Introduction

The ionosphere plays a crucial role in the performance of Global Navigation Satellite System (GNSS). Currently, the 25th solar activity cycle is approaching its peak years. During this period, the occurrence and intensity of ionospheric anomalies such as scintillation, disturbances, and storms are expected to increase significantly. The influence of the ionosphere is uniform across all global navigation satellite systems, and ionospheric anomalies exert a considerable global impact. The monitoring of GNSS performance is a fundamental activity within the International Committee on Global Navigation Satellite Systems (ICG). However, progress towards an interoperable and compatible way for maintaining and improving the performance of GNSS standard and precise positioning during current as well as future solar activity peak period remains limited.

ICG encourages international GNSS and ionospheric space weather communities including ICG service providers as well as members to work together by conducting a workshop aimed at discussing the ionospheric impacts on GNSS and joint actions to be undertaken to mitigate the ionospheric impacts on GNSS during current and future solar activity period through international collaborations.

Objectives

The goal of ICG Multilateral Workshop on ionospheric impacts on GNSS is to establish a foundation for sharing knowledge and strategies to mitigate ionospheric impacts, while promoting interoperable, compatible, and international coordinated efforts for global communities.

The objectives and topics of interest are:

1. Identify and classify of notable ionospheric impacts on GNSS.
2. Analyze strategies and collaborative actions applicable to GNSS service providers and users.
3. Propose recommendations that may be taken up by the GNSS community as well as service providers.
4. Consider new monitoring and alert services for mitigating ionospheric impacts on GNSS to address current and future solar activity period challenges.

Expected Participants

The workshop is for everyone interested in ionospheric impacts on GNSS and international collaboration to meet current and future solar activity period challenges.

The workshop welcomes experts and policymakers from regional, national and local institutions, private organizations, academic institutions, non-governmental organizations, and international organizations from both developed and developing countries.

Especially encouraged to attend are representatives from international GNSS and ionospheric space weather communities including ICG service providers as well as members; experts in GNSS positioning and ionospheric monitoring.
