GDOP minimum in multi-GNSS positioning
Advances in Space Research, 2017Abstract 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.

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.

Experimental Investigation of Multi-GNSS in Static Mode [PDF]
2018 IEEE 5th International Conference on Methods and Systems of Navigation and Motion Control (MSNMC), 2018 Due to the numerous beneficial features quadrotors possess, such as high maneuverability, low flying speed, an ability to perform vertical take-off and landing, slow precise movements and hovering, they attract attention of researchers and designers worldwide. Development of reliable autopilot is one of the core challenges they face.

Satellite Selection in Multi-GNSS Positioning
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2016Satellites 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.

An analysis of intersystem biases for multi-GNSS positioning
GPS Solutions, 2014The capability of commercial receivers to track multiple GNSSs poses the problem of mutual alignments of reference frames and time scales. System biases should possibly be computed in advance and made known to the user, so that the only unknowns for code point positioning are the receiver coordinates and the receiver clock offset relative to a unique ...

Cross-calibrations of multi-GNSS Receiver Chains [PDF]
2019 Joint Conference of the IEEE International Frequency Control Symposium and European Frequency and Time Forum (EFTF/IFC), 2019 GNSS receiver chain calibration is a pre-requisite for accurate GNSS time transfer and GNSS time dissemination, which becomes particularly relevant in a competitive multi-GNSS environment. Measurement of GNSS chains based on an absolute calibration approach have been proposed but are not yet operational due to the limited number of results and the ...

Multi GNSS Advanced RAIM: An availability analysis
2014 IEEE Metrology for Aerospace (MetroAeroSpace), 2014This 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.

A Method of Channel Selection for Multi-GNSS Receiver
2019 International Conference on Electronics, Information, and Communication (ICEIC), 2019In this paper, a method of channel selection for multi-GNSS receiver to reduce effect of interference is proposed. The method is to find the LO frequency that can minimize the effect of interference in situations where the sampling frequency and pass band of filter in the receiver are fixed.
