<p style="text-align:justify"><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">Dear IGS Community,
</span></p>
<p style="text-align:justify"><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">This IGS Call for Participation solicits support in establishing an IGS GNSS Monitoring Infrastructure (IGS Monitoring Pilot Project) by reusing the existing
Network, Analysis Capabilities, Software, etc. </span></p>
<p style="text-align:justify"><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">This IGS Monitoring Pilot Project further aims to contribute to the International GNSS Monitoring and Assessment (IGMA) – IGS Joint Trial Project” (JTP),
established jointly with the GNSS providers in the frame of the International Committee on GNSS (ICG).
</span></p>
<p style="text-align:justify"><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">The Objective of the IGMA JTP is the establishment of a trustworthy and comprehensive system for international monitoring and assessment based upon a harmonized
calculation methodology.</span></p>

<p><b><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">Background</span></b></p>
<p style="margin-bottom:13.2pt;text-align:justify"><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">The International Committee on GNSS (ICG) established the International GNSS Monitoring and Assessment (IGMA) Task Force at the ICG-6
meeting in Tokyo in 2011, tasked to facilitate cooperation and information between providers and scientific organizations that engage in open service signal quality monitoring. The International GNSS Service (IGS) is playing a key role in producing precise
GNSS products since its inception in 1994. It is active in coordinating the operation of a global multi-GNSS network and generating multi-GNSS products.</span></p>
<p style="margin-bottom:13.2pt;text-align:justify"><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">The ICG recommended at the ICG-10 meeting in Boulder in 2015 that the IGMA Task Force and the IGS initiate a joint Trial Project to
demonstrate a global GNSS Monitoring and Assessment capability, utilising existing resources and infrastructure and avoiding duplication. Participation from non-IGS analysis groups, networks, and data centres is invited to develop benchmarking between groups
and to generate analysis products, cross-sharing between existing IGS functional streams and IGMA activities. Initially, a limited number of parameters is proposed for monitoring to demonstrate the monitoring service and exercise it operationally. This will
be followed by a broader set of parameters to be monitored as the system approaches permanent operations.</span></p>
<p style="margin-bottom:13.2pt;text-align:justify;line-height:105%"><span lang="EN-GB" style="font-family:"Calibri",sans-serif;color:#1F1F1F">The IGS Monitoring Working Group has been established to install,
<span class="grame">operate,</span> and further develop the GNSS Monitoring and Assessment Trial Project jointly with ICG’s IGMA Task Force, considering the Terms of Reference of the IGMA Task Force for the IGMA-IGS Joint Trial Project, utilising existing resources
and infrastructure, and creating publicly available, useful data products.</span></p>
