The New IAG Membership Portal
We are pleased to announce the launch of the new IAG Membership Portal, making IAG membership management easier, faster, and more convenient than ever before.
The entire membership process is now handled through a modern and highly automated online system. Registration, selection of membership type, payment, and membership management are all integrated in one place, fully replacing the former manual membership application and significantly accelerating the processing.
People can register in just a few steps, choose their membership type, complete payment securely, and manage their membership at any time. In their personal account, members can conveniently download their membership certificate, invoices, and payment confirmations whenever needed.
Payments can be completed immediately and without transaction fees using our secure credit card or Google Pay payment options. Bank transfer is also available, but it is not recommended outside the European Union due to longer processing times, possible extra bank fees and currency exchange fees.
The following IAG membership types are available through the portal:
-
FULL Membership:
1 year for € 50,- or 4 years for € 150,- (25% discount compared to four 1-year memberships) -
STUDENT Membership:
1 year for € 0,- (certificate from a University or College required) -
RETIREE Membership:
Lifetime membership for € 0,-
The IAG represents a strong and growing international community. Currently, around 270 people are active IAG members, and 813 individuals in total have benefited from IAG membership over the years.
Membership Benefits: IAG membership offers several important benefits, including reduced registration fees for specific IAG meetings (such as the IAG Scientific Assembly and various IAG Symposia), a reduced individual subscription rate to the Journal of Geodesy, and the opportunity to support IAG activities: Membership fees contribute to funding of workshops in developing countries, of IAG Awards, and of travel grants for young scientists.
Renew Membership: We would also like to remind former members to consider renewing their membership to enjoy these benefits again. In 2026, several major events will offer reduced registration fees for IAG members, such as the REFAG Symposium, the XI Hotine-Marussi Symposium, the TIGER Symposium in Geodesy, the Gravity Geoid and Height Systems Symposium (GGHS2026), and others.
⚠️ For all current and former members: an account has already been created in the new system. You can access it at https://geodesy.science/member/login/ using the email address you originally used for your IAG Membership registration. If you are logging in for the first time, please use the “Reset Password” option to set your password before signing in. If you have questions or encounter any issues, please contact us: https://geodesy.science/contact
We hope your interest in becoming an IAG Member has been sparked and that you will apply and enjoy the convenient functionality of the new IAG Membership Portal.
