The U.S. government plans soon to upgrade technology satellites global positioning system (GPS) to improve the accuracy and reliability. Total money spent for it to reach 8 billion U.S. dollars.

Currently using the 24 GPS satellites orbiting the Earth at an altitude of about 11,000 miles (about 17 500 km) to support its navigation systems on the entire surface of the Earth. However, to perform location determination requires only 3-4 away from the nearest satellite GPS signal receiving device.

The satellites will be replaced one by one gradually to avoid interference. The project was done by Boeing and Lockheed Martin. There are 30 satlit made with 6 in reserve.

The new satellites have the ability to emit a signal up to three times the old satellite. Device at the satellite are also more sophisticated with more accurate atomic clock with the accuracy up to billionth of a second and faster processing. Determining the location of the error rate can be twice as better than the current capacity by a margin of error of about 6 meters.

GPS was originally developed by the U.S. military 30 years ago for military purposes only. However, in its development, its services opened to the public, though still controlled by the Pentagon. Many countries seek rival the GPS such as the European Union, Russia, and China. However, until now practically the only GPS satellite navigation system the most reliable and comprehensive.

Windows Mobile latest version 6.5.3, Garmin Asus M10 is designed to be used as navigational tools as well as a WiFi hotspot.

Chrome OS, announced by Google in 2009, promises to be an open source Linux-based operating system that runs on x86 and ARM. It is based on the Chrome browser, and will initially focus on low-power netbooks with the support of higher-end systems comes later. Currently, Google provided more detailed information on Chrome OS, easy, browser-based OS for netbooks. With emphasis on speed, OS Chrome promises almost instant load times around 7 seconds for a user ID on their computers.

The first Chrome OS netbooks will be available in late 2010. It will not be available as a download to run and install.
