3-axis X-Y Pedestal for LEO/MEO Tracking Ka-band Antenna : A very unique and efficient pedestal design, that has been optimized for tracking LEO satellite on ka-band frequency. It has a novel three axis geometry that not only provides for full hemispherical coverage but also assures that during tracking. The system never comes closer than 45 degrees to a keyhole. This leads to the lowest possible axis speeds and…
How to choose a mount for tracking LEO Satellites for Ka band antenna system. A low Earth orbit (LEO) is an orbit around Earth with an altitude above Earth’s surface of 2,000 kilometers (1,200mi), and an orbital period between about 84 and 127 minutes. Objects below approximately 160 kilometers (99mi) will experience very rapid orbital decay and…
Frequency Band used for Weather Satellite Receiving System include L-band, C-band, Ku-band and Ka-band etc. The diagram of communication wavelength bands is shown below: L-Band (1-2 GHz) As a relatively low frequency, the L-band is easier to handle, requires less complex and inexpensive RF devices, and because of the wider beam width, the antenna’s…
Meteorological satellites are artificial earth satellites that perform meteorological observations of the Earth and its atmosphere from space. The satellite carries a variety of meteorological remote sensors that receive and measure visible, infrared and microwave radiation from the Earth and its atmosphere and convert it into electrical signals for transmission to ground stations which restores…
Meteorological satellites, also called Weather satellite, are mainly used for weather analysis and forecasting, numerical weather prediction, climate monitoring and prediction, ecological and environmental monitoring, especially in the monitoring and warning of severe cyclone and mesoscale severe convective weather, and meteorological satellites can also be used for Earth observation and scientific experimental satellites. The meteorological…
