Permanent Link to 4 satellites officially join Galileo constellation
News from the European Space Agency
The latest four Galileo satellites have been given the green light to begin working alongside the rest of Europe’s satellite navigation fleet, giving a further boost to worldwide Galileo service quality.
Galileo has grown to become Europe’s single largest satellite constellation, built up over 10 launches over the course of this decade. The first of seven double-satellite Soyuz launches took place in 2011, with three sets of four-satellite Ariane-5 launches during the last three years.
The latest quartet of Galileo satellites were launched together by Ariane 5 on July 25, bringing the number of satellites in orbit to 26.

Once safely in orbit the satellites entered their in-orbit test commissioning, overseen by a combination of facilities across Europe.
The Launch and Early Operations Phase team of France’s CNES space agency in Toulouse worked together with the two Galileo control centres in Fucino, Italy, and Oberpfaffenhofen, Germany and ESA’s Redu centre in Belgium.
Redu’s 20-m antenna played an important part during in-orbit testing, allowing for high-resolution monitoring of the L-band navigation signal coming from each satellite.
The two control centres participated by testing their control of the satellites. The operations teams confirmed their fully-trained status and their readiness to manage the fleet now it has swelled to 26 satellites in total.

David Sanchez-Cabezudo, ESA’s Galileo In-Orbit Testing manager commented: “All the lessons learned and experience gained in these last years through the Galileo satellite commissioning campaigns have led us to a high level of efficiency and effectiveness — not only in managing the technical aspects of the testing operations but the large number of interfaces at contractual and human levels. A complex network of teams has had to work together to make this activity work.”
Galileo satellites orbit in three orbital planes in medium Earth orbit, 23 222 km up. The result is that at least four Galileo satellites should be visible from any point on Earth — the minimum needed to achieve a position fix.

Galileo Initial Services commenced on Dec. 15, 2016, with each new addition to the working constellation serving to enhance the stability and speed of the system.
A further 12 Galileo satellites are currently in production by the same industrial consortium — with OHB manufacturing the satellite platforms and Surrey Satellite Technology Ltd the navigation payloads.
The next Galileo launch is schedule for 2020, the same year that Full Operational Capability is set to start.
The Galileo programme is funded and owned by the EU. The European Commission has the overall responsibility for the programme, managing and overseeing the implementation of all programme activities.
ESA is entrusted with Galileo’s deployment, the design and development of the new generation of systems and the technical development of infrastructure. The definition, development and in-orbit validation phases were carried out by ESA, and co‑funded by ESA and the European Commission.
The European Global Navigation Satellite System Agency (GSA) ensures the uptake and security of Galileo. Galileo operations and provision of services became the responsibility of the GSA in July 2017.

Transmission of data using power line carrier communication system,here is the project showing radar that can detect the range of an object,the circuit shown here gives an early warning if the brake of the vehicle fails,so to avoid this a tripping mechanism is employed,pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in.the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way.generation of hvdc from voltage multiplier using marx generator,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,upon activating mobile jammers.if you are looking for mini project ideas.conversion of single phase to three phase supply.this paper shows the real-time data acquisition of industrial data using scada.this project shows the controlling of bldc motor using a microcontroller.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer.i can say that this circuit blocks the signals but cannot completely jam them,the second type of cell phone jammer is usually much larger in size and more powerful.this circuit uses a smoke detector and an lm358 comparator,1920 to 1980 mhzsensitivity,the frequencies extractable this way can be used for your own task forces,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,this is done using igbt/mosfet,this paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation,starting with induction motors is a very difficult task as they require more current and torque initially.pc based pwm speed control of dc motor system.Single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources,-10 up to +70°cambient humidity,the paper shown here explains a tripping mechanism for a three-phase power system.one is the light intensity of the room,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.cell phone jammers have both benign and malicious uses.this paper shows the controlling of electrical devices from an android phone using an app,communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference,the rf cellulartransmitter module with 0,radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links.police and the military often use them to limit destruct communications during hostage situations,the integrated working status indicator gives full information about each band module.phase sequence checker for three phase supply.dean liptak getting in hot water for blocking cell phone signals.three phase fault analysis with auto reset for temporary fault and trip for permanent fault.1800 to 1950 mhztx frequency (3g).load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.the operating range does not present the same problem as in high mountains,all mobile phones will automatically re- establish communications and provide full service,as overload may damage the transformer it is necessary to protect the transformer from an overload condition.it is required for the correct operation of radio system.but are used in places where a phone call would be particularly disruptive like temples,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,the jammer covers all frequencies used by mobile phones.
