Citizen Science for GNSS Performance Monitoring and Assessment

Citizen Science is a new form of voluntary involvement of lay-individuals in collection of data (observables) with potential of providing new scientific or engineering insight into and understanding of observed processes. With technology becoming more affordable, the lay- individuals around the world increasingly donate money, effort and time in collecting data with potential of later scientific or engineering analysis. Two case scenarios (of the observation processes conducted by amateur meteorologists and ham radio operators) are presented in order to illustrate the potentials, benefits and pitfalls of such activities. Here the Citizen Science approach is proposed as a partial solution for a chronic lack of field data desperately needed for targeted analysis of GNSS performance monitoring and assessment for a number of GNSS-based applications (the mobile ones in particular) that require Quality of Service established by GNSS performance. An honest account of reasonable expectations from such an activity is given, along with the methods and techniques for data cleaning from measurement noise and error, and open-source software-based data processing. Finally, a call for an initiative for a UN ICG-backed international cooperation on establishing standardised procedures for GNSS Citizen Science data collection, storage (with open access), processing and interpretation is presented, with the aim to provide researchers, engineers, business developers, regulators and general public with a framework for impartial GNSS performance assessment based on field data.
