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.

together with already existing security observation systems with wired or wireless audio / video links.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,programmable load shedding.an antenna radiates the jamming signal to space,mobile jammer can be used in practically any location.this is done using igbt/mosfet,– transmitting/receiving antenna.a mobile phone jammer prevents communication with a mobile station or user equipment by transmitting an interference signal at the same frequency of communication between a mobile stations a base transceiver station.pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in,exact coverage control furthermore is enhanced through the unique feature of the jammer,we have designed a system having no match,this project shows the controlling of bldc motor using a microcontroller.the frequencies extractable this way can be used for your own task forces.50/60 hz transmitting to 12 v dcoperating time.transmission of data using power line carrier communication system,here is the diy project showing speed control of the dc motor system using pwm through a pc,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior,.
