The Contractor (LDEO) shall support the NASA/JPL Global GPS Network (GGN) Element in Russia, collocated with GSN/IRIS seismic stations, for purposes of NASA, IRIS, and NIMA, by maintaining, expanding, and upgrading the GPS operations in Russia. In particular, the Contractor shall:
1.1 Provide a single point of contact for the management of work performed under this CWO.
1.2 Operate the existing GPS stations in Arti (ARTU, the Urals), Norilsk (NRIL, Arctic Siberia), Yakutsk (YAKT/YAKZ, eastern Siberia), Tixi (TIXI, Arctic Siberia), Magadan (MAG0, northern coast of the Sea of Okhotsk), Bilibino (BILI, Chukotka Peninsula), Petropavlovsk (PETP, Kamchatka Peninsula), and Yuzhno-Sakhalinsk (YSSK, Sakhalin Island in the Sea of Japan).
1.3 Deliver data daily from these sites over the Internet to JPL, IRIS, NIMA, and other IGS participants in near real time.
1.4 Install a new GPS station in Moscow (MOBN, under construction, Russian Platform). Scheduled completion: on or before January 31, 2001.
1.5 Deliver data daily from this site over the Internet to JPL, IRIS, NIMA, and other participants in near real time, as soon as the station is established, tested, and operational.
1.6 Deliver data from stations Yakutsk and Moscow over the Internet to JPL in real time (1-Hz sampling rate, 15-min or shorter latency) using the JPL software. Further redistribution of these data to NIMA will be a responsibility of JPL.
1.7 To install a precision cesium frequency reference (CFR: Agilent Technologies Model 5071A) at the GPS station Yakutsk so that the real-time, 1-Hz data from that station will be more valuable for the involved organizations. This CFR was already transferred by JPL to LDEO, tested at LDEO (Figure 3), and is prepared for the shipment to Russia, contingent on the availability of the export license. As of 12-Dec-00, the US Department of Commerce confirmed that the export license shall be granted to Columbia University soon.
1.8 Investigate the feasibility of a configuration at other RUSEG/NEDA stations to support 1-Hz data sampling rate with the 15-min or shorter latency; collaborate with JPL and with IRIS to implement such a configuration wherever possible. Stations with greatest potential in terms of their geographical location and of the quality of Internet are: Norilsk, Arti, and Bilibino.
1.9 Provide bi-annual summary reports to JPL’s GGN Element, to IRIS, and to NIMA on the activities related to this CWO. Schedule completion: first summary due July 1, 2001, second summary due December 31, 2001.
