Goldstone (DSN)

The GRC Goldstone propagation terminal has been operational since May 1, 2007 and was developed primarily for the determination of the atmospheric phase stability at the Goldstone Deep Space Network (DSN) site for systems planning of the development of an array-based architecture for deep space communications.

Layout of the Golstone Site Test Interferometer (STI)

The layout of the two-element interferometer is shown above.  A 256-m baseline separates two 1.2-m antenna systems monitoring an unmodulated beacon signal broadcast from the geostationary satellite Anik F2.  The elements are aligned on a (nominally) east-west baseline (direction of predominant winds).
