LEO Satellite System for Remote Sensing

Low Earth Orbit(LEO) satellite system with remote sensing generally refers to a satellite system composed of multiple satellites that can perform real-time information processing. The low-orbiting satellite (1000~5000km from the ground) takes a short time around the earth, usually 2~4 hours. With the characteristics of easy to obtain high-resolution images of targets, low-orbit satellites are generally…

Application for Remote Sensing Antenna

Remote sensing is a general term for a comprehensive technical system for observing the Earth and celestial bodies from the ground to the upper air. It consists of remote sensing platform, remote sensing instrument, and information receiving, processing and analysis applications. They provides people with rich scientific data and dynamic intelligence day and night. The…

Features of X-band X/Y Type Pedestal Ground Station

X/Y type pedestal for remote sensing: The pointing accuracy of antenna pedestal is a core factor for antenna capturing and tracking satellite. In order to realize the whole process of no-blind area tracking of special-purpose satellites such as resource satellites, it is necessary to solve the problem of over-top tracking. X/Y type pedestal design is a…

How to Distinguish LHCP and RHCP of Circular Polarization?

Before distinguish LHCP and RHCP of Circular Polarization. It is better to know Circular Polarization Wave. 1. What is Circular Polarization Wave? The instantaneous orientation of its electric field vector during a wave propagates in space is called polarization. If the track of electric field vector in space is a circle. That is, the electric field vector…
