[Oliver Montenbruck]

Dear colleagues,

as part of their promotional program, Elsevier publishers have decided 
to offer free access to the article

“The Multi-GNSS Experiment (MGEX) of the International GNSS Service 
(IGS) – Achievements, prospects and challenges"

at

https://www.sciencedirect.com/science/article/pii/S0273117717300418

for a one year courtesy period (until October 12th. 2019).

The article is recommended by the IGS as the primary reference for 
citation in MGEX-related publications. The free access will help to make 
the article accessible to a wider audience and is gratefully acknowledged.

Best regards, Oliver Montenbruck et al.
