Initiative for concerted international cooperation on collection of GNSS Positioning Environment Data using Low-cost Sensors Networks

Satellite navigation is a component of the national and international infrastructure, and has become a public good, in appreciation to the efforts and accomplishments of GNSS operators. Numerous technology and socio- economic applications and services are in operation and under development, all of them relying to sustained and resilient GNSS positioning, navigation and timing (PNT) service quality. The recognition of potential risks due to temporal deterioration of GNSS PNT service quality has become an essential scientific and engineering task. Reliance against natural (space weather, ionospheric, tropospheric, multipath) and artificial (jamming, spoofing, meaconing, systemic failures) sources of vulnerability is today a hot scientific and engineering subject under concern of electrical engineers, mathematicians, statisticians, computer scientists, geodesists, transport and traffic engineers, but also the growing number of the GNSS application operators and users. Space weather, geomagnetic and ionospheric effects are the prime natural sources of GNSS positioning performance degradation. Understanding of the natural processes that generates GNSS signal delays and waveform alterations, the sources of GNSS positioning errors, requires real-time data sets that describe numerous scenarios of GNSS utilisation. What is even more important, such observations of GNSS positioning environment (space weather, geomagnetic and ionospheric conditions) should be taken everywhere in to allow for GNSS positioning environment description on different scales, and for development of accurate and reliable forecasts of GNSS positioning performance deterioration that can be used for mitigation of its sources and for issuing the appropriate alerts to GNSS- based applications and operators. Here the initiative for concerted international co- operation on collection of GNSS positioning environment dana using the networks of low-cost ionospheric space weather activity is introduced. A structural view (ontology) of relevant space weather, geomagnetic and ionospheric activity will be given, based on scientific results related to the subject achieved by GNSS specialists in Croatia and elsewhere. Experience with low-cost sensors of ionospheric activity will be presented. The methodology for utilisation of the in collection of ionospheric activity data through processing raw GNSS measurements obtained from the Google Location Application Programming Interface will be introduced. Finally, a common practice in the international co-operation on the GNSS positioning environment dana collection will be presented in facilitation of the proposed initiative and for recommendation for international collaboration on successful understanding, modelling and forecasting of space weather-caused GNSS positioning performance degradation.
