Responses to Building An Active RFID People Asset Tracking System With Mesh Networking RFID tracking system Hack a Day Says February 21st, 2010 at 12. This tutorial will show you step by step ways how you can perform serial port communication operation in your c application with necessary code examples. In computing, a serial port is a serial communication interface through which information transfers in or out one bit at a time in contrast to a parallel port. Share Your Weather Data. Create Your Own Reports. Data can be exported to most popular spreadsheets, databases, and word processing programs. Weather Website. Omniflex designs and manufactures electronic products for the automation and control industry worldwide, specialising in remote monitoring, industrial networking. PRPS Patent Review Processing System is the Boards efiling EF and case management CM system for trial proceedings has been retired on Dec. In general, a satellite is anything that orbits something else, as, for example, the moon orbits the earth. In a communications context, a satellite is a specialized. What is satellite Definition from What. Is. com. In general, a satellite is anything that orbits something else, as, for example, the moon orbits the earth. In a communications context, a satellite is a specialized wireless receivertransmitter that is launched by a rocket and placed in orbit around the earth. There are hundreds of satellites currently in operation. They are used for such diverse purposes as weather forecasting, television broadcast, amateur radio communications, Internet communications, and the Global Positioning System, GPS.

The first artificial satellite, launched by Russia then known as the Soviet Union in the late 1. It did nothing but transmit a simple Morse code signal over and over. In contrast, modern satellites can receive and re transmit thousands of signals simultaneously, from simple digital data to the most complex television programming. There are three types of communications satellite systems. They are categorized according to the type of orbit they follow.

A geostationary satellite orbits the earth directly over the equator, approximately 2. At this altitude, one complete trip around the earth relative to the sun takes 2. Thus, the satellite remains over the same spot on the earths surface at all times, and stays fixed in the sky from any point on the surface from which it can be seen. So called weather satellites are usually of this type. You can view images from some of these satellites on the Internet via the Purdue Weather Processor. A single geostationary satellite can see approximately 4. Three such satellites, spaced at equal intervals 1. A geostationary satellite can be accessed using a dish antenna aimed at the spot in the sky where the satellite hovers. A low earth orbit LEO satellite system employs a large fleet of birds, each in a circular orbit at a constant altitude of a few hundred miles. The orbits take the satellites over, or nearly over, the geographic poles. Each revolution takes approximately 9. Igi 7 Game. The fleet is arranged in such a way that, from any point on the surface at any time, at least one satellite is on a line of sight.

The main difference is that the transponders, or wireless receivertransmitters, are moving rather than fixed, and are in space rather than on the earth. A well designed LEO system makes it possible for anyone to access the Internet via wireless from any point on the planet, using an antenna no more sophisticated than old fashioned television rabbit ears. Some satellites revolve around the earth in elliptical orbits. These satellites move rapidly when they are near perigee, or their lowest altitude they move slowly when they are near apogee, or their highest altitude. Such birds are used by amateur radio operators, and by some commercial and government services. They require directional antennas whose orientation must be constantly adjusted to follow the satellites path across the sky.
