In the future, it''s deltadrillpressass conceivable that static geo-location router devices will be incorporated in the deltadrillpressass design of all new buildings and retrofitted into existing structures. It would be particularly useful in skyscrapers to have routers positioned at the corners of every floor, perhaps attached to every exit sign, yielding the ability to automatically track the location of deltadrillpressass all firefighters during a fire.The Orange County tests also identified some issues with GPS accuracy on standard commercial GPS devices, Godfrey says. Civilian GPS can experience drift, limiting accuracy to plus or minus 50 - 60 feet. The accuracy of civilian GPS is limited by the Department of Defense, which controls the satellites and reserves the most accurate readings for military operations. Listings this year total 389 jackup units, an increase of 11 from last year. This net increase is the result of seven newbuilds announced for: Atwood Oceanics (1), ENSCO (1), Maersk (1), Pride (2) and Santa Fe (2). Three units were added to Former Soviet Union listings and two to National Iranian Drilling. One rig was deleted from National Drilling Co. of Abu Dhabi''s fleet. The listing excludes deltadrillpressass shallow-water units working in inland waters, and those in non-drilling/workover modes, deltadrillpressass e.g., tender assist, production and accommodation.
