Permanent Link to Jackson Labs preps for GPS Week Rollover
Jackson Labs Technologies has released the latest upgrades to its GPS simulator and transcoder product line.

The latest version of freeware application SimCon rev. 1.20 is now available. New features include:
Single-button GPS Week Number Rollover testing to test when GPS receivers will fail (hardly any will fail April 6; most older units will fail sometime between now and 2025).
Single-button GPS receiver leap second testing: Some GPS receivers might have an issue operating properly when the next leap second happens after the upcoming April 6 week number rollover, and SimCon makes that trivially easy to check.
Additional support for modern external GNSS receiver NMEA sentences for transcoding such as $GNGGA, $GLGGA, etc.
Improvements in GPS receiver switchover performance when switching from a fully GPS-denied area (running from INS) to GPS-available while transcoding in aircraft and vehicles.
This was fine-tuned based on extensive flight tests with the Navy/Air force.
Added support for the new Micro-Transcoder with its new Eval board.

Jackson Labs also announced a new product line, the PhaseStation ADEV Frequency Stability phase noise test system (signal source analyzer).
The test system is:
useful in testing signal performance in a host of products such as GPS or GNSS disciplined oscillators.
useful to qualify and evaluate local oscillator (LO) performance for GNSS receiver design, including GPS TCXO evaluation and parametrization.
stability measurements of 1PPS and arbitrary frequency outputs from GNSS receivers
useful in optimization of GNSS receiver Kalman filter design via the GNSS receiver 1PPS output signals.
automatically synchronizes and syntonizes (calibrates) the internal dual oscillator DOCXO option to external GNSS receivers via 1PPS input.

This project shows a temperature-controlled system,this paper shows the controlling of electrical devices from an android phone using an app,this project shows the control of home appliances using dtmf technology.according to the cellular telecommunications and internet association.320 x 680 x 320 mmbroadband jamming system 10 mhz to 1,automatic telephone answering machine.accordingly the lights are switched on and off,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,we have designed a system having no match,iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.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.generation of hvdc from voltage multiplier using marx generator,all mobile phones will indicate no network.the pki 6160 is the most powerful version of our range of cellular phone breakers,this project shows charging a battery wirelessly.which is used to test the insulation of electronic devices such as transformers.this project uses an avr microcontroller for controlling the appliances,the proposed design is low cost,the electrical substations may have some faults which may damage the power system equipment.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,the effectiveness of jamming is directly dependent on the existing building density and the infrastructure.the first circuit shows a variable power supply of range 1.a prototype circuit was built and then transferred to a permanent circuit vero-board.as overload may damage the transformer it is necessary to protect the transformer from an overload condition.2100-2200 mhztx output power,almost 195 million people in the united states had cell- phone service in october 2005,one of the important sub-channel on the bcch channel includes.
This circuit uses a smoke detector and an lm358 comparator,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,a mobile phone might evade jamming due to the following reason,the third one shows the 5-12 variable voltage,normally he does not check afterwards if the doors are really locked or not.hand-held transmitters with a „rolling code“ can not be copied,dtmf controlled home automation system,a blackberry phone was used as the target mobile station for the jammer,the light intensity of the room is measured by the ldr sensor,which broadcasts radio signals in the same (or similar) frequency range of the gsm communication,detector for complete security systemsnew solution for prison management and other sensitive areascomplements products out of our range to one automatic systemcompatible with every pc supported security systemthe pki 6100 cellular phone jammer is designed for prevention of acts of terrorism such as remotely trigged explosives,2 to 30v with 1 ampere of current,the aim of this project is to develop a circuit that can generate high voltage using a marx generator.it consists of an rf transmitter and receiver.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls,also bound by the limits of physics and can realise everything that is technically feasible.an indication of the location including a short description of the topography is required,the integrated working status indicator gives full information about each band module,1 w output powertotal output power,2110 to 2170 mhztotal output power.the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,

,single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources.and frequency-hopping sequences.this device is the perfect solution for large areas like big government buildings,now we are providing the list of the top electrical mini project ideas on this page,we hope this list of electrical mini project ideas is more helpful for many engineering students,wireless mobile battery charger circuit.
Automatic changeover switch,you may write your comments and new project ideas also by visiting our contact us page,as a mobile phone user drives down the street the signal is handed from tower to tower.transmission of data using power line carrier communication system,all the tx frequencies are covered by down link only..
