Telemetry is the in situ collection of measurements or other data at remote points and their automatic transmission to receiving equipment (telecommunication) for monitoring. The word is derived from the Greek roots tele, 'remote', and metron, 'measure'. Systems that need external instructions and data to operate require the counterpart of telemetry: telecommand.
Iridium Communications Inc. is a publicly traded American company headquartered in McLean, Virginia, United States. Iridium operates the Iridium satellite constellation, a system of 75 satellites: 66 are active satellites and the remaining nine function as in-orbit spares. Iridium Satellites are used for worldwide voice and data communication from handheld satellite phones, satellite messenger communication devices and integrated transceivers, as well as for two-way satellite messaging service from supported conventional mobile phones. The nearly polar orbit and communication between satellites via inter-satellite links provide global service availability.
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.
A mobile data terminal (MDT) or mobile digital computer (MDC) is a computerized device used in emergency services, public transport, taxicabs, package delivery, roadside assistance, and logistics, among other fields, to communicate with a central dispatcher. They are also used to display mapping and information relevant to the tasks and actions performed by the vehicle such as CAD drawings, diagrams and safety information.
A satellite telephone, satellite phone or satphone is a type of mobile phone that connects to other phones or the telephone network by radio link through satellites orbiting the Earth instead of terrestrial cell sites, as cellphones do. Therefore, they can work in most geographic locations on the Earth's surface, as long as open sky and the line-of-sight between the phone and the satellite are provided. Depending on the architecture of a particular system, coverage may include the entire Earth or only specific regions. Satellite phones provide similar functionality to terrestrial mobile telephones; voice calling, text messaging, and low-bandwidth Internet access are supported through most systems. The advantage of a satellite phone is that it can be used in such regions where local terrestrial communication infrastructures, such as landline and cellular networks, are not available.
Satellite Internet access is Internet access provided through communication satellites; if it can sustain high speeds, it is termed satellite broadband. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using Ku band to achieve downstream data speeds up to 506 Mbit/s. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space.
Telematics is an interdisciplinary field encompassing telecommunications, vehicular technologies, electrical engineering, and computer science. Telematics can involve any of the following:
Kenwood is a Japanese brand of consumer electronics. It has been owned by JVCKenwood since October 2011, when Kenwood Corporation merged with JVC. Kenwood manufactures audio equipment such as AM/FM stereo receivers, cassette tape decks/recorders, amateur radio (ham) equipment, radios, cellular phones, speakers, and other consumer electronics.
The Broadband Global Area Network (BGAN) is a global satellite network with telephony owned by Inmarsat using portable terminals. The terminals are normally used to connect a laptop computer to broadband Internet in remote locations, although as long as line-of-sight to the satellite exists, the terminal can be used anywhere. The value of BGAN terminals is that, unlike other satellite Internet services, which require bulky and heavy satellite dishes to connect, a BGAN terminal is about the size of a laptop and thus can be carried easily. The network is provided by Inmarsat and uses three geostationary satellites called I-4 to provide almost global coverage.
ORBCOMM is an American company that offers industrial internet and machine to machine (M2M) communications hardware, software and services designed to track, monitor, and control fixed and mobile assets in markets including transportation, heavy equipment, maritime, oil and gas, utilities and government. The company provides hardware devices, modems, web applications, and data services delivered over multiple satellite and cellular networks.
Machine to machine (M2M) is direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the information it records to application software that can use it. Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer.
Free Wave Technologies, Inc. designs and manufactures secure machine-to-machine wireless networking, communications, and computing systems. Their radios can capture and transmit data from devices such as sensors, gauges, valves, robots, drones, and unmanned vehicles over long distances in clear line-of-sight environments and harsh environments. Free Wave's radios support a variety of industrial applications, such as supervisory control and data acquisition (SCADA), wireless I/O, cathodic protection (CP), remote monitoring, telemetry, and analytics. Free Wave can provide long range, reliable and rugged wireless data links through both licensed and license-free radios.
Sierra Wireless is a Canadian multinational wireless communications equipment designer, manufacturer and services provider headquartered in Richmond, British Columbia, Canada. It also maintains offices and operations in the United States, Korea, Japan, Taiwan, India, France, Australia and New Zealand.
Inmarsat is a British satellite telecommunications company, offering global mobile services. It provides telephone and data services to users worldwide, via portable or mobile terminals which communicate with ground stations through fifteen geostationary telecommunications satellites.
Vessel Monitoring Systems (VMS) is a general term to describe systems that are used in commercial fishing to allow environmental and fisheries regulatory organizations to track and monitor the activities of fishing vessels. They are a key part of monitoring control and surveillance (MCS) programs at national and international levels. VMS may be used to monitor vessels in the territorial waters of a country or a subdivision of a country, or in the Exclusive Economic Zones (EEZ) that extend 200 nautical miles (370.4 km) from the coasts of many countries. VMS systems are used to improve the management and sustainability of the marine environment, through ensuring proper fishing practices and the prevention of illegal fishing, and thus protect and enhance the livelihoods of fishermen.
SES Broadband is a two-way satellite broadband Internet service available across Europe, which launched in March 2007, and uses the Astra series of geostationary satellites.
Quake Global is a technology company that provides products for asset tracking, location, and analytics. Quake Global designs and implements facility or campus level asset tracking products typically based around RFID and/ or BLE technology. In 2012, Quake Global received an Inc. 5000 rank of 82 in the San Diego Metro Area. The company is based in San Diego.
Inmarsat-3 F4 is a communications satellite operated by the British satellite operator Inmarsat. It was launched into a geosynchronous orbit on 4 June 1997. It was located at 54° West longitude whilst in service, providing coverage of the Americas as Atlantic Ocean Region-West (AOR-W). It was replaced by Inmarsat-3 F5 at 54° West in February 2016, and the now retired Inmarsat-3 F4 was moved to parking at 144° West.
Mobile-satellite service is – according to Article 1.25 of the International Telecommunication Union's Radio Regulations – "A radiocommunication service
Globalsat Group is a consortium of companies providing satellite communication services worldwide with headquarters located in the United States.
