Dear Colleagues,

I am pleased to announce the Call for Participation for the IGS Multi-GNSS
Global Experiment (M-GEX). More and more new GNSS systems and signals are
available. GPS and GLONASS broadcast new frequencies and signals, Galileo
launches first satellites in the near future, Japan has its first QZSS
satellite in the sky and China is well along installing its Compass satellite system.
New user equipment is available that can track the new satellites and

The IGS strives to provide highest accuracy products based on all GNSS. To
consistently integrate the new systems and signals, to familiarize with
new data formats, and to develop and extend existing analysis software it
is indispensable to understand in detail the performances of signals and
equipment at the necessary highest level of precision. To collect tracking data
from the new satellites and foster engineering experimentation with the
new signals, the IGS launches a Call for Participation for a Multi-GNSS
Global Experiment, requesting proposals for hosting sites providing new
signals and making tracking data publicly available,  hosting data
centers, and performing engineering analysis. The IGS M-GEX also intends
to interface with existing networks and initiatives such as the JAXA CfP
for hosting sites for a Multi-GNSS Monitoring Network

The M-GEX experiment will run from February 2012 to August 2012. First
results will be presented at the IGS Workshop held in Olsztyn, Poland,
July 23-27, 2012. Eventually the experiment will form a core for a
Multi-GNSS IGS network. The experiment will have oversight by an Experiment
Organizing Committee, to be chaired by Robert Weber, TU Vienna, also
Chair of the IGS GNSS Working Group.

The call for participation is linked to the 'What's New' section of the IGS website

In the near future, IGS webpages will be set up specifically for the M-GEX
experiment, including web forms for the proposal information, which
are also attached to the CfP.

Further, the IGS is a component of the Global Geodetic Observing System (GGOS),
which is a key integrating activity of the International Association of Geodesy (IAG).
There is an additional CfP being circulated by GGOS soliciting proposals for a core
network of multi-technique geodetic sites to define and improve the
Terrestrial Reference Frame and provide essential data for other space
geodesy requirements. Please access this companion CfP at:

I am looking forward for a broad participation and a successful experiment.

With many thanks for your interest and kind regards,

Urs Hugentobler
on behalf of the IGS
