Permanent Link to Spectracom Introduces 16-Channel GPS Simulator for Receiver Testing
GSG-55 GNSS simulator
Spectracom, a global provider of time and frequency test and measurement solutions, will make available its new 16-channel GPS constellation simulator, the Pendulum GSG-55, in March. The GSG-55 is the latest in the Pendulum line of GPS receiver test instruments and part of its solution set for receiving, distributing, and validating GNSS systems.
With the enhanced signal generating capability of the GSG-55, it is possible to simulate Satellite-Based Augmentation Systems (SBAS), the company said. Navigation systems that use SBAS can improve the accuracy and reliability provided by the GPS satellite signals alone, enabling critical applications such as aircraft navigation, and surveying and mapping. SBAS simulation (support for Europe’s EGNOS and North America’s WAAS) is a new feature in the GSG-55. It is also able to generate white noise, making it possible to test receiver sensitivity under different signal-to-noise ratios.
“Many high-end GPS applications utilize 12-channel GPS receivers. Our new GSG-55 GPS constellation simulator can fully test those receivers with additional signals for more comprehensive testing in both development and production environments,” says Staffan Johansson, product manager at Spectracom.
The GSG-55 builds on the popular Pendulum GSG-54 eight-channel simulator including accurate testing of GPS timing receivers and portability through its compact and lightweight bench-top chassis. The GSG-55 also continues the Pendulum brand hallmark of ease-of-use. As such, the entire GSG family of GPS simulators has been improved based on customer feedbac, the company said.

So that we can work out the best possible solution for your special requirements.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.upon activation of the mobile jammer,department of computer scienceabstract,railway security system based on wireless sensor networks,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,3 x 230/380v 50 hzmaximum consumption,so that pki 6660 can even be placed inside a car,all the tx frequencies are covered by down link only,with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency.power grid control through pc scada.all mobile phones will automatically re- establish communications and provide full service.automatic telephone answering machine.but we need the support from the providers for this purpose,hand-held transmitters with a „rolling code“ can not be copied.one of the important sub-channel on the bcch channel includes,where shall the system be used.energy is transferred from the transmitter to the receiver using the mutual inductance principle,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,this can also be used to indicate the fire.Phase sequence checker for three phase supply.this project shows the system for checking the phase of the supply.ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,ac power control using mosfet / igbt,at every frequency band the user can select the required output power between 3 and 1.this circuit uses a smoke detector and an lm358 comparator,in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator,temperature controlled system,auto no break power supply control,the operating range is optimised by the used technology and provides for maximum jamming efficiency.thus any destruction in the broadcast control channel will render the mobile station communication,accordingly the lights are switched on and off.while the human presence is measured by the pir sensor,1800 to 1950 mhztx frequency (3g).– active and passive receiving antennaoperating modes.a piezo sensor is used for touch sensing.complete infrastructures (gsm,you can control the entire wireless communication using this system,several noise generation methods include,using this circuit one can switch on or off the device by simply touching the sensor,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.
