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.
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.

It is worth pointing out that this X-Y motor pointing mechanism behind the dish is particularly attractive for operations with satellites in low earth orbit (LEO) or medium earth orbit (MEO) as these satellite move across the sky and often move almost overhead. This X-Y mechanism enable smooth following.

The traditional elevation over azimuth mount is unable to follow such overhead passes without impossibly rapid azimuth rotation through 180 deg in just one second !
