An antenna is a device for radiating or receiving radio signals. An antenna that transmits signals does so by converting electrical current into electromagnetic radio waves. An antenna that receives signals does so by converting electromagnetic waves back into electric current. An antenna map is an ...
The three segments of GPS are: Space (Satellites) — The satellites circling the Earth, transmitting signals to users on geographical position and time of day. Ground control — The Control Segment is made up of Earth-based monitor stations, master control stations and ground antenna. Control ac...
GPS is currently used in all walks of life. As long as there are items to be used that need to provide positioning and map functions, they must be installed. With GPS, what are the requirements for GPS antenna installation? What precautions should we know during installation?
In addition to the GPS receiver that computes your PNT, the next most important piece of technology is your antenna. AGPS/GNSS antennaacts as a gatekeeper to ensure only high-quality satellite signals are received for accurate calculations. These calculations are supplemented withGNSS/GPS correction...
AGPS AGPS technology is a combination of mobile station positioning network base station information and GPS information technology, can be used in GSM/GPRS, WCDMA and CDMA2000 network. The technology needs to increase the GPS receiver module in the handset, and to transform the handset antenna, ...
A global positioning system (GPS) telescope is an astronomy device that combines a standard telescope with GPS technology. This unique combination allows astronomers to locate constellations and other celestial objects quickly and easily. GPS telescopes are also known as "goto" or "auto" scopes. ...
This insight article on GPS / GNSS spoofing explains what spoofing is and how to make your GPS / GNSS receiver secure against spoofing.
GPS can provide worldwide, three-dimensional positions, 24 hours a day, in any type of weather. However, the system does have some limitations. There must be a relatively clear “line of sight” between the GPS antenna and four or more satellites. Objects, such as buildings, overpasses, an...
