5.4m Ka Band LEO Satellite Communication Antenna
- DESCRIPTION
- TECHNICAL
- SPECIFICATIONS
RSA54X / Y-Ka model 5.4m antenna is designed for Ka-band LEO satellite communication. The antenna is in the form of dual shaped Cassegrain antenna. The main reflector is divided into 12 panels, made with aluminum honeycomb sandwich structure in negative pressure molding process. It has high accuracy, low weight and high temperature stability. The feed is multi-mode corrugated horn TE21 mode monopulse automatic tracking feed, have high antenna efficiency and tracking accuracy.
The antenna pedestal is in X / Y type. It is the key performing mechanism to achieve non-blind tracking in zenith. Each axis rotation range is ± 90˚, can cover the entire airspace, effectively avoid coiling and collector ring problem in Az/El structure. The large-size final drive has high structural rigidity ensured the antenna pointing accuracy, tracking accuracy and rotation stability of the overall structure.
Probecom offer Remote satellite sensing antenna, Remote sensing data receiving system, Vechile mounting remote sensing station, Vechile carrier remote sensing station.
The main functions:
a) Have monopulse auto tracking, program tracking and external data guide tracking modes.
b) Have time offset adjustment and X, Y axis angle adjustment function in program tracking mode.
c) Have angle measurement data acquisition function in auto tracking mode;
d) Can be connected via a network interface or RS-232 serial interface with system monitoring computer, monitors the parameter configuration of antenna system, control and equipment status.
