Telecommunications system
System architecture Globalstar differs from Iridium in several important ways: - Globalstar satellites are simple "bent pipe" repeaters; there is no inter-satellite linking. A network of ground gateway stations provides connectivity from the 40 satellites to the public switched telephone network; users are assigned telephone numbers on the North American Numbering Plan in North America or the appropriate telephone numbering plan for the country that the overseas gateway is located in, except for Brazil, where the official Globalstar country code (+8818) is used. Because there is no inter-satellite linking, a satellite must have a gateway station in view to provide service to any users it may see. Because there are no gateway stations to cover certain remote areas (such as oceans areas far from land), no service can be provided in those areas even though the satellites fly over them.
- Globalstar orbits have an inclination of 52 degrees, compared to the near-polar 86.4-degree orbits used by Iridium. Globalstar also does not cover polar areas due to the lower orbital inclination.
- The Globalstar system uses the Qualcomm CDMA air interface; however, the Ericsson and Telit phones accept standard GSM SIM cards, while the Qualcomm GSP-1600/1700 phones do not have a SIM card interface, but use CDMA/IS-41 based authentication. Therefore the Globalstar gateways need to support both the CDMA/IS-41 and the GSM standards, which not all gateways do. This results in the lack of coverage for GSM authentication based phones in the Eastern Asian and Caribbean region, as stated on the coverage map: [1]
While for Iridium only Telstra Australia offers GSM-roaming, most Globalstar providers have roaming agreements with local cellular operators, enabling the use of a cellular SIM card with a Globalstar handset and vice versa. In telecommunications, the term gateway has the following meanings: In a communications network, a network node equipped for interfacing with another network that uses different protocols. ...

Despite (or because of) the limitations above, Globalstar’s operational costs were significantly cheaper and can support somewhat higher data rates than Iridium. However, such cost differences later proved meaningless when both companies shed their multi-billion dollar debts through bankruptcy. Notice of closure stuck on the door of a computer store the day after its parent company, Granville Technology Group Ltd, declared bankruptcy (strictly, put into administration—see text) in the United Kingdom. ...
System deployment Like Iridium, Globalstar received its U.S. spectrum allocation from the FCC in January 1995, and continued to negotiate with various other sovereign nations for rights to use the same radio frequencies in their countries. FCC redirects here. ...

In October 1999, the system began "friendly user" trials with 44 of 48 planned satellites. In December 1999, the system began limited commercial service (200 users) with the full 48 satellites (no spares in orbit). In February 2000, it began full commercial service with its 48 satellites and 4 spares in North America, Europe and Brazil. Initial prices were $1.79/minute vs. $9/minute for Iridium.

Recent problems According to documents filed with the SEC on January 30, 2007, Globalstar's previously identified problems with its S-band amplifiers used on its satellites for two-way communications are occurring at a rate faster than previously believed, possibly eventually leading to total loss of service in 2008. SEC redirects here. ...
The S band ranges from 2 to 4 GHz. ...
In the filing, Globalstar made the following statements:
"Based on data recently collected from satellite operations, the Company has concluded that the degradation of the amplifiers is now occurring at a rate that is faster than previously experienced and faster than the Company had previously anticipated." "Based on its most recent analysis, the Company now believes that, if the degradation of the S-band antenna amplifiers continues at the current rate or further accelerates, and if the Company is unsuccessful in developing additional technical solutions, the quality of two-way communications services will decline, and by some time in 2008 substantially all of the Company’s currently in-orbit satellites will cease to be able to support two-way communications services." [3] Industry analysts speculate the problem is caused by radiation exposure the satellites receive when they pass through the South Atlantic Anomaly in their 876 mile (1414 km) altitude orbits.[1] The Van Allen radiation belts and the point of the South Atlantic Anomaly. ...
"The S-band antenna amplifier degradation does not affect adversely the Company’s one-way “Simplex” data transmission services, which utilize only the L-band uplink from a subscriber’s “Simplex” terminal to the satellites. " [4] "The Company is working on plans, including new products and services and pricing programs, and exploring the feasibility of accelerating procurement and launch of its second-generation satellite constellation, to attempt to reduce the effects of this problem upon its customers and operations. The Company will be able to forecast the duration of service coverage at any particular location in its service area and intends to make this information available without charge to its service providers, including its wholly owned operating subsidiaries, so that they may work with their subscribers to reduce the impact of the degradation in service quality in their respective service areas. The Company is also reviewing its business plan in light of these developments. " [5] "The Company’s liquidity remains strong. At December 31, 2006, in addition to its credit agreement, the Company had unrestricted cash on hand and undrawn amounts under the Thermo Funding Company irrevocable standby stock purchase agreement of approximately $195 million." [6]
Globalstar's Interim Solution On 18 April 2007 Globalstar announced they would launch eight spare satellites to augment the company’s existing first-generation LEO satellite constellation.[2] On 29 May 2007 the first four of these satellites were launched by Starsem from the Baikonur Cosmodrome in Kazakhstan atop a Soyuz-FG/Fregat rocket. The second launch, also aboard a Soyuz-FG/Fregat from Baikonur, was launched on 2007-10-20.[3] is the 108th day of the year (109th in leap years) in the Gregorian calendar. ...

However, it is still not clear when the new satellites will improve phone communications. The Globalstar website is mute on this issue. Most current users in summer 2007 report difficulty using the phones, with very short communication windows of 1–2 minutes and frequently dropped calls[citation needed]. In addition, an offshore fishing magazine (Big Game Fishing Journal) wrote an editorial in their July 2007 issue on the poor service of Globalstar [7].
Globalstar's Second-Generation of Satellite Constellation In December 2006, Globalstar announced that Alcatel Alenia Space has been awarded a EUR 661 million contract for the second-generation 48 satellite constellation. [8] Year 2006 (MMVI) was a common year starting on Sunday of the Gregorian calendar. ...
Alcatel Alenia Space was established on July 1 2005 by the merger of Alcatel Space and Alenia Spazio and is owned by Alcatel (67%) and Finmeccanica (33%). The company is Europes largest satellite manufacturer. ...
"The satellites are being designed with a life expectancy of 15 years, which is significantly longer than the design life of Globalstar’s first generation constellation." In addition, Globalstar announced on April, 03, 2007 that it has signed a EUR 9 million (approximately US$ 12 million) agreement with Alcatel Alenia Space to upgrade the Globalstar satellite constellation, including necessary hardware and software upgrades to Globalstar’s satellite control network facilities. [9] "This second-generation of satellites are expected to provide service to Globalstar customers with satellite voice and data services until at least 2025."
