Things You Will Learn

  1. Users may not necessarily be aware about the limitations of a GNSS receiver
  2. Users should be critical on the performance of a GNSS receiver, particularly when the technology is becoming highly ubiquitous
  3. The investigation validates the need for GNSS end users testing
  4. This paper is used to inform users, specifically within the Australian context about the ongoing development pertaining independent GNSS testing and certification

Target Audience

GNSS service providers, system integrators and even end users who are critical on the positioning quality of GNSS receivers. The intended audience is not strictly limited to high precision users such as surveyors, but also users who depend on accurate GNSS-derived spatial data.

Presentation Overview
The accessibility of positioning information derived from Global Navigation Satellite System (GNSS) is arguably one of the main drivers that has transformed the way spatial data is currently generated and consumed. As the form factor and power consumption of GNSS enabled devices starts to scale down, the technology will further become pervasive and ubiquitous. This is applicable to both safety and convenience related applications. Depending on what receiver is used, the correctness and reliability of the positioning information may greatly vary and end users may not necessarily be aware of the capabilities and limitations of the receiver being used. In this respect, the blind reliance of end users toward this technology has raised concerns within the GNSS community.

As a part of a broader study on end user needs for GNSS testing, a survey was conducted to investigate the level of awareness amongst end users towards GNSS performance. This paper elaborates on the results of the survey. The findings of this study, together with this needs analysis are used as a basis for principles and recommendations of end user GNSS testing standards and certification guidelines in the context of Australia.

Nuddin commenced his full time PhD candidature in 2012. The research, funded by the Cooperative Research Centre for Spatial Information (CRCSI) aims to investigate both the theoretical and practical aspects of an independent end user testing in the context of Australia. This research has managed to gather a good level of industry participation. Nuddin has a strong interest in multi-discipline collaboration and problem solving. Prior to pursuing research, Nuddin worked as a surveyor cum spatial engineer in ThinkSpatial and has a background in Geomatics Engineering from the University of Melbourne. Apart from research, he also heavily involved in GNSS teaching and training activities within the department.
