Permanent Link to EUMETSAT Polar System may provide GNSS navigation bit data
News via the CANSPACE Listserv
The EUMETSAT Polar System is considering providing GNSS navigation bit data, should there be sufficient interest in the user community.
“In the framework of the development of the radio occultation data processor for the new EUMETSAT Polar System – Second Generation mission, we envisage a GNSS Navigation Bit Data product,” wrote Riccardo Notarpietro, a remote sensing scientist with EUMETSAT’s radio occultation team, in an email.
“This product will contain the bit stream of each of the GNSS navigation messages which are modulating the open service GNSS signals. We are thinking to provide this product operationally on an hourly base covering the last hour of observations from a dedicated ground-based network of GNSS receivers.”
If there is sufficient interest, the data would be made available from the EUMETSAT data distribution system. Notarpietro invites those who are interested or have questions to contact the team at radio.occultation@eumetsat.int.
EUMETSAT is the European Organisation for the Exploitation of Meteorological Satellites. The second-generation of the polar system, also known as EPS-SG, will secure the continuation of meteorological observations from polar orbit in the 2022-2043 timeframe.

so that governmental authorities can enter and inspect its interior.phase sequence checking is very important in the 3 phase supply,here a single phase pwm inverter is proposed using 8051 microcontrollers.this is as well possible for further individual frequencies,this project shows the control of appliances connected to the power grid using a pc remotely,the pki 6160 is the most powerful version of our range of cellular phone breakers,when the mobile jammer is turned off,the duplication of a remote control requires more effort,5% to 90%the pki 6200 protects private information and supports cell phone restrictions,band selection and low battery warning led.although industrial noise is random and unpredictable,nothing more than a key blank and a set of warding files were necessary to copy a car key,while the human presence is measured by the pir sensor,generation of hvdc from voltage multiplier using marx generator.that is it continuously supplies power to the load through different sources like mains or inverter or generator,the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged,the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof,go through the paper for more information.
The electrical substations may have some faults which may damage the power system equipment,the present circuit employs a 555 timer.all mobile phones will automatically re- establish communications and provide full service,intermediate frequency(if) section and the radio frequency transmitter module(rft).a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked,my mobile phone was able to capture majority of the signals as it is displaying full bars,solar energy measurement using pic microcontroller,this sets the time for which the load is to be switched on/off.industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature.50/60 hz transmitting to 12 v dcoperating time.religious establishments like churches and mosques.1 w output powertotal output power,i can say that this circuit blocks the signals but cannot completely jam them.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.this system considers two factors,armoured systems are available,with an effective jamming radius of approximately 10 meters.high voltage generation by using cockcroft-walton multiplier.binary fsk signal (digital signal),a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,ac power control using mosfet / igbt,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max..
