The Iridium system was designed to be accessed by small handheld phones, the size of a cell phone. While "the weight of a typical cell phone in the early 1990s was 10.5 ounces" [6] (300 grams) Advertising Age wrote in mid 1999 that "when its phone debuted, weighing 1 pound (453 grams) and costing $3,000, it was viewed as both unwieldly and expensive."
Iridium Communications Inc. (formerly Iridium Satellite LLC) is a publicly traded American company headquartered in McLean, Virginia, United States. Iridium operates the Iridium satellite constellation , a system of 80 satellites: 66 are active satellites and the remaining fourteen function as in-orbit spares. [ 2 ]
The Iridium system has 66 satellites, which orbital inclination of 86.4° and inter-satellite links provide service availability over the entire surface of Earth. Starlink is a satellite internet constellation operated by SpaceX , that aims for global satellite Internet access coverage.
Leveraging upgraded satellite constellation, the new broadband service offering is likely to fortify Iridium's (IRDM) market presence with improved maritime and land-mobile applications.
Most commercial voice and some data mobile satellite services are provided by systems operating in the L-band by Iridium, Inmarsat, Globalstar and Thuraya.The L-band spectrum allocated for MSS is between 1.5 and 2.5 GHz, with the upper portion often referred to as the S-band.
Iridium 33 was a communications satellite launched by Russia for Iridium Communications. It was launched into low Earth orbit from Site 81/23 at the Baikonur Cosmodrome at 01:36 UTC on 14 September 1997, by a Proton-K rocket with a Block DM2 upper stage. [2] [3] The launch was arranged by International Launch Services (ILS).

This satellite had been deactivated prior to the collision, and remained in orbit as space debris. The other spacecraft, Iridium 33, was a 560-kilogram (1,200 lb) U.S.-built commercial satellite that was part of the Iridium constellation for satellite phones. [2] It was launched on September 14, 1997, atop a Russian Proton rocket.
