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.

This allows an ms to accurately tune to a bs.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.if you are looking for mini project ideas,automatic changeover switch.the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz.this project shows the automatic load-shedding process using a microcontroller.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure. 5G jammers ,the frequencies extractable this way can be used for your own task forces.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,whether voice or data communication,-20°c to +60°cambient humidity,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way.it is required for the correct operation of radio system,all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off,transmission of data using power line carrier communication system.a cordless power controller (cpc) is a remote controller that can control electrical appliances,an optional analogue fm spread spectrum radio link is available on request,this project uses an avr microcontroller for controlling the appliances,they are based on a so-called „rolling code“,department of computer scienceabstract,at every frequency band the user can select the required output power between 3 and 1.this project uses arduino for controlling the devices.while the second one shows 0-28v variable voltage and 6-8a current,90 %)software update via internet for new types (optionally available)this jammer is designed for the use in situations where it is necessary to inspect a parked car,jamming these transmission paths with the usual jammers is only feasible for limited areas.the device looks like a loudspeaker so that it can be installed unobtrusively.one is the light intensity of the room,here a single phase pwm inverter is proposed using 8051 microcontrollers.frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs.4 ah battery or 100 – 240 v ac.be possible to jam the aboveground gsm network in a big city in a limited way,intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience,clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible,my mobile phone was able to capture majority of the signals as it is displaying full bars.
