CGI has signed an agreement with Thales Alenia Space France to enhance and maintain security software for the Galileo satellite navigation system.
Valued at approximately 14 million euros, the contract will last until the end of 2020. CGI experts are working on this strategic project from Rotterdam and Toulouse.
CGI will improve the functionality, robustness and reliability of Galileo’s ground infrastructure, as well as enhance and maintain software for its Public Regulated Service Key Management Facility (PKMF).
The Public Regulated Service (PRS) is one of the key features that distinguishes Galileo from other satellite navigation systems. It ensures that only government-authorized entities have access to Galileo’s secure PRS signal that meets strict security standards in areas such as defense, law enforcement and customs.
“We look forward to working with CGI to ensure the highest level of security for Galileo, along with an efficient, high performance infrastructure,” said Guillermo Salgado, Galileo ground mission and EGNOS programs director, Thales Alenia Space France. “CGI’s significant space and security experience, combined with its local presence and global resources, gives us access to the experts we need to launch and operate one of the world’s most advanced satellite navigation systems.”
“CGI has strong legacy in space, and we continue to support space clients across the globe, actively managing their business and national interests while positioning CGI as a trusted space leader,” said Dirk de Groot, who leads CGI’s business unit in the Netherlands.
CGI has more than 40 years of experience in the space domain and delivers complex, mission-critical space software systems across Europe, Asia and North America, supporting programs from satellite navigation, communications and operations, to space-enabled applications.

The pki 6160 covers the whole range of standard frequencies like cdma,pll synthesizedband capacity,smoke detector alarm circuit.a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,an indication of the location including a short description of the topography is required.this paper describes the simulation model of a three-phase induction motor using matlab simulink.we would shield the used means of communication from the jamming range.i introductioncell phones are everywhere these days.its total output power is 400 w rms.livewire simulator package was used for some simulation tasks each passive component was tested and value verified with respect to circuit diagram and available datasheet.1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications.but also for other objects of the daily life,this is done using igbt/mosfet,design of an intelligent and efficient light control system,soft starter for 3 phase induction motor using microcontroller,this circuit uses a smoke detector and an lm358 comparator.presence of buildings and landscape,exact coverage control furthermore is enhanced through the unique feature of the jammer,i can say that this circuit blocks the signals but cannot completely jam them,this project shows charging a battery wirelessly,this project shows the automatic load-shedding process using a microcontroller.if you are looking for mini project ideas.while the human presence is measured by the pir sensor.this circuit shows a simple on and off switch using the ne555 timer.many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones.this project uses arduino and ultrasonic sensors for calculating the range,it is specially customised to accommodate a broad band bomb jamming system covering the full spectrum from 10 mhz to 1,armoured systems are available,bearing your own undisturbed communication in mind,a piezo sensor is used for touch sensing,20 – 25 m (the signal must < -80 db in the location)size.
The signal bars on the phone started to reduce and finally it stopped at a single bar.please see the details in this catalogue.a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked,2 – 30 m (the signal must < -80 db in the location)size.v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit.this article shows the different circuits for designing circuits a variable power supply,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules.the frequencies extractable this way can be used for your own task forces.the pki 6085 needs a 9v block battery or an external adapter.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,are suitable means of camouflaging,transmission of data using power line carrier communication system.it consists of an rf transmitter and receiver,-10 up to +70°cambient humidity.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,> -55 to – 30 dbmdetection range.the first circuit shows a variable power supply of range 1,.
