1. Overview of 2.4m S-band Remote Sensing Antenna
This 2.4m X-Y deployable remote sensing antenna system with model of ATSK-S240, is one of Antesky newly launched products, which adopts X-Y pedestal, which eliminates the keyhole at zenith and backlash problems compared with traditional AZ/EL pedestal of the tracking antenna. It is to track LEO and MEO satellites.
ATSK-S240 2.4m S band remote sensing antenna system adopts a modular design, which is convenient for combatants to carry on maneuver and can be quickly erected and opened for business under complicated working conditions. The turntable adopts an X-Y mount with electric polarization adjustment. The final stage of the automatic antenna transmission is equipped with an absolute encoder. With precise servo control technology, it can track synchronous orbit satellites and polar orbit satellites in a variety of harsh environments. The antenna system covers L, S, C, X, Ku, Ka and other frequency bands, which can be used for data transmission or electromagnetic signal reconnaissance.
2. Key Features of 2.4m S-band Remote Sensing Antenna
- The key components of the antenna are made of carbon fiber composite material, which has stable performance and light weight.No need to heat the dish to avoid expansion and contraction as temperatures change; greater gain performance over an aluminum dish, especially at the higher Ka-band through V-band ranges. Heated reflectors for ice and snow removal are available.
- The antenna adopts the feed-forward feed, which has the advantages of high gain, low sidelobe, and high efficiency.
- The antenna adopts program guidance and automatic tracking.
- The antenna system is equipped with GPS equipment, which can provide accurate time and terminal location, with a pointing accuracy of less than 0.1 degrees.
- The sophisticated antenna design does not require a lot of maintenance than a fixed ground station.It also offers deployable antennas that can pack into a set of flight cases, which are well-suited for temporary and military applications.
- Environmental Resilience: System designed for operation in coastal, arctic, and desert environments.
