The Fantastic Futuristic Features of the GPS System

man has always speculated about what lies beyond his immediate circle of knowledge. Many a journey has been taken and many a new land has been discovered all because of mans curiosity. The uncertainties faced and risks taken in the name of adventures and travel has claimed many lives. Navigation and maps are vital to these activities.

Luckily for us, we live in an age of new and innovative ways for technology to help us and one of them is the GPS system.

Global Positioning System (GPS) is a worldwide navigation system formed from a constellation of 24 satellites and the associated ground stations. There can be more than 24 operational satellites; new ones are launched periodically to replace older satellites.

Each satellite orbits continually about the same ground track (as the earth turns beneath them) once per day, at an altitude calculated to ensure the satellite repeats the same track over all points approximately each 24 hours (actually 4 minutes earlier each day).

There are six orbital planes, equally spaced (60 degrees apart), and inclined at about fifty-five degrees with respect to the equatorial plan. The GPS system uses man-made stars as reference points to parse accurate positions to within meters.

The GPS system in its entirety is comprised of a network of satellites, signals, support personnel, ground based hardware and software, which make possible the establishment of ones precise location on the Earths surface. The Global Positioning System is funded by and overseen by the U. S. Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military.

The accuracy of location measurements using the global positioning system depends on the GPS receiver. high-end, survey-grade GPS receivers can determine locations precise to within centimeters. but even low-end, handheld consumer receivers, can be accurate to within fifteen meters. GPS receivers have been miniaturized to just a few integrated circuits and so are becoming economical and readily available.

The first commercial global positioning system units were precise for only about 100 meters because the military scrambled the signal--a program called Selective Availability. In the year 2000, the u.s. government removed Selective Availability, improving the accuracy of even basic handheld units to within fifteen meters. Today, with additional information from ground based correction services such as WAAS WAAS (Wide area Augmentation Service) or u.s. Coast Guard differential GPS beacons, accuracy can be improved even further.

Other than PC, our adapter can be easily installed on mac OS-X and Linux. It has fully support of drivers.

Blueunplugged USB adapter 802.11g solution is the innovative design of wireless chipset. The adapter draws its power from the USB port and does not need an external power supply. Transfer data as speeds of up to 54Mbps. Improved error correction keeps the adapter operating at the higher transmission rates for long distances.The Blueunplugged WiFI 54Mbps USB adapter is a compact design and hot swappable giving flexibility and tremendous advantages for desktop and notebook users. When you want to join a WiFI network, install the adapter on the fly no need to reboot.

Wi-Fi was intended to be used for mobile devices and LANs, but is now often used for Internet access. It enables a person with a wireless-enabled computer or personal digital assistant (PDA) to connect to the Internet when in proximity of an access point. It offer WiFi solutions for PC's, laptops, and mobile phones, from leading brands such as Netgear, Kensington, D-link and Belkin. Wi-Fi (or Wi-fi, WiFi, Wifi, wifi), short for "Wireless Fidelity", is a set of product compatibility standards for wireless local area networks (WLAN) based on the IEEE 802.11 specifications. New standards such as 802.16(WiMAX), are currently in the works and offer many enhancements, anywhere from longer range to greater transfer speeds.

High-level hardware-based 64-bit and 128-bit WEP Encryption gives you secure data communication and shields your network from any wireless intruders at no sacrifice to performance. Also, there are advanced security features such as Wi-Fi Protected access (WPA), WPA-PSK and 802.1x support included. Pre-configured to work with Actiontec wireless products or connect to other devices that support the 802.11g or 802.11b standards.

Some information which you may need to provide during driver installation are your wireless client name, your wireless SSID, your computer's unique client name and workgroup name, for your network account - your username and password and finally your IP address, gateway address, and subnet mask if you are not using a DHCP server.Connect your WLAN USB adapter to your PC and install driver. LED turns on when power is applied to the WLAN USB adapter. LED is blinking when PC is sending data through WLAN USB adapter.
