Scintillation Modeling and Its Application in GNSS
2017A method to analysis GNSS effects flexibly under various scintillation conditions is presented with a combination of irregularity strength modeling and signal propagating model. Irregularity strength model describes the spatial and temporal variation of strength of scintillation-producing irregularities. The model could be represented in terms of solar

Reconfigurable adaptive linear array signal processing in GNSS applications
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2013The configuration of an antenna array plays a fundamental role in the ability of array signal processing to mitigate interference. We propose in this paper a novel reconfigurable adaptive linear array scheme to overcome the drawbacks of traditional array

A Novel Multimode Reduced-Surface-Wave Antenna for GNSS Applications
IEEE Antennas and Wireless Propagation Letters, 2013A novel multimode reduced-surface-wave antenna is proposed for Global Navigation Satellite System (GNSS) applications. Based on the shorted-annular-ring reduced-surface-wave (SAR-RSW) element and the inverted-shorted-annular-ring reduced-surface-wave ...

Enhanced BCS Waveforms for GNSS Applications
2018 International Conference on Signal, Image, Vision and their Applications (SIVA), 2018An improved performance and an opportunity for compatible spectrum with existing and planned signals must be provided by any novel proposal of signal modulation design for future generation of global navigation satellite systems (GNSS). The new Minimum Shift Keying - Binary Coded Symbol (MSK-BCS) modulation succeeded in providing such requirements ...

Interference awareness and characterization for GNSS maritime applications
2018 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2018An international maritime measurement campaign was done to detect and record radio frequency interferences in the Satellite Navigation frequency bands. The system, installed on a large container ship, consists of a conformal seven elements antenna array, an ad-hoc data recorder system and a multi-antenna navigation receiver prototype.

Applications for Non-GNSS Positioning Systems
2018The widespread adoption of GPS in mobile devices has meant that there has been an explosion in applications (or commonly called “Apps” on mobile devices such as cellular phones and Tablets) that use location information to provide useful services. Apart from direct navigation and tracking functions for vehicles and to a lesser extent people, location ...
