 Overview |
The alliance formed between France Télécom and Alcatel in order to study LEO (Low-Earth-Orbiting) constellations dates back to the late 1980s. Subsequently, France Télécom and Alcatel both participated in the initial work on Globalstar.
It was after the formation of Globalstar Limited Partnership, on March 24th 1994, that France Télécom and Alcatel decided to create a joint-venture called TE.SA.M.
TE.SA.M. was formally registered in July 1994, and the France Télécom and Alcatel Globalstar teams, which had until that time worked in geographically separated locations, came together as of January 1st 1996 on a single site in Paris and within a single corporation.
Today, we bear exclusive responsibility for the distribution of Globalstar services in 30 countries.
| What do we offer? |
In most of these countries we have created subsidiaries and partnerships with local cellular carriers to support the terrestrial cellular capabilities of our multimode phones and established distribution networks.
We have identified a number of key segments of our addressable market-place characterized by early expressions of interest in obtaining the service and by the potential for heavy usage of satellite airtime estimated to range between several hundred and 1,000 minutes per phone per month.
Whether you're in need of a satellite-based mobile phone for travel or a fixed phone for remote but flexible and economical on-site communication, Globalstar offers world-class products and services, including high quality voice, roaming and Short Messaging Service (SMS), and in the second half of year 2000 positioning, fax and data services up to 9,600 bps.
Globalstar's mobile phones, are only slightly larger than traditional cellular phones (actually much smaller and lighter than the first generation of mobile phones).
These phones are multi-mode and have the ability to work with terrestrial AMPS, CDMA, or GSM networks, as well as the Globalstar satellite network, according to the type of subscription.
Bi-mode and tri-mode terminals will switch between cellular mode and Globalstar mode, as soon as the subscriber moves out of cellular coverage, according to the programmable settings (user preferences). And of course, subscribers will be accessible in either mode from a single number.
Fixed phone products include models manufactured by Ericsson and Qualcomm, and public payphones option, built by Schlumberger.
A wide assortment of accessories, kits and services is also available for increased freedom in the field.
Terminals will be offered by local distributors according to the market and the deployment of existing networks.
The manufacturers for the first generation of terminals are: Ericsson (Sweden), Telit (Italy) and Qualcomm (USA).
The three manufacturers have received an aggregated (first) order totalling more than 250 000 terminals in May 1998 from Globalstar partners. TE.SA.M. has ordered over 60 000 teminals in for the initialization of service in its territories. The first terminals are available since end 1999.
| DUAL-MODE USER TERMINAL |
The Globalstar/GSM Dual-mode User Terminal offers a global roaming solution for GSM cellular phone users. Globalstar enhances wireless service options by providing worldwide GSM cellular-like services in areas like services in areas outside traditional cellular coverage. Inside the GSM service area, cellular coverage. Inside the GSM service area, a globalstar subscriber can continue to use the GSM services. Outside the GSM service area subscriber may roam to other GSM service area subscriber may roam to other GSM cellular networks or switch to the Globalstar network. Even in areas not served by cellular companies, subscribers are ensured of reliable, cost effective, World class mobile communication by Globalstar. The Globalstar constellation of Low Earth Orbit satellites will provide digitally crisp voice, data, and facsimile services. In all cases, interoperability between Globalstar and GSM is assured and subscribers maintain a convenient single point for billing.

| GLOBALSTAR SATELLITE CONSTELLATION |
The Globalstar constellation consists of 56 satellites, 48 of which are operational, with eight in-orbit spares. The satellites are placed in eight orbital planes of six satellites each, with a 1,414 kilometer circular orbit inclined at 52 degrees. The constellation was selected to provide the highest quality of service to the Earth's populated areas, 70 degrees North latitude to 70 degrees South. Any effect of signal delay and degradation are minimized by the Globalstar system's low Earth Orbit (LEO). Globalstar's LEO satellite constellation design reduces complexity and power requirements of user terminals and gateways, further minimizing costs to users and service providers. This means that user terminals are approximately the same size as a conventional cellular telephone.
The Globalstar system will maintain uninterrupted call capacity even when a satellite fails, due to multiple satellite coverage of a given region and by placing the in-orbit spares into operational orbit as needed so that they can be utilized. By contrast, a system utilizing geosynchronous satellites would suffer and entire regional system outage if an operational satellite were to fail. Further, by utilizing a combination of Code Division Multiple Access and spread spectrum technology, the Globalstar system maximizes use of spectrum while being able to share spectrum with other space-and terrestrial-based systems.
| FEATURES |
• 8 orbital planes, 6 satellites each
• 1414 km (758 nautical miles) at 52 degrees inclination
• 114-minute orbit period
• Multiple satellite coverage in temperate zones
• High signal quality and availability
| THE GLOBALSTAR SATELLITE |
The globalstar satellite is a simple low cost satellite designed to minimize both satellite and launch costs. Globalstar satellites do not directly connect one Globalstar user to another, rather, they relay communications between the user and a Gateway. Through this "bent-pipe" implementation, land based subscribers will be connected with the Public switching Telephone Network (PSTN) through the Gateway, thus maximizing the use of existing terrestrial telecommunications infrastructure. Globalstar provides an access technology delivering previously unavailable telephone traffic into the PSTN/PLMN operators terrestrial infrastructure.
The Globalstar satellite is three axis-stabalized and consists of a trapezoidal main body (configured to facilitate the launching of multiple satellites on one space launch vehicle), two deployable soar arrays, and deployable magnetometer on a boom. Unlike many geosynchrnous satellites, the antennas are not deployable. The satellite mass is approximately 450 kilograms and requires some 1,100 watts of power for normal operation. The satellites in the power for normal operation. The satellites in the first generation constellation are designed to operate at full performance for a minimum of 7.5 years.
| FEATURES |
• Simple, highly efficient and reliable "bent-pipe" transponders
• Small size and weight to reduce cost of launchers
• 48 satellites, 8 in-orbit spares
• Simple, existing, proven satellite technology
• State of the art manufacturing
• Strong satellite partner heritage
| GLOBALSTAR GATEWAY |
The Gateway interconnects the Globalstar satellite based wireless network and the PLMN, such as AMPS and GSM, or directly into the local telephone office (PSTN). As such, it is a termination point for network transmission and network signaling. The Gateway can be connected to existing PSTN using standard E1/T1 trunk supporting a variety of signaling protocols. To GSM networks, the Gateway appears as a GSM Base Station Subsystem. To those mobile switches in the EIA/TIA environment, it appears as another mobile switch supporting the IS-41 Intersystem Operation Standard. In all cases, inter-operability between Globalstar and telephone/cellular companies a convenient single point for billing.
The gateway is designed in a modular manner to provide flexibility in order to grow in step with market demand. The Globalstar Gateway can be shared by multiple service providers who can share investment in start-up common equipment. This design provides total security from other service providers sharing the gateway and expansion is planned as revenues rise.
