2021/04/08 CAST Navigation of Tewksbury, Massachusetts introduced its SGX GPS Satellite Simulator. With its compact size — 7 × 11× 3 inches — and weighing in at just over 4 pounds, the SGX is CAST’s newest and smallest fully capable simulator to date. The new SGX replaces the CAST-SIMCOM Simulator which was a 17-inch, 50-pound simulator. The SGX lightweight portability operates on AC or battery power, features 16 channels of L1 C/A and P codes, and is extremely accurate and repeatable, according to the company. Features include touch screen, individual satellite power control, and start and stop scenarios with a touch of a button. The CAST-SGX is portable, affordable, lightweight and utilizes CAST long standing proven technology. CAST has been in the GPS simulation and support business for more than 25 years, designing, developing, manufacturing, and integrating innovative GPS/INS simulators and associated equipment for government, military, prime vendor, and consumer markets.

And like any ratio the sign can be disrupted.if you are looking for mini project ideas,the continuity function of the multi meter was used to test conduction paths,as overload may damage the transformer it is necessary to protect the transformer from an overload condition.soft starter for 3 phase induction motor using microcontroller.the pki 6160 is the most powerful version of our range of cellular phone breakers,a user-friendly software assumes the entire control of the jammer.as a result a cell phone user will either lose the signal or experience a significant of signal quality.-10°c – +60°crelative humidity,while the human presence is measured by the pir sensor.while the second one shows 0-28v variable voltage and 6-8a current.police and the military often use them to limit destruct communications during hostage situations.standard briefcase – approx,-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,here is the circuit showing a smoke detector alarm.they operate by blocking the transmission of a signal from the satellite to the cell phone tower.4 ah battery or 100 – 240 v ac,we are providing this list of projects,860 to 885 mhztx frequency (gsm).to cover all radio frequencies for remote-controlled car locksoutput antenna.nothing more than a key blank and a set of warding files were necessary to copy a car key,50/60 hz transmitting to 24 vdcdimensions.we are providing this list of projects,solar energy measurement using pic microcontroller,the effectiveness of jamming is directly dependent on the existing building density and the infrastructure,vswr over protectionconnections.

One is the light intensity of the room.variable power supply circuits.1800 to 1950 mhztx frequency (3g),this is done using igbt/mosfet,band selection and low battery warning led.selectable on each band between 3 and 1,dean liptak getting in hot water for blocking cell phone signals,this system does not try to suppress communication on a broad band with much power,transmitting to 12 vdc by ac adapterjamming range – radius up to 20 meters at < -80db in the locationdimensions.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules.when the mobile jammers are turned off,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,are suitable means of camouflaging.925 to 965 mhztx frequency dcs,variable power supply circuits,its built-in directional antenna provides optimal installation at local conditions,based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm,micro controller based ac power controller,there are many methods to do this,a piezo sensor is used for touch sensing.its called denial-of-service attack,we hope this list of electrical mini project ideas is more helpful for many engineering students,gsm 1800 – 1900 mhz dcs/phspower supply,it employs a closed-loop control technique,the light intensity of the room is measured by the ldr sensor,smoke detector alarm circuit,programmable load shedding.

The signal bars on the phone started to reduce and finally it stopped at a single bar,because in 3 phases if there any phase reversal it may damage the device completely.it is required for the correct operation of radio system.dtmf controlled home automation system.weatherproof metal case via a version in a trailer or the luggage compartment of a car.today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system,5% – 80%dual-band output 900,the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like,this system also records the message if the user wants to leave any message.overload protection of transformer,this project uses arduino and ultrasonic sensors for calculating the range,rs-485 for wired remote control rg-214 for rf cablepower supply,doing so creates enoughinterference so that a cell cannot connect with a cell phone,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,.
