GPS over fiber

Best GPS over Fiber Optic Equipment

GPS and Fiber basic information

The Global Positioning System (GPS), officially NAVSTAR GPS, is a global navigation satellite system for positioning. It was developed by the US Department of Defense since the 1970s and replaced from about 1985, the old satellite navigation system NNSS (Transit) of the US Navy, as well as the Vela satellites for the detection of nuclear weapon explosions. GPS has been fully operational since the mid-1990s, and has allowed civilian users to achieve accuracy levels well beyond 10 meters since the shutdown of Artificial Selective Availability (2 May 2000). Accuracy can be increased to centimeter-range or better by using differential methods (differential GPS / DGPS) around a reference receiver. The satellite-based Enhancement Systems (SBAS), which distribute correction data over geostationary satellites that are not receivable in the Polar Regions and also belong to the class of DGPS systems, achieve continent-wide accuracies of one meter. GPS has established itself as the world's most important location method and is widely used in navigation systems.
 

For technical reasons, the accuracy of calculating altitude is about 3 times lower than latitude and longitude. This is due to the geometry of the spatial notch used to determine the position. The quality of position specifying is determined by DOP (Dilution Of Precision) precision blur parameters.
 

GPS receivers have many functions, including:

  • determination of coordinates according to different coordinate systems (standard WGS 84);
  • logging of the trace;
  • "to point" and "route" navigation;
  • track back (i.e. return to the place of departure "same route");
  • distance measurement;
  • determination of area (e.g. plot);
  • calculating the moments of sunrise and sunset and the phases of the moon.

And in more extensive receivers:

  • map display and navigation on layered maps;
  • communication via serial port (RS232 / USB) and Bluetooth with other electronic equipment (PC, PPC, Palm, electronic sea chart ECDIS);
  • auto routing (setting the automatic route "on the roads").

 


For simultaneous reception of a signal from several satellites or a two-frequency signal from one satellite, receivers of two types are used:
 

  • Multi-channel - these receivers consist of a defined number of independent channels and each of them is adapted to receive and process signals from one satellite. Signal reception and processing processes are carried out in such a multi-channel receiver at the same time. Observations can be made with a second frequency;
  • Multi-plexing - these receivers consist of one or more channels, each of which can receive individual signals from satellites. Observations are made with a millisecond frequency. The best quality signal is provided by the multi-channel correlation type receivers. Squaring type receivers square both signals and noise.


The scope and method of operation, the multiplicity and versatility of applications, reliability and usefulness in everyday life cause that devices using GPS are really, commonly used, often in a very unconventional way, and the new positioning systems that are already in the implementation phase, with even greater capabilities make devices to support and service the GPS systems very popular and widely used. Among the key suppliers of supplementary equipment there is - of course - Thor Broadcast with their interesting proposals.
