LEO is an orbit around the Earth, which is at least 1000km above the Earth’s surface and has an orbital period of about 84-127 minutes. Objects below about 160 km (99 miles) will experience very fast orbital attenuation and height loss. The traditional commercial satellite is the GEO satellite which are fixed on the GEO belt…
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…
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…
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…
