The US National Oceanographic and Atmospheric Administration (NOAA) operate both Geostationary Orbits (GEO) and Low Earth Orbiter (LEO) polar satellites. The LEO weather satellites orbit from pole to pole, which allows them to pass over most areas on earth at least once within a given time. They constantly move relative to the earth’s surface so are close enough to obtain sharp pictures of what they see below them. These satellites typically follow an orbit of a few hundred to a couple of thousand kilometers in altitude. Weather satellites can generally be categorized as Low Earth Orbiters (LEO).

Likewise, freeware is also available to decode the signal received from the satellite into images that will be displayed on the PC monitor

There is an extensive list of free software packages that would facilitate the tracking of these satellites. To be able to tune to the correct signal frequency, it is necessary to track the desired satellite. The soundcard is the A/D demodulating interface, while appropriate image display software on the PC is used to view the images. The most popular means of decoding weather satellite transmissions and creating images these days is accomplished by means of a personal computer (PC) and a soundcard. The receiver must have the capability to tune to these frequencies. In order to acquire these signals, a modified FM receiver has to be employed. In the same way, NOAA satellites transmit radio frequencies that range from 137 to 138 MHz. The antenna will be designed to capture the operating frequencies of NOAA and Russian Meteor satellites in addition the antenna has to work with the receiver. There are two common solutions to this problem, the crossed dipole and the quadrifilar helix (QFH) antenna. The signals from the NOAA weather satellites are transmitted with right-hand circular polarization. The objective is to get weather images broadcasted by American NOAA and Russian Meteor satellites for which, the development of system composed of an antenna with a very high gain, and a receiver capable of processing signals in the range of 137 MHz will be required. The development, design, and construction of a fully functional home weather satellite receiver station will be attempted. This project was completed for my Senior Design Project along with two other members. In addition, an antenna for the 137 MHz range had to be designed. This home weather satellite receiver is a system of an FM receiver tunable to NOAA weather satellite frequencies (137 to 138 MHz) interfaced with a PC.
