Increasing interest in the IGS, expanding
GPS applications, and most recently the Pilot Project for the
Densification of the IGS, have increased the number of agencies
who contribute to the IGS on a regular basis. These agencies
are jointly responsible for contributing to the international
success of the IGS, and it is only through their dedication, resources,
and participation that the IGS continues to thrive.
