A Split-Beam model for generating realistic ionospheric amplitude and phase scintillation in GNSS RF simulators, including a geometrical-optics interpretation and Nakagami-m amplitude behavior.
Evaluation of regional navigation-system concepts with an agile SDR platform combining configurable GNSS simulation and software-receiver processing.
RTK-B combines genetic-algorithm carrier-ambiguity resolution with BGPS™ code-time ambiguity resolution for rapid precise positioning.
Independent university research using a customized ARAMIS SDR receiver for NavIC L5 and GPS L1 acquisition, tracking, ionospheric correction and positioning. The SAC/ISRO-funded work used ARAMIS Navigation API and raw-data access, and compared its GIVD results with an Accord receiver.
Presentation abstract (in Japanese) introducing the multi-frequency ARAMIS GNSS SDR receiver for academic research, with access to its C++ baseband and navigation processors, configurable RF front ends and ionospheric scintillation monitoring.
The concluding article in the simulator series examines simulator specifications and the selection of a suitable simulation architecture for a particular receiver test.
Multi-GNSS test procedures across receiver research, design, validation, manufacturing, certification and maintenance.
Design and operation of generic GNSS RF simulators, including principal architectures, capabilities, advantages and limitations.
An INS-aided tracking-loop design for maintaining robust GNSS tracking under severe signal dynamics and ionospheric scintillation.
BGPS know-how for producing an immediate position solution while retaining a path to precise positioning.
An assessment of GLONASS restoration, receiver development and the commercial prospects of combined GLONASS/GPS equipment.
The engineering challenge of providing seamless, immediate positioning at any location without making the user a satellite-navigation specialist.
A BGPS-based tracking concept designed around the mass and energy constraints of small migratory birds.
An early technical account of the proposed Japanese regional satellite system and its integrated positioning and communication services.
Pedestrian positioning using GPS, pseudolites and supporting infrastructure within Japan’s early ITS research.
