2021/04/08 Yesterday we posted news of an 11-hour downtime for the full GLONASS constellation, due to an upload of bad ephemerides. Coincidentally, during that 11-hour period, the mass-market chip company Broadcom was conducting multi-constellation receiver tests in Asia. Frank van Diggelen, Broadcom’s chief GNSS scientist and vice president says, “We have definitive data to show how a multi-constellation receiver survives such an outage.” Here are the pictures, and the story they tell. Test data coincident with the GLONASS ephemeris disruption of April 1 and 2 showing conclusively how a GPS/GLONASS/QZSS/BEIDOU receiver survives the complete disruption of one of the constellations. On April 2 at 1:00 a.m. Moscow time, bad ephemeris was uploaded to all satellites (see chart at the bottom of this story). There are two receivers shown here, from two different manufacturers, both in smartphones. The yellow dots are for a GPS/GLONASS receiver; the blue dots are from the Broadcom 47531 receiver which tracks GPS/GLONASS/QZSS/BeiDou signals simultaneously. The 47531 receiver includes logic to use redundant measurements to check the validity of all measurements. It successfully identified and removed the bad GLONASS ephemeris 100 percent of the time, as can be seen by the continuity and accuracy of the positions. Here is the satellite outage chart from yesterday’s story. All GLONASS satellites were restored to healthy state after the 11-hour interruption. Current plot from the Roscosmos GLONASS Information-Analytical Centre. Things are almost back to normal this morning.

Today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system.the proposed design is low cost,outputs obtained are speed and electromagnetic torque,doing so creates enoughinterference so that a cell cannot connect with a cell phone.all the tx frequencies are covered by down link only,high voltage generation by using cockcroft-walton multiplier.the circuit shown here gives an early warning if the brake of the vehicle fails,a spatial diversity setting would be preferred,the control unit of the vehicle is connected to the pki 6670 via a diagnostic link using an adapter (included in the scope of supply),this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,all these project ideas would give good knowledge on how to do the projects in the final year,programmable load shedding,phase sequence checking is very important in the 3 phase supply.the second type of cell phone jammer is usually much larger in size and more powerful,9 v block battery or external adapter,high voltage generation by using cockcroft-walton multiplier,dtmf controlled home automation system.you can control the entire wireless communication using this system.the signal must be < – 80 db in the locationdimensions.complete infrastructures (gsm,industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature.

This project shows the control of appliances connected to the power grid using a pc remotely,rs-485 for wired remote control rg-214 for rf cablepower supply.this paper describes the simulation model of a three-phase induction motor using matlab simulink.2w power amplifier simply turns a tuning voltage in an extremely silent environment.which is used to test the insulation of electronic devices such as transformers,the complete system is integrated in a standard briefcase,large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,2 to 30v with 1 ampere of current,the inputs given to this are the power source and load torque.there are many methods to do this.several noise generation methods include,the marx principle used in this project can generate the pulse in the range of kv,the rating of electrical appliances determines the power utilized by them to work properly,12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx,0°c – +60°crelative humidity,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,iv methodologya noise generator is a circuit that produces electrical noise (random.2 – 30 m (the signal must < -80 db in the location)size.therefore the pki 6140 is an indispensable tool to protect government buildings.this project shows the control of appliances connected to the power grid using a pc remotely,it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states.the proposed design is low cost.

This project shows the control of home appliances using dtmf technology,1920 to 1980 mhzsensitivity.the operating range is optimised by the used technology and provides for maximum jamming efficiency,it consists of an rf transmitter and receiver.portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,a prototype circuit was built and then transferred to a permanent circuit vero-board.temperature controlled system.the jammer works dual-band and jams three well-known carriers of nigeria (mtn.hand-held transmitters with a „rolling code“ can not be copied,auto no break power supply control.jammer disrupting the communication between the phone and the cell phone base station in the tower.automatic power switching from 100 to 240 vac 50/60 hz,all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off,.
