How Accurate is GPS?
The answer to this question keeps changing along with advancing technology as well as United States law. The first consumer GPS receivers on the market were far less accurate than the receivers available today even though the satellites are the same. Also, before the year 2000, the military intentionally introduced inaccuracies into the civilian GPS signal for "security" reasons. They called this intentional signal error "Selective Availability". In May of 2000, President Clinton made a decision to turn off SA and allow civilians access to increasingly accurate GPS signals. The military still has the ability to turn off or introduce errors into GPS signals at any time and with no notice but this ability is generally only used for specific reasons of national security. The best consumer GPS technology available as of 2007 achieves an accuracy level of 15 to 30 feet under normal conditions. Garmin, currently the most popular manufacturer of GPS receivers, claims their GPS units are accurate to within 50 feet 95% of the time. Even within the Garmin GPS receiver line, accuracy specs differ because of the different chips used in the design of different receivers. GPS Receiver Design Affects GPS Accuracy If you are looking for the most accurate consumer GPS unit, it's important to pay attention to the unit's chip type. The latest technology in GPS receiver chips is the SiRFStar III from SiRF. With this chip in your receiver and WAAS enabled you can expect to reach the best GPS accuracy levels available under current conditions. Environmental Factors Affect GPS Accuracy Many different environmental factors can also affect the accuracy of your GPS receiver. Heavy tree cover, tall buildings, deep canyons, and any location in which your view of the sky is limited can affect how accurate your GPS is. Atmospheric conditions can also degrade the accuracy of your GPS unit. As you can see, there is no easy answer to the question "how accurate is GPS?". However, you now know the main factors that can affect GPS accuracy. - 2007, Mark Hamilton Read more about handheld gps systems at HandheldGPSInformation.com
