GNSS Measurement and Quality Control (1.04)

The research will address a fundamental question that arises in multi-GNSS environments that supports ubiquitous positioning: How to best test and assess the claims of GNSS technology and service providers in an independent, scientifically robust manner?

The outputs will include methods, algorithms, software tools, experimental results and scientifically validated conclusions.

An additional output will be a pilot study that showcases the outcomes of this research as well as its potential utility.

This research will contribute to a longer term body of work into GNSS quality control within the CRCSI, and towards the establishment of test track facilities that quantify the performance of a GNSS positioning system under variable operating conditions.

Highlights

A user needs analysis has been conducted with users from different GNSS-dependent sectors interviewed. While surveying and specialist applications are generally concerned with hardware technical capabilities, a majority of non-specialist end users are more concerned with the education and training aspects. More interviews will be conducted to provide a more representative sample of GNSS dependent sectors.

The pilot study for scenario modelling has commenced. Different stochastic are being evaluated for system performance assessment.

Comparison and review of the mathematical and statistical theories to evaluate system performance has commenced, with the major challenge being to provide benchmarking from raw measurements.

Project progress was presented at the annual CRCSI Conference.

The research will address the fundamental GNSS question: How to best test and assess the claims of GNSS technology and service providers in an independent, scientifically robust manner?
