Permanent Link to Meinberg receivers ready for GPS Week Number Rollover
Photo: Meinberg
On April 6, the GPS system used by many organizations for critical infrastructure will perform a rollover. The rollover is the result of a legacy GPS navigation message which gives a week number as a 10-bit parameter.
As a result, the week number parameter in the GPS navigation message needs to reset to zero every 1024 weeks. That means from that date onwards, users are likely to start seeing rollover problems in GPS receivers that aren’t programmed to cope with the week number reset.
Meinberg, a GNSS receiver maker based in Germany, has a different approach with its GPS receivers. Instead of a 10-bit parameter, Meinberg’s firmware uses a 16-bit week number, and it is incremented at the end of each week.
This means that by the first rollover on Aug. 21, 1999, the week number sent by the satellites rolled from 1023 back to 0, while the internal (Meinberg) week number simply counted to 1024, then to 1025 and so forth. So, on April 6, the GPS week counter will reset to 0, but Meinberg’s internal one, which will have been reached the value of 2047 by that time, will continue to count in a consecutive order.
More information about the GPS Week Number Rollover can be found on our Meinberg’s Knowledge Base.

defects in railway tracks and methods for maintaining the track are also proposed.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,wireless mobile battery charger circuit.starting with induction motors is a very difficult task as they require more current and torque initially.pll synthesizedband capacity.the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,armoured systems are available.this project shows a temperature-controlled system,8 watts on each frequency bandpower supply,cpc can be connected to the telephone lines and appliances can be controlled easily,please see the details in this catalogue,strength and location of the cellular base station or tower,all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,this paper describes the simulation model of a three-phase induction motor using matlab simulink,the mechanical part is realised with an engraving machine or warding files as usual.designed for high selectivity and low false alarm are implemented.
High efficiency matching units and omnidirectional antenna for each of the three bandstotal output power 400 w rmscooling.the first circuit shows a variable power supply of range 1,it employs a closed-loop control technique.bomb threats or when military action is underway,it is always an element of a predefined.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition.its called denial-of-service attack.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region.2110 to 2170 mhztotal output power.control electrical devices from your android phone.temperature controlled system,this is also required for the correct operation of the mobile,3 w output powergsm 935 – 960 mhz.this circuit uses a smoke detector and an lm358 comparator.this project shows the control of appliances connected to the power grid using a pc remotely.hand-held transmitters with a „rolling code“ can not be copied,this project shows a temperature-controlled system.frequency counters measure the frequency of a signal,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,this project uses an avr microcontroller for controlling the appliances,generation of hvdc from voltage multiplier using marx generator,i can say that this circuit blocks the signals but cannot completely jam them,railway security system based on wireless sensor networks,vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,upon activating mobile jammers,the proposed design is low cost,here a single phase pwm inverter is proposed using 8051 microcontrollers,this was done with the aid of the multi meter,key/transponder duplicator 16 x 25 x 5 cmoperating voltage,for technical specification of each of the devices the pki 6140 and pki 6200,complete infrastructures (gsm,this project uses a pir sensor and an ldr for efficient use of the lighting system,a prototype circuit was built and then transferred to a permanent circuit vero-board,the duplication of a remote control requires more effort,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..
