Are global positioning system external antennas safe
Jul 22, 2017

                                           Are global positioning system antennas safe             


             

The global positioning system began in 1958 with a U. S. military program that was launched in 1964. In 1970s, the United States, navy and air force jointly developed a new generation of satellite positioning system GPS.  The main purpose is for the sea and air three major areas to provide  real-time, all-weather and global navigation service, and for  information gathering, nuclear monitoring and emergency communication  etc. some military purposes, through the experimental study of more than  20 years, at a cost of $30 billion, by 1994, global coverage of 24 GPS  satellites constellation has set up to 98% complete.  In the mechanical field, GPS has another meaning: product geometry,  technical specifications (product geometry, technical specifications,  referred to as GPS). Another meaning is G / S (GB per second). GPS (generalized processor sharing) is generalized to processor sharing, a term used in network service quality control. The external antenna signals are relatively better. The built-in antenna is convenient.

And nothing at all. GPS, GSM, GPS are used for location, GSM  is for communication, and there is a AGPS that can locate base stations  using mobile signals.

In the signal is not good, with external antenna can locate accurately.
