Using the precise time and position information, the GPS receiver will be able to determine your exact location anywhere in the world through the GPS coordinates of your ex Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/14.php http://www.WhyGPS.com/GPSTips/14.php GPS works by receiving from the various satellites signals that indicates where the receiver is. The amount of time and the position of the satellite at the time determine where the person is. The satellites determine the amount of time it took the signal to travel from the satellite to the r Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/2.php http://www.WhyGPS.com/GPSTips/2.php Selective Availability is a feature included in GPS. This is made intentionally to degrade signals that GPS receives. With the SA on, the accuracy of the GPS is lowered, while if it is off, the accuracy rate is higher. The SA was included in the GPS for the reason that during war, SA is suppos Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/5.php http://www.WhyGPS.com/GPSTips/5.php Currently the number of GPS satellites in the GPS constellation listed at the records of the US Navy is 29. However, the number of GPS satellites at a given time in the GPS constellation is determined according to the availability of the satellites. Meaning there is no exact number of satellit Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/6.php http://www.WhyGPS.com/GPSTips/6.php There are concerns regarding GPS and radio frequency interference. All signal devices can be interfered by another device whether intentional or accidental. The government is finding ways to detect the causes of interference that may affect the transmission of the GPS. The government also thin Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/7.php http://www.WhyGPS.com/GPSTips/7.php There are many possible reasons why you cannot lock your GPS receiver with any satellite. Like any other radio devices, when signal is weak there will never be a clear connection. However, if you are receiving strong signals but cannot lock with any satellite, the satellite may be offline for Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/9.php http://www.WhyGPS.com/GPSTips/9.php A 12-channel GPS receiver contains 12 channels reserved for satellite communication purposes. On the other hand, a 16-channel GPS receiver also contains 12-channel preset intended for satellite communication. The additional channels provides faster lock-on, enhanced up-to-date information, and Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/13.php http://www.WhyGPS.com/GPSTips/13.php Everything here is © Why GPS, Copyright 2009, All Rights Reserved Worldwide.
