The difference between the beidou antenna and the GPS antenna
Aug 07, 2017

Omni-directional antenna according to two different satellite navigation system, introduced a variety of GPS antenna, GLONASS antenna, the Big Dipper antenna. Share the difference between the two systems:

Compass is a satellite released by China, and now has not provided data to foreign countries, only for domestic satellite navigation equipment business development. The GPS is released by the United States, GPS applications have been covered by the world. China Beidou Navigation System (BeiDou (COMPASSNavigation Satellite System) is China's ongoing self-development, independent operation of the global navigation system,

Difference 1: Antenna frequency

    GPS antenna frequency: L1: 1575.42MHz

    Compass antenna frequency: B1: 1561.098MHz

                 L1: 1575.42 MHz

                 B3: 1268.52 MHz

Distinction two: use and characteristics

   GPS antenna

A.GPS is a one-way communication of a receiver-type positioning system, only broadcast signal, the user can do to do the positioning, GPS to solve a where I set

Problem, not limited by capacity.

   Compass antenna

B. Big Dipper is a two-way, both positioning and communication system, and the Big Dipper not only solved where I am, it also solve your where he is here,

Beidou user terminal is actually a transceiver function, and the Big Dipper is a transceiver function, its positioning needs to launch and then get the location, while its location

May pass to you can also pass to the people who care about you, in fact, the Big Dipper is a dual function of positioning and communication equipment, the user group is not the same,

Receiving the occasion is not the same. But there are capacity restrictions
