post-correlation quality indicators to screen measurements and Fault Detection and Exclusion (FDE) at the position ...

On exact solutions of the multi-constellation GNSS navigation problem

GPS Solutions, 2008
In Global Navigation Satellite System (GNSS) positioning, the receiver measures the pseudorange with respect to each observable navigation satellite and determines the position and clock bias. In addition to the GPS, several other navigation satellite constellations including Glonass, Galileo and Compass can/will also be used to provide positioning ...

Acquisition algorithm for GNSS multi-constellation signals

Scientia Sinica Physica, Mechanica & Astronomica, 2011
Multi-constellation receivers will become popularity since the current satellite navigation systems are transforming from the solo GPS to multi GNSS constellations. The traditional fast acquisition algorithms in time domain and frequency domain for signal of special satellite system have their own shortages.

Android Smartphones for GNSS studies in Multi-Constellation Environment

2020 National Conference on Emerging Trends on Sustainable Technology and Engineering Applications (NCETSTEA), 2020
Modern smartphones are used for various purposes other than core telephony services. They are equipped with GNSS sensors and therefore are used as personal navigation devices. Presence of capable GNSS hardware enables them to be used for collection of GNSS data for geomatic application or basic GNSS research.

Research of Fast Satellite Selection Algorithm for Multi‐constellation

Chinese Journal of Electronics, 2016
We propose a fast satellite selection algorithm for multi-constellation, which is based on both Newton's identities for Geometric dilution of precision (GDOP) fast computation and optimal satellite geometric distribution for less cycle participation.
