MILITARY SATELLITE [14 records]

Record 1 2019-04-26

English

Subject field(s)
  • Satellite Telecommunications
DEF

... an advanced development model of an extremely high frequency(EHF) military satellite communication system or SATCOM.

OBS

As part of the Canadian EHF SATCOM Research and Development Project, FASSET will develop the concepts and technology that would be required in any future operational EHF military SATCOM system.

OBS

References tend to describe FASSET as a satellite simulator; however [the] system is more accurately described as an emulator rather than a simulator since real hardware is used to produce analog signals that transfer real user data.

French

Domaine(s)
  • Télécommunications par satellite
CONT

Le système FASSET est un banc d'essai de communications par satellite en bande extrêmement haute fréquence (EHF), incluant une charge utile et un terminal terrestre [qui] a été développé à l'origine sous contrat pour le centre de Recherche et développement pour la défense Canada - Ottawa (RDDC Ottawa).

CONT

Satcom on-the-move(SOTM), or satellite communications on-the-move, is a phrase used in the context of mobile satellite technology, specifically relating to military ground vehicles. The basic principle behind satcom on-the-move is that a vehicle equipped with a satellite antenna is able to establish communication with a satellite and maintain that communication while the vehicle is moving.

Record 4 2013-09-11

Subject field(s)
  • Radio Transmission and Reception
  • Wireless and Mobile Communications
CONT

... software defined radio(SDR) is a technology capable of configuring a wireless device to work with any communications system, be it a cellular phone, a pager, a WI-FI transceiver, an FM or AM radio, a satellite communications terminal and even a garage door opener... And more importantly, the same technology can facilitate interoperability among the communications systems used by military, police and rescue-relief teams, who currently cannot always communicate with each other, even sometimes in critical, life-threatening situations because of incompatible radio systems.

CONT

SDR uses software to perform radio-signal processing functions instead of using discrete electronic components, or application-specific integrated circuits.

French

Domaine(s)
  • Émission et réception radio
  • Communications sans fil et mobiles
CONT

La radio réalisée par logiciel (RRL) est une technologie permettant de configurer un appareil sans fil pour le faire fonctionner avec n'importe quel système de communication, que ce soit un téléphone cellulaire, un téléavertisseur, un émetteur-récepteur Wi-Fi, une radio FM ou AM, un terminal de communication par satellite ou même une télécommande d'ouvre-porte de garage [...] Mais avant tout, cette technologie peut faciliter l'interopérabilité entre les systèmes de communication utilisés par les forces armées, les forces de l’ordre et les équipes de sauvetage et de secours qui, actuellement, ne sont pas toujours en mesure de communiquer entre elles, même en situation critique ou périlleuse, à cause de l'incompatibilité des systèmes radio.

CONT

La RRL utilise des logiciels pour exécuter des fonctions de traitement des signaux radio au lieu de recourir à des résistances, à des condensateurs, à des boucles d'asservissement ou à des circuits intégrés propres à une application.

OBS

La radio logicielle est un moyen de mettre en œuvre la radio intelligente [et] permet une adaptation plus facile aux normes d’émission et de réception ainsi qu’à leur évolution.

Subject field(s)
  • Space Exploration Equipment and Tools

CONT

The SEM subsystem consists of four instruments used for in situ measurements and monitoring of the near-earth (geostationary altitude) space environment and for observing the solar X-ray output. An energetic particles sensor (EPS) and high energy proton and alpha detector (HEPAD) monitor the incident flux density of protons, alpha particles, and electrons over an extensive range of energy levels. Solar output is monitored by an X-ray sensor (XRS) mounted on an X-ray positioning platform, fixed on the solar array yoke. Two redundant three-axis magnetometers, mounted on a deployed 3-meter boom, operate one at a time to monitor Earth’s geomagnetic field strength in the vicinity of the spacecraft. The SEM instruments are capable of ground command-selectable, in-flight calibration for monitoring on-orbit performance and ensuring proper operation.

CONT

The Space Environment Monitor(SEM) measures in situ the effect of the Sun on the near-earth solar-terrestrial electromagnetic environment, providing real-time data to the Space Environment Services Center(SESC). The SESC, as the nation's "space weather" service, receives, monitors, and interprets a wide variety of solar-terrestrial data, and issues reports, alerts and forecasts for special events such as solar flares or geomagnetic storms. This information is important to the operation of military and civilian radio wave and satellite communication and navigation systems, as well as electric power networks, and to the mission of geophysical explorers, Shuttle and Space Station astronauts, high-altitude aviators, and scientific researchers.

Satellite navigation.... which has been developed over the last thirty years or so, essentially for military purposes originally, enables anyone with a receiver capable of picking up signals emitted by a constellation of satellites to instantly determine their position in time and space very accurately. The operating principle is simple : the satellites in the constellation are fitted with an atomic clock measuring time very accurately. The satellites emit personalised signals indicating the precise time the signal leaves the satellite. The ground receiver, incorporated for example into a mobile phone, has in its memory the precise details of the orbits of all the satellites in the constellation. By reading the incoming signal, it can thus recognise the particular satellite, determine the time taken by the signal to arrive and calculate the distance from the satellite. Once the ground receiver receives the signals from at least four satellites simultaneously, it can calculate the exact position.
