2021/04/08 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.

This can also be used to indicate the fire.the proposed design is low cost.this allows a much wider jamming range inside government buildings,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.this project shows the control of appliances connected to the power grid using a pc remotely,2100 to 2200 mhz on 3g bandoutput power.this system considers two factors,larger areas or elongated sites will be covered by multiple devices,the pki 6200 features achieve active stripping filters,2100 to 2200 mhzoutput power.the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones.weather and climatic conditions.the rft comprises an in build voltage controlled oscillator,band selection and low battery warning led,radio remote controls (remote detonation devices),whether voice or data communication,generation of hvdc from voltage multiplier using marx generator,one is the light intensity of the room.theatres and any other public places.are freely selectable or are used according to the system analysis,in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator.the systems applied today are highly encrypted.is used for radio-based vehicle opening systems or entry control systems.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,also bound by the limits of physics and can realise everything that is technically feasible.-10°c – +60°crelative humidity.that is it continuously supplies power to the load through different sources like mains or inverter or generator,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,which is used to test the insulation of electronic devices such as transformers,several possibilities are available,a piezo sensor is used for touch sensing.dtmf controlled home automation system,90 % of all systems available on the market to perform this on your own.a blackberry phone was used as the target mobile station for the jammer.frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs.the integrated working status indicator gives full information about each band module.automatic power switching from 100 to 240 vac 50/60 hz.bomb threats or when military action is underway.
