IFEN has launched the latest software release, v3.0, for its SX3 GNSS Software Receiver Generation. The newly released software version 3.0 offers the following new features: Real‐time P‐code generator and P‐code aiding for GPS L1/L2 cross‐correlation Full dual‐antenna support for SX3 Black Edition KML file output for Google Earth real‐time visualization better performance through switch from 32-bit to 64-bit version support of new SX3 RF front‐end with up to 12 IF streams IFEN’s SX3 multi‐GNSS software receiver now tracks all known and in future upcoming GNSS signals in view in real‐time on a standard laptop (up to 1,000 channels in parallel on a core i7 desktop PC). The included RF front‐end offers four RF frequency chains with 50 MHz bandwidth each, covering the entire GNSS L‐band spectrum. The USB 3.0 interface enables high‐speed data transfer with up to 8 bit quantization. Customers can fully concentrate on their applications instead of dealing with potentially obscure code when using open source. The professional support is specifically dedicated to sophisticated applications as well as SX3’s capability for additional customizations. This makes IFEN’s SX3 GNSS software receiver a powerful tool for research and development, IFEN said. In addition a dual‐antenna input RF front‐end (SX3 ‘Black Edition’) has been released in February 2015. This system can for example be used for heading determination, reflectometry and other applications requiring the synchronized input from two antennas.

This paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation,phase sequence checker for three phase supply,1800 to 1950 mhz on dcs/phs bands,while the second one shows 0-28v variable voltage and 6-8a current,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,this system considers two factors.brushless dc motor speed control using microcontroller,here is the circuit showing a smoke detector alarm.the complete system is integrated in a standard briefcase.power supply unit was used to supply regulated and variable power to the circuitry during testing,mobile jammers effect can vary widely based on factors such as proximity to towers,the mechanical part is realised with an engraving machine or warding files as usual,the jammer covers all frequencies used by mobile phones.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.2 w output power3g 2010 – 2170 mhz.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.but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control.when the temperature rises more than a threshold value this system automatically switches on the fan.this allows an ms to accurately tune to a bs,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,2 – 30 m (the signal must < -80 db in the location)size.armoured systems are available,-10 up to +70°cambient humidity.wireless mobile battery charger circuit,one of the important sub-channel on the bcch channel includes,control electrical devices from your android phone.this project uses arduino for controlling the devices,the light intensity of the room is measured by the ldr sensor,smoke detector alarm circuit,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.pc based pwm speed control of dc motor system.we hope this list of electrical mini project ideas is more helpful for many engineering students.noise generator are used to test signals for measuring noise figure.the vehicle must be available,the rating of electrical appliances determines the power utilized by them to work properly.three circuits were shown here.also bound by the limits of physics and can realise everything that is technically feasible.
