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.

Reliability Monitoring Algorithm in Multi-constellation Satellite Navigation

2013
Global Navigation Satellite Systems (GNSS), including GPS, BeiDou, GLONASS, Galileo and other systems, are becoming more and more widely used in our today life. As a result, multi-constellation receiver that compatible with more than one system will take the place of single-constellation receiver that only uses GPS or BeiDou system.

Research on Train Integrity Monitoring Using Multi-constellation Measurements

2021
Train integrity monitoring is the key to ensure the safe operation of trains. Traditional train integrity monitoring is based on ground equipment. However, with the development of satellite positioning technology, and in order to meet the needs of the next generation train control system (NGTC), the demand for ground equipment should be minimized.

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.

Fault Exclusion in Multi-Constellation Global Navigation Satellite Systems

Journal of Navigation, 2018
This paper comprehensively investigates the fault exclusion problem in multi-constellation Global Navigation Satellite Systems (GNSS). In future GNSS, the heightened likelihood of fault detection events will cause more interruptions in the continuity of the navigation operation.

Initial Results of a Multi-Constellation ARAIM Airborne Prototype

The International Technical Meeting of the The Institute of Navigation, 2017
Advanced Receiver Autonomous Integrity Monitoring extends RAIM to multiple constellations and dual frequency, with the goal of providing worldwide coverage of vertical guidance for aircraft. Availability simulations have shown that ARAIM based on GPS L1-L5 and Galileo E1-E1a could provide global coverage of vertical guidance.

Multi-Constellation-Inspired Single-Shot Global LiDAR Localization

Proceedings of the AAAI Conference on Artificial Intelligence
Global localization is a challenging task for intelligent robots, as its accuracy directly contributes to the performance of downstream navigation and planning tasks. However, existing literature focus more on the place retrieval and the success rate of localization, with limited attention given to the metrics of position estimation.
