In addition to GPS for navigation, positioning and measurement, since the
precise clock on the space satellite of the GPS system can release time and
frequency information, based on the precise clock on the space satellite, under
the monitoring of the ground monitoring station, transmission Precise time and
frequency is another important application of GPS, which can be used to control
precise time or frequency and serve many engineering experiments. In addition,
GPS can also be used to obtain meteorological data for some experimental and
engineering applications.
The global satellite positioning system GPS is one of the most innovative
high-tech developed this year. Its global, omnipotent, all-weather navigation
and positioning, timing, and speed measurement advantages will inevitably be
more and more widely used in many fields. Applications. In developed countries,
GPS technology has been applied to transportation and traffic engineering. At
present, the application of GPS technology in China's road engineering and
traffic management has just started. With the development of China's economy,
the rapid construction of high-grade highways and the gradual deepening of the
application of GPS technology, its application in road engineering will also be
Broader and deeper, and play a bigger role.
Data interface format: This needs to be discussed in detail. GPS can output
real-time positioning data for other devices to use, which involves a data
exchange protocol. Almost all GPS receivers now follow the standard
specification specified by the National Marine Electronics Association, which
establishes the communication standard between all marine electronic
instruments, including the format of transmission data and the communication of
transmission data. protocol. There are three types of NMEA protocols: 0180, 0182
and 0183. 0183 can be considered as a superset of the first two and is now
widely used. 0183 has several versions, V1.5 V2.1. Therefore, if your GPS
receiver is to be connected to a common GPS navigation program in your notebook,
such as OZIEXPLORER and my GPSRECEIVER, you should choose the protocol above
NEMA V2.0. The communication speed specified by NMEA is 4800 b/S. There are now
receivers that offer higher speeds too, but honestly it's not much use, 4800 is
more than enough.
