Iridium Satellite Frequency Range

Iridium communications owns and operates the constellation additionally selling equipment and access to its services it was originally conceived by bary bertiger raymond j.

Iridium satellite frequency range.

The iridium satellite constellation provides l band voice and data information coverage to satellite phones pagers and integrated transceivers over the entire earth surface. 1616 mhz 1626 5 mhz. With communications solutions ranging from satellite phones to broadband terminals iridium is trusted by more than a million mariners pilots humanitarians first responders and governments around the world. The iridium constellation consists of 66 low earth orbiting leo satellites primarily used for global communications.

This is the l band uplink downlink for the low earth orbit iridium satellite constellation. I q raw recording. With the variety of satellite frequency bands that can be used designations have been developed so that they can be referred to easily. Formerly iridium satellite llc is a publicly traded american company headquartered in mclean virginia iridium operates the iridium satellite constellation a system of 66 active satellites and 9 spares in space used for worldwide voice and data communication from hand held satellite phones and other transceiver units.

Between iridium phone terminal and iridium satellite. The iridium 9602 transceiver designed to be integrated into a wireless data application with other host system hardware and software provides a complete satellite iot data solution for your application. Between two iridium satellites. 23 18 to 23 38 ghz.

Only iridium offers truly global communications through a constellation of 66 crosslinked leo satellites. Iridium satellite frequency description. The satellites transmit in the l band at carrier frequencies in the range of 1616 1626 5 mhz using quadrature phase shift keying qpsk with a symbol rate of 25 000 symbols per second. 1616 mhz 1626 5 mhz.

The higher frequency bands typically give access to wider bandwidths but are also more susceptible to signal degradation due to rain fade the absorption of radio signals by atmospheric rain snow or ice. L band in the range from 1621 35 to 1626 5 mhz used for both uplink and downlink. Leopold and ken peterson in late 1987 in 1988.
