E Mail

The International Earth Rotation and Reference Systems Service (IERS) Rapid Service/Prediction Center (RS/PC) produces daily and weekly EOP combination and prediction solutions. The daily solutions are produced after 1700 UTC while the weekly EOP solutions are produced Thursday after 1700 UTC. These solutions include data from Atmospheric Angular Momentum (AAM) analysis and forecasts, Global Positioning System (GPS) solutions, Satellite Laser Ranging (SLR) solutions, and Very Long Baseline Interferometry (VLBI) solutions. The solutions are sent to roughly 700 people by e-mail per week and are picked up in roughly 40000 ftp downloads per month.

Flow Power

Analytical assessment of the water energy resources in Ofu stream segments at Ofokopi, as one of the hydrologic regions of Kogi state, Nigeria was carried out. The principal focus was on the determination of the stream segments parameters of head, flow, power potentials and Environmental Impact Assessment (EIA). Two appropriate sites in close cascade were identified namely, Ofu I and Ofu II. Garmin GPSMAP 76S global positioning system was used to determine the gross hydraulic heads which gave 11.84 m and 8.60 m respectively. Power potentials of magnitude of 330 kW and 118.8 kW and annual energy generation of 2,890.80 MWhr and 1,040.69 MWhr respectively were estimated. The results of the EIA study yield negligible impact on the locality. The estimated power being in the mini hydroelectric schemes category, the identified sites could be developed to provide electric power for socio-economic transformation of the rural area.
