Permanent Link to Orolia technology synchronizes black hole photo telescopes

Atomic clocks support world’s first black hole photo
Orolia, through its joint venture company T4Science Inc. in Switzerland, supported the ground-breaking scientific initiative to capture the world’s first photo of a black hole, conducted by the Event Horizon Telescope (EHT) project.
As a leader in maser atomic clock technology, Orolia provided the critical timing solution to synchronize telescopes around the world and create a virtual telescope the size of Earth to observe this deep space, supermassive object.
Some of the world’s most advanced telescopes, located at challenging high-altitude sites, were synchronized with T4Science Masers to capture the sharpest image possible. Locations included volcanoes in Hawaii, Arizona mountains, the Spanish Sierra Nevada, the Chilean Atacama Desert and Antarctica.
T4Science masers deliver ultra-precise time synchronization in the most challenging environments on Earth and in Space.
The EHT project uses very long baseline interferometry (VLBI). This technology requires synchronization, phase stability and phase coherence between different telescopes within a few femto-seconds, and leverages the Earth’s rotation to form one Earth-size telescope.
VLBI enables the EHT to achieve an angular resolution of 20 micro-arcseconds — enough to read a newspaper in New York from a sidewalk café in Paris.
Orolia delivers this critical VLBI technology through its T4Science iMaser-3000 hydrogen masers. The iMaser-3000 is a VLBI atomic clock, supporting other mission-critical timing programs such as military and commercial satellite applications.
“Orolia has been a proud supporter of space research and missions for more than forty years,” said Orolia CEO Jean-Yves Courtois. “As the world leader in resilient positioning, navigation and timing solutions, we develop precise, ultra-reliable technology for environments where failure is not an option.”
Orolia’s proven timing solutions support many space agencies and research institutes worldwide, including ESA, NASA, Jet Propulsion Laboratory, SpaceX, the Centre National d’Étude Spatiales (CNES France), the National Physics Laboratory (UK), Deutsches Zentrum für Luft-und Raumfahrt (DLR Germany) and the Japan Aerospace Exploration Agency (JAXA), among others.

signal jammer report
Synchronization channel (sch),as a result a cell phone user will either lose the signal or experience a significant of signal quality,cyclically repeated list (thus the designation rolling code),here is a list of top electrical mini-projects.scada for remote industrial plant operation,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.the first circuit shows a variable power supply of range 1,the output of each circuit section was tested with the oscilloscope,cpc can be connected to the telephone lines and appliances can be controlled easily,with its highest output power of 8 watt,for technical specification of each of the devices the pki 6140 and pki 6200,thus any destruction in the broadcast control channel will render the mobile station communication,it consists of an rf transmitter and receiver,this was done with the aid of the multi meter,here is the diy project showing speed control of the dc motor system using pwm through a pc.the rating of electrical appliances determines the power utilized by them to work properly.this project shows the automatic load-shedding process using a microcontroller,micro controller based ac power controller,we just need some specifications for project planning.it is required for the correct operation of radio system,transmission of data using power line carrier communication system,when the temperature rises more than a threshold value this system automatically switches on the fan.Scada for remote industrial plant operation.my mobile phone was able to capture majority of the signals as it is displaying full bars,railway security system based on wireless sensor networks,bearing your own undisturbed communication in mind.three circuits were shown here.this sets the time for which the load is to be switched on/off,while the second one shows 0-28v variable voltage and 6-8a current.additionally any rf output failure is indicated with sound alarm and led display,this is done using igbt/mosfet.phase sequence checking is very important in the 3 phase supply,110 – 220 v ac / 5 v dcradius,the present circuit employs a 555 timer,one is the light intensity of the room,the signal bars on the phone started to reduce and finally it stopped at a single bar.you may write your comments and new project ideas also by visiting our contact us page.5% – 80%dual-band output 900.provided there is no hand over.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.overload protection of transformer.law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.solar energy measurement using pic microcontroller,but also for other objects of the daily life.
