Globalstar Telecommunications
Globalstar, Inc. is an American satellite communications company that operates a low Earth orbit (LEO) satellite constellation for satellite phone and low-speed data communications. The Globalstar second-generation constellation consists of 24 low Earth orbiting (LEO) satellites. History The Globalstar project was launched in 1991 as a joint venture of Loral Corporation and Qualcomm. On March 24, 1994, the two sponsors announced the formation of Globalstar LP, a limited partnership established in the U.S., with financial participation from eight other companies, including Alcatel, AirTouch, Deutsche Aerospace, Hyundai, and Vodafone. At that time, the company predicted the system would launch in 1998, based on an investment of $1.8 billion. Globalstar received its US spectrum allocation from the FCC in January 1995 and continued to negotiate with other nations for rights to use the same radio frequencies in their countries. The first satellites were launched in February 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telephone Call
A telephone call is a connection over a telephone network A telephone network is a telecommunications network that connects telephones, which allows telephone calls between two or more parties, as well as newer features such as fax and internet. The idea was revolutionized in the 1920s, as more and more ... between the called party and the calling party. First telephone call The first telephone call was made on March 10, 1876, by Alexander Graham Bell. Bell demonstrated his ability to "talk with electricity" by transmitting a call to his assistant, Thomas Watson. The first words transmitted were "Mr Watson, come here. I want to see you." This event has been called Bell's "greatest success", as it demonstrated the first successful use of the telephone. Although it was his greatest success, he refused to have a telephone in his own home because it was something he invented by mistake and saw it as a distraction from his main studies. Information transmission A telephone cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navigation
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.Bowditch, 2003:799. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. History In the European medieval period, navigation was considered part of the set of '' seven mechanical arts'', none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open-ocean navigation; it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPOT Satellite Messenger
SPOT is a GPS tracking device that uses the Globalstar satellite network to provide text messaging and GPS tracking (depending on the subscription type purchased). It has a coverage area that includes a large portion of the planet, with the exception of extreme northern and southern latitudes and parts of the Pacific Ocean. Depending on the product, SPOT can send and receive communications. The device is sold by SPOT LLC, a subsidiary of Globalstar. With the purchase of a subscription, SPOT allows short (41 character) user-defined text messages which can be sent to a list of telephone numbers and e-mail addresses. This subscription also allows users to push their location to emergency services. Users can share their location and messages based on their account preference, alerting friends and family to their whereabouts. In early 2018, SPOT launched the SPOT X, a two-way satellite messaging device with GPS location tracking, navigation Navigation is a field of study that foc ...

SCADA
Supervisory control and data acquisition (SCADA) is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes. It also covers sensors and other devices, such as programmable logic controllers, which interface with process plant or machinery. Explanation The operator interfaces which enable monitoring and the issuing of process commands, like controller set point changes, are handled through the SCADA computer system. The subordinated operations, e.g. the real-time control logic or controller calculations, are performed by networked modules connected to the field sensors and actuators. The SCADA concept was developed to be a universal means of remote-access to a variety of local control modules, which could be from different manufacturers and allowing access through standard automation protocols. In practice, large SCADA systems have grown to become very similar to distr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Station
A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources. Ground stations may be located either on the surface of the Earth, or in its atmosphere. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands (e.g. microwaves). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link. A principal telecommunications device of the ground station is the parabolic antenna. Ground stations may have either a fixed or itinerant position. Article 1 § III of the International Telecommunication Union (ITU) Radio Regulations describes various types of stationary and mobile ground stations, and their interre ...

Ericsson R290
The Ericsson R290 is a combined GSM and satellite phone using the Globalstar satellite network. The R290 was introduced in June 1999 and manufactured in the United Kingdom by Ericsson Mobile Communications. The Globalstar uses a foldable antenna that is the same length as the body of the telephone. The R290 comes in a blue and black case in a style similar to other Ericsson phones of its period. The case incorporates some Gore-Tex weatherproofing, similar to that used in the Ericsson R310s, although less extensive. The R290 also has a built-in modem for data and fax communication at 9.6 kbit/s in GSM mode and 7.2 kbit/s in satellite mode. The R290 is somewhat larger than typical, pure GSM phones, measuring × × and weighing (with slim battery). The R290 has relatively brief battery life compared with typical, pure GSM phones of its generation. Because it uses a non-standard battery voltage, its charging connector is not one of the types commonly seen on other Ericsson han ...

Chapter 11, Title 11, United States Code
Chapter 11 of the United States Bankruptcy Code (Title 11 of the United States Code) permits reorganization under the bankruptcy laws of the United States. Such reorganization, known as Chapter 11 bankruptcy, is available to every business, whether organized as a corporation, partnership or sole proprietorship, and to individuals, although it is most prominently used by corporate entities. In contrast, Chapter 7 governs the process of a liquidation bankruptcy, though liquidation may also occur under Chapter 11; while Chapter 13 provides a reorganization process for the majority of private individuals. Chapter 11 overview When a business is unable to service its debt or pay its creditors, the business or its creditors can file with a federal bankruptcy court for protection under either Chapter 7 or Chapter 11. In Chapter 7, the business ceases operations, a trustee sells all of its assets, and then distributes the proceeds to its creditors. Any residual amount is returned to the ...
