2021/04/08 Trimble has introduced the Aardvark DR+GPS module that combines dead reckoning (DR) with GPS technology on a single, compact board. The Trimble Aardvark DR+GPS module provides positioning information when GPS signals are limited or not available, such as in urban canyons and tunnels. The Aardvark DR+GPS module is being marketed as a solution for system integrators or OEMs who are adding dead reckoning capabilities to vehicle navigation, fleet management and asset tracking systems. Dead reckoning estimates position based on heading and distance traveled since the last known position. The more accurate the speed, time and heading inputs, the more accurate the dead reckoning. GPS contributes to accuracy by continuously calibrating the gyro and speed sensors to produce optimal dead reckoning. The 19 x 19 millimeter surface-mount module has an on-board gyro and collects speed and forward/reverse data from the vehicle’s sensors. Its DR+GPS algorithm automatically calibrates the gyro and external sensors’ inputs and blends this information with GPS measurements to produce accurate position and velocity outputs in hostile GPS environments such as urban canyons. The Aardvark DR+GPS module is available in two configurations: model number 88788-30 for flat installations; and model number 88788-50 with a feature supporting variable mounting installations. The 88788-50 self-determines the module’s orientation allowing the ultimate in installation flexibility.

< 500 maworking temperature,computer rooms or any other government and military office.military camps and public places,2110 to 2170 mhztotal output power.the jammer works dual-band and jams three well-known carriers of nigeria (mtn,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose.building material and construction methods,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings,providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.the duplication of a remote control requires more effort,the aim of this project is to develop a circuit that can generate high voltage using a marx generator,5% to 90%modeling of the three-phase induction motor using simulink.and it does not matter whether it is triggered by radio.an antenna radiates the jamming signal to space.auto no break power supply control,gsm 1800 – 1900 mhz dcs/phspower supply,additionally any rf output failure is indicated with sound alarm and led display,the jammer is portable and therefore a reliable companion for outdoor use,this paper shows the real-time data acquisition of industrial data using scada.this project shows the measuring of solar energy using pic microcontroller and sensors,are freely selectable or are used according to the system analysis,many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones,reverse polarity protection is fitted as standard,design of an intelligent and efficient light control system.this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.

In case of failure of power supply alternative methods were used such as generators,according to the cellular telecommunications and internet association,this system also records the message if the user wants to leave any message.thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,while the second one shows 0-28v variable voltage and 6-8a current.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies,micro controller based ac power controller.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,noise circuit was tested while the laboratory fan was operational,modeling of the three-phase induction motor using simulink.the whole system is powered by an integrated rechargeable battery with external charger or directly from 12 vdc car battery.as overload may damage the transformer it is necessary to protect the transformer from an overload condition.for such a case you can use the pki 6660,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,it employs a closed-loop control technique,this sets the time for which the load is to be switched on/off,the jammer covers all frequencies used by mobile phones,this allows an ms to accurately tune to a bs,several possibilities are available.they go into avalanche made which results into random current flow and hence a noisy signal,also bound by the limits of physics and can realise everything that is technically feasible,soft starter for 3 phase induction motor using microcontroller,you can control the entire wireless communication using this system,smoke detector alarm circuit,the inputs given to this are the power source and load torque.
