Multi-GNSS environment

Proceedings of the Second Symposium on Information and Communication Technology - SoICT '11, 2011
In the last decade, the world of Satellite Navigation has experienced an important change: while in late 90s the USA and Russia played a dominant role as only providers of global navigation satellite systems, the new century saw the arrival of new actors with projects for additional global and regional systems.

Multi-GNSS Single Frequency Precise Point Positioning

2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea), 2018
Single Frequency-Precise Point Positioning (SF-PPP) processing strategy is a hot topic in GNSS context, owing to the advantages of a stand-alone, accurate and cost efficiency positioning. However, the existing SF-PPP methods can be hardly implemented for high-precision applications due to the large error sources that affect accuracy and converge time ...

A programmable multi-GNSS baseband receiver

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
This paper assesses the drawbacks in reconfigura-bility and resource consumption of the conventional baseband signal processing circuitry for modern Global Navigation Satellite Systems (GNSSs) signals. The involvement of new GNSSs leads to the requirement of designing a programmable multi-GNSS baseband receiver that can be reconfigured across GNSS ...

Multi-GNSS: Facts and Issues

2017
The world of satellite navigation is experiencing an era of expansion, as the GNSS community is growing. Besides the two already operational systems, the United States of America’s GPS and Russia’s GLONASS, two additional constellations are currently under development and near to be completed: the Chinese BeiDou and the European Galileo.

Advances in multi-GNSS time transfer

2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC), 2013
This paper proposes a method to combine GPS and GLONASS measurements for time transfer in All-in-View, using calibration data for both GPS and GLONASS. GLONASS has to date a complete constellation, but its use for time transfer is made difficult by the existence of biases for each satellite-receiver pair.

GDOP minimum in multi-GNSS positioning

Advances in Space Research, 2017
Abstract In positioning, navigation and timing (PNT) applications with the Global Navigation Satellite System (GNSS), the geometric dilution of precision (GDOP) offers an important index for selecting satellites from all tracked satellites for positioning calculation.

Evaluating PDOP in Multi-GNSS Environment

IETE Journal of Research, 2019
Hybrid operation with two or more Global Navigation Satellite Systems (GNSS) together with (Multi-GNSS) is now popular in the enhanced Signal-in-Space (SiS) scenario that is expected to provide sev...

Broadcast versus precise ephemerides: a multi-GNSS perspective

GPS Solutions, 2014
A consistent analysis of signal-in-space ranging errors (SISREs) is presented for all current satellite navigation systems, considering both global average values and worst-user-location statistics. The analysis is based on 1 year of broadcast ephemeris messages of the Global Positioning System (GPS), GLONASS, Galileo, BeiDou and QZSS collected with a ...

Satellite Selection in Multi-GNSS Positioning

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2016
Satellites selection can be performed based on constellation geometry, ranging-signal quality, or both. For applications where multipath and blockage are not major problems, Signal-in-Space (SIS) user range error varies less significantly, which is the case for many applications most of the time.

Multi GNSS Advanced RAIM: An availability analysis

2014 IEEE Metrology for Aerospace (MetroAeroSpace), 2014
This paper presents multi GNSS Advanced Receiver Autonomous Integrity Monitoring (ARAIM) availability for vertical guidance of aircraft down to LPV-200. Our analysis is based on two data sets: real and simulated data. For analysis based on simulated data, we use MATLAB Algorithm Availability Simulation Tool (MAAST) for availability analysis.
