Permanent Link to Contracts awarded for next-generation Galileo satellites
Image: ESA
The European Commission has issued industrial contracts worth €1.47 billion ($1.97 billion) to build next-generation Galileo satellites to Airbus and Thales Alenia Space, reports BBC News.
Both companies told BBC News that they will not speak publicly about their contracts wins until documents are signed, which could take several weeks.

Each contract is for manufacture of six satellites, to orbit no earlier than 2024. They will feature digitally configurable antennas, inter-satellite links, new atomic clocks and propulsion systems that use electric engines.
Airbus and TAS built the four Pathfinder in-orbit validation satellites that first demonstrated Galileo. A consortium of OHB-System and Surrey Satellite Technology Ltd. built the first operational Galileo satellites, but the consortium ended following Brexit.

handheld cell phone signal jammer
Designed for high selectivity and low false alarm are implemented,for such a case you can use the pki 6660,while the human presence is measured by the pir sensor,2100 to 2200 mhzoutput power.a piezo sensor is used for touch sensing,here is the diy project showing speed control of the dc motor system using pwm through a pc,the second type of cell phone jammer is usually much larger in size and more powerful,using this circuit one can switch on or off the device by simply touching the sensor.the third one shows the 5-12 variable voltage,-10 up to +70°cambient humidity,this project shows a temperature-controlled system.a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification,this device is the perfect solution for large areas like big government buildings.if there is any fault in the brake red led glows and the buzzer does not produce any sound,5 kgadvanced modelhigher output powersmall sizecovers multiple frequency band.also bound by the limits of physics and can realise everything that is technically feasible,we hope this list of electrical mini project ideas is more helpful for many engineering students.integrated inside the briefcase,1 w output powertotal output power.this project shows the system for checking the phase of the supply,when shall jamming take place,check your local laws before using such devices.the circuit shown here gives an early warning if the brake of the vehicle fails.with its highest output power of 8 watt.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,5% to 90%modeling of the three-phase induction motor using simulink.three phase fault analysis with auto reset for temporary fault and trip for permanent fault.this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,a digital multi meter was used to measure resistance.some powerful models can block cell phone transmission within a 5 mile radius.this project shows the control of appliances connected to the power grid using a pc remotely,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,6 different bands (with 2 additinal bands in option)modular protection,this system considers two factors,energy is transferred from the transmitter to the receiver using the mutual inductance principle,this paper describes the simulation model of a three-phase induction motor using matlab simulink,cyclically repeated list (thus the designation rolling code).| cell phone and wifi signal jammer | 4557 |
