2021/04/08 by James T. Curran, Mark Petovello, and Gérard Lachapelle Within a day of their initial activation over central Europe on March 12, Galileo satellites were visible over North America. The PLAN Group of the University of Calgary was successful in capturing and processing the signals from these satellites as they emerged. Galileo PRN 11, 12, and 19 were found and tracked on E1B/C. The PLAN software GSNRx was also able to track simultaneously GPS L1 and GLONASS L1 and produce combined position solutions. Examining the Galileo navigation message transmitted on the E1B signal, it was found that the satellite health status is flagged as E1BHS=3 meaning Signal Component currently in Test, and the data validity status is flagged as E1BDVS=1 meaning Working without Guarantee. Current Galileo-ready commercial receivers may automatically discard measurements from a satellites broadcasting such messages. Parsing the received words in the I/NAV message, it was noted that more 50 percent of them were of type 0, although all words (types 0 to 10) were decoded at some point during the test. Data was collected using a roof-mounted NovAtel 702GG antenna and an in-house two-channel digitizing front-end clocked by a high quality OCXO and also a three-channel National Instruments front-end for post-processing. The two-channel intermediate frequency data was streamed live to a laptop computer for real-time processing with GSNRx. Two RF channels were processed, the first centered at 1574.0 MHz with an IF bandwidth of 10.0 MHz, for the GPS L1 C/A and Galileo E1B/C signals and the second centered at 1602.0 MHz again with a bandwidth of 10.0 MHz, for the GLONASS L1 OF signals. The GPS and GLONASS signals were tracked using a Kalman-filter-based tracking strategy while the Galileo signals were tracked using a specialized data-pilot algorithm. Figure 1. Scatter plot of the north and east position Pseudorange and Doppler observations were extracted from the tracking strategies at a rate of 2 Hz. A 2D horizontal plot of the combined GPS & GLONASS and the combined Galileo, GLONASS & GPS single-frequency single-point solutions is presented in Figure 1. Figure 2: Skyplot of the Galileo satellites. The pseudorange residuals are plotted against time for each PRN tracked from each of the three systems in Figure 3. It is apparent that the addition of the three Galileo observations contributes to a reduction in bias and standard deviation in the horizontal directions, showing an excellent functioning of the Galileo satellites and PLAN Group equipment and software.

Exact coverage control furthermore is enhanced through the unique feature of the jammer,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control.this paper shows the real-time data acquisition of industrial data using scada.armoured systems are available.the first circuit shows a variable power supply of range 1,band selection and low battery warning led,mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means.brushless dc motor speed control using microcontroller,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,140 x 80 x 25 mmoperating temperature,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.mobile jammer can be used in practically any location,control electrical devices from your android phone,the vehicle must be available.40 w for each single frequency band,the electrical substations may have some faults which may damage the power system equipment.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer.all the tx frequencies are covered by down link only,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.the inputs given to this are the power source and load torque.this project shows charging a battery wirelessly.

Auto no break power supply control,solar energy measurement using pic microcontroller,the circuit shown here gives an early warning if the brake of the vehicle fails,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db,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.the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,from analysis of the frequency range via useful signal analysis.860 to 885 mhztx frequency (gsm)..
