2.00 SCOPE
2.0 The mission of the USNO is to determine time, both atomic and astronomical, to determine and predict the positions of celestial objects and Earth Orientation and to provide this data to the DoW. VLBI observations are used by USNO to determine and predict the variable orientation of the Earth in three-dimensional space as well as to maintain the positions of the extragalactic radio sources which form the basis for the quasi-inertial celestial reference frame, within which the Earth Orientation Parameters are determined.
The objectives of this procurement are, 1) implement a state-of-the-art software based VLBI capability to take advantage of advances in the electronic transmission of observational VLBI data over the Internet to enable near real-time operations; 2) develop a software based VLBI correlator capability to take advantage of advances in high-performance computing needed to process higher volumes of VLBI data from VGOS and next generation VLBA systems; and 3) procure and deliver components for this correlator consistent with new and ...
