What is automatic Tracking Antenna?
Delivering high throughput at long ranges, the Auto-Tracking Antenna System from Persistent Systems is a deployable unit that works in concert with the MPU5 radio, keeping constant communication from air to ground. Long range high throughput communication to manned and unmanned aircraft has never been so simple.
What is an antenna tracker?
Antenna Trackers are systems that track your vehicle’s location, and use this information to correctly align a directional antenna. This approach significantly improves the range over which signals can be both sent and received from the ground station.
What are secondary antennas?
A secondary antenna has a greater beam width than the primary antenna and receives the same tracking signal from the satellite. The signal strength signals from the two antennas are input to a summation function which takes the difference of the two signals.
How do antenna trackers work?
An antenna tracking system tracks a primary antenna to follow a moving signal source, such as a communication satellite. The signal strength signals from the two antennas are input to a summation function which takes the difference of the two signals.
Which antenna is used for satellite tracking system?
Wire antennas were used on the early operational satellites such as INTELSAT I and II with an antenna gain of about 4 dBi for receive and about 9 dBi for transmit. Now they are mostly used as the tracking, telemetry, and command (TT&C) antennas because of their wide beamwidth.
How does antenna control unit work?
An antenna control unit utilizes the resulting difference signal to select the optimum signal strength for the particular step of the search pattern. This system is particularly applicable to extremely high frequency communication channels (86 GHz and above) which are subject to atmospheric distortion and noise.
What is Ula antenna?
A Uniform Linear Array (ULA) is a collection of sensor elements equally spaced along a straight line. The most common type of sensor is a dipole antenna that can transmit and receive Electromagnetic Waves over the air. Other types of sensors include acoustic sensors that may be used in air or under water.
How do antennas track satellites?
Why a helical antenna is used for satellite tracking?
In helical antenna, the diameter and pitch of the helix are comparable to a wavelength. The antenna functions as a directional antenna radiating a beam off the ends of the helix. It radiates circularly polarized radio waves. These are used for satellite communication.
