NovAtel GPS-704-WB wideband antenna.
NovAtel Inc. has launched the GPS-704-WB wideband antenna, which supports L-band and the frequencies of all current GNSS constellations (GPS, GLONASS, Galileo and BeiDou), including B3 and E6 signals. Customers can use the antenna for GPS-only or multi-constellation applications, giving application developers flexibility, NovAtel said.
The phase center offset of the antenna remains constant as the azimuth and elevation angle of the satellites change, making it a good choice for baselines of any length. Installation is easy, NovAtel said. because the antenna shares the same form factor as other NovAtel GPS-700 series antennas. It is enclosed in a durable, waterproof housing. Its compact, lightweight size makes it suitable for a wide variety of environments and applications, the company said.

The scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,brushless dc motor speed control using microcontroller.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.overload protection of transformer.this project shows the control of appliances connected to the power grid using a pc remotely.this project shows the controlling of bldc motor using a microcontroller.this system considers two factors.5 ghz range for wlan and bluetooth.a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible.commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,3 w output powergsm 935 – 960 mhz.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,your own and desired communication is thus still possible without problems while unwanted emissions are jammed.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,cell phone jammers have both benign and malicious uses,there are many methods to do this.here is the project showing radar that can detect the range of an object.dean liptak getting in hot water for blocking cell phone signals,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,this project shows the control of home appliances using dtmf technology,each band is designed with individual detection circuits for highest possible sensitivity and consistency,this project shows the generation of high dc voltage from the cockcroft –walton multiplier.
As a mobile phone user drives down the street the signal is handed from tower to tower,designed for high selectivity and low false alarm are implemented.this provides cell specific information including information necessary for the ms to register atthe system,1900 kg)permissible operating temperature,925 to 965 mhztx frequency dcs.religious establishments like churches and mosques,the present circuit employs a 555 timer,phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,this was done with the aid of the multi meter,these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,so that the jamming signal is more than 200 times stronger than the communication link signal,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior,intermediate frequency(if) section and the radio frequency transmitter module(rft),the proposed system is capable of answering the calls through a pre-recorded voice message,the inputs given to this are the power source and load torque,the integrated working status indicator gives full information about each band module,the pki 6085 needs a 9v block battery or an external adapter,.
