Description
What is an Underwater GPS Antenna?
The outdoor antenna Underwater GPS Antenna CTRF-ANTENNA-FB-1575-20256-SMA-3M is an Omnidirectional GPS antenna Passive GPS Antenna design, 3dBi gain passive GPS antenna, IP-68 rated waterproof antenna for GPS application antenna manufactured by C&T RF Antennas Inc for robust environment Underwater GPS Tracking Device.
The Underwater GPS Antenna is a passive GPS with an omnidirectional dipole design outdoor GPS antenna with an SMA connector RG174 cable extension. A 20x256mm antenna size, screw-mounted, through-hole mount, bracket mount, and terminal mount, are all accepted.
The same waterproof antenna radome fiberglass antenna mast we have is the marine 433Mhz antenna, 868MHz antenna, 915Mhz antenna, marine GPS antenna, marine wifi antenna, marine 4G antenna, etc.
Composition of the GPS system, ground monitoring, and GPS receiver tasks
GPS system composition
GPS space part: GPS satellite constellation
Functions
1. continuously send navigation and positioning signals to users with two infinite carriers
2. receive navigation messages and other information and send them to the general public in a timely manner
3. Receive the scheduling commands sent to the satellite by the ground control station through the injection station, correct the operational deviation or activate the backup clock in real-time, etc.
GPS ground control part: GPS ground monitoring system
A master control station.
Colorado, USA mainland. Collects and processes all information received from this station and monitoring stations, compiles the ephemeris and GPS time system for each satellite and transmits the predicted satellite ephemeris, clock differences, status data, and atmospheric propagation corrections into a navigation message to the injection station.
Three injection stations
Inject the navigation messages from the main control station into the memory of the corresponding satellite.
Five monitoring stations
Provide observation data from the satellites to the master control station
GPS user equipment part: GPS signal receivers
Capture the signals of the satellites to be measured selected by a certain satellite altitude cut-off angle and track the satellite operation
Transform, amplify, and process the received GPS signals
Measure the signal propagation time and decode the navigation messages sent by GPS satellites
Real-time calculation of the three-dimensional information of the station, and even three-speed and time.
System features
High positioning accuracy: up to 10-6 within 50km
Short observation time: relative static positioning within 20km takes only 15-20 minutes
No need for communication between stations: only the open sky over the stations is required.
3D coordinates, time, and velocity are available: classical geodesy measures plane and elevation separately, GPS can measure 3D coordinates of points at the same time.
Easy to operate
All-weather operation: 24-hour line.
