E-MAIL: Tanya Conner, tconner@pop200.gsfc.nasa.gov. NASA's Goddard Space Flight Center (GSFC) intends to contract with NVI, Inc. on a sole source basis to extend support currently provided under Contract NAS5-32331, August through November 2000 plus an additional 2 1-month options beyond the current end date of the contract (December 2000 and January 2001). This extension is required to continue work currently underway while the Government's technical requirements are being competed. Under NAS5-32331, the contractor provides scientific and engineering support to Goddard's Dynamics of the Solid Earth (DOSE) program in the application and improvement of very-long-baseline interferometry (VLBI) techniques. This support includes, but is not limited to: field experiment support; refinement of VLBI technique and instrumentation; theoretical modeling and instrumental calibration of atmospheric propagation; VLBI data analysis; development, maintenance and documentation of VLBI software; application and development of the Global Positioning System (GPS) for global and crustal dynamics; archival and operational documentation of DOSE hardware and software; and VLBI infrastructure support. Support is provided at GSFC, the Haystack Observatory in Massachusetts, Gilmore Creek Geophysical Observatory in Alaska, Kokee Park Geophysical Observatory in Hawaii, and other observatories as required.
