Why Buying Bluetooth GPS Receivers Can Save You Money
February 8th, 2010 by Phil ZertiskyWith so much focus on events in the news about people going missing on hikes or even during every day chores such as taking your clothes to the dry cleaners, safety has become a major focus today. Someone came up with a way for you to keep track of where you are going and where you currently are. Bluetooth GPS receivers have been gaining in popularity and many people currently own one or two for their vehicles, or personal hand held devices.
A few things you should know about the GPS or global positioning system, the receiver calculates its location by timing the signal as accurately as possible to the satellites orbiting the Earth. The satellite transmits messages that include the time the message was sent, precise orbital information and the information from all GPS satellites. The receiver gets this information and uses it to triangulate, using three points to locate your precise location, translates it into usable information for your location.
The ephemeris data, also known as the triangulation formula, is transferred every thirty seconds, which means that the information could be up to two hours old already. However, due to the speed of light, this information isn't always completely accurate because a slight clock error can become a large error, so receivers use four or more satellites to retrieve the location and time to ensure all is accurate.
Time is something that not all the GPS receivers offer, for some it is a hidden feature only used by the GPS for determining your location. It has an uncanny precision in its equation to determine your location making it one of the most widely used tools for everyday uses.
Having been created specifically with the military in mind, this tool helped soldiers plan troop movements, supply routes, find objectives in new territories or at night when visibility is limited, reconnaissance missions, and even mapping projects. Even the aircraft was assisted by this handy tool for search and rescue missions, missile guidance and air to ground targeting.
GPS started being produced for non military chores because there was a demand for it. People began purchasing it for things like oceanic travel, surveying, or traveling in unfamiliar areas and even assisting emergency vehicles find you.
Many cellular phones have GPS receivers in them, but some are very limited on what they can do. The cellular companies have varying degrees of accessibility and coverage for these phones. Some may be able to simply just determine your location for emergency medical services, others can access maps and plan out routes to get you to your predetermined location.
There are many things that Bluetooth can offer, so a bargain can always be found. Especially when other companies are able to make things that are compatible with the Bluetooth technology. Getting the right thing can be easy once you learn what GPS is and what you should be looking for in a product. Many of them come with the ability to download easy to use user manuals. Battery replacement is easy to as many of them come with cell phone batteries that can be found in almost any store. Convenience at your fingertips.
