Analysis of The Current Status of Low-Orbit Satellites (LEO)
Generally, the deployable optical remote sensing antenna with X/Y type pedestal on the market have a variety of sizes ranging from 30 cm to several meters, and these antenna systems can support single-band and multi-band from L-band to Q-band. Today we introduce Antesky 1.8m S-band deployable optical remote sensing antenna.
This Antesky newly launched 1.8m X-Y deployable remote sensing antenna system 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.
As the technology develops, this X-Y pedestal design can be realized by light weight and compact size. Furthermore, there is no cable wrap issues and no need for rotary joints or slip rings. so that two persons will complete installation this 1.8m X-Y deploy-able antenna within 10 minutes.
The antenna 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.
Features of Antesky 1.8m X-Y deployable remote sensing antenna system
- 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.
