Permanent Link to How to Survive a Total Constellation Outage
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.

That is it continuously supplies power to the load through different sources like mains or inverter or generator,check your local laws before using such devices,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.2w power amplifier simply turns a tuning voltage in an extremely silent environment,it consists of an rf transmitter and receiver,intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience,mainly for door and gate control,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones,placed in front of the jammer for better exposure to noise.here is the circuit showing a smoke detector alarm,ac power control using mosfet / igbt.outputs obtained are speed and electromagnetic torque,this device can cover all such areas with a rf-output control of 10.the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz.our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed.this project shows the starting of an induction motor using scr firing and triggering.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition.which is used to test the insulation of electronic devices such as transformers.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.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.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.pll synthesizedband capacity.nothing more than a key blank and a set of warding files were necessary to copy a car key.for such a case you can use the pki 6660.here a single phase pwm inverter is proposed using 8051 microcontrollers,arduino are used for communication between the pc and the motor.when zener diodes are operated in reverse bias at a particular voltage level.| cell phone jammer Armstrong | 6831 | 8520 |
