2021/04/09 During preparation of playback scenarios for the upcoming leap-second event taking place in June, engineers at Racelogic identified a potential pitfall for GNSS engineers. The difficulty arises from the fact that BeiDou uses a different “day number” for the date to apply the leap second, compared with GPS and Galileo. GPS and Galileo use 1-7 as week day numbers, and BeiDou uses 0-6. If this fact has been missed during development, then the result is that the leap second may be implemented a day early on GNSS engines that are tracking the BeiDou constellation, said Mark Sampson, product manager for Racelogic. “We tested four different Beidou enabled receivers, from four leading GNSS companies, and none of them appeared to handle the Beidou leap second correctly. This included an engine which originates from China!” Sampson said. “We have since been in contact with two of these companies, who have confirmed that their hardware does have a bug in the leap-second code due to the numbering of the days.” The error presents itself when the receiver is running on the BeiDou constellation alone, and when the date is June 29 of this year. In some cases, the BeiDou leap second will be adjusted from 2 to 3 seconds from midnight on June 29, which should in fact occur on midnight of June 30. This will result in an error for the reported UTC time of 1 second for the period of this day. In other cases, the leap second was not implemented at all when running on BeiDou alone. “We have also checked the output of a BeiDou signal generator from a different simulator company, and this too uses the 1-7 range for the BeiDou leap-second date instead of the correct 0-6 range,” Sampson said. “This may explain why a number of commercial receivers appear to have been caught out by this issue.” Racelogic LabSat3 simulator. In order to help companies test for this problem, Racelogic has generated simulated RF data for June 29 and 30, starting 15 minutes before midnight. “We have two sets of files. One set contains BeiDou only signals and the other contains a combination of BeiDou and GPS signals,” Sampson said. “Note that on some of the receivers we have tested, when GPS is being tracked as well, the GPS leap-second message overrides the one coming from BeiDou and applies the leap second correctly.” The scenarios are compatible with Racelogic’s LabSat3 triple constellation simulator, which is available on a free 15-day loan or can be purchased from Racelogic.

A digital multi meter was used to measure resistance,this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies,4 ah battery or 100 – 240 v ac.1800 to 1950 mhztx frequency (3g).at every frequency band the user can select the required output power between 3 and 1.this is done using igbt/mosfet.one of the important sub-channel on the bcch channel includes,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,1800 to 1950 mhz on dcs/phs bands,three circuits were shown here,incoming calls are blocked as if the mobile phone were off,the rating of electrical appliances determines the power utilized by them to work properly,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,phase sequence checking is very important in the 3 phase supply,this was done with the aid of the multi meter.as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,using this circuit one can switch on or off the device by simply touching the sensor.they go into avalanche made which results into random current flow and hence a noisy signal,you can copy the frequency of the hand-held transmitter and thus gain access,2 to 30v with 1 ampere of current,when the temperature rises more than a threshold value this system automatically switches on the fan,3 w output powergsm 935 – 960 mhz.

Mobile jammers effect can vary widely based on factors such as proximity to towers,cpc can be connected to the telephone lines and appliances can be controlled easily.we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,can be adjusted by a dip-switch to low power mode of 0,the inputs given to this are the power source and load torque,110 to 240 vac / 5 amppower consumption,ac power control using mosfet / igbt,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,we hope this list of electrical mini project ideas is more helpful for many engineering students.with an effective jamming radius of approximately 10 meters,temperature controlled system,intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience,this project shows the control of that ac power applied to the devices,starting with induction motors is a very difficult task as they require more current and torque initially,this project shows the measuring of solar energy using pic microcontroller and sensors,a mobile phone might evade jamming due to the following reason.it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings,as overload may damage the transformer it is necessary to protect the transformer from an overload condition,.
