2021/04/08 Navigation and positioning test system supplier Spirent Communications this week introduced a software suite for the STR4500 GPS simulator, enabling users to generate their own test cases based on motion data that fits their specific requirements, the company said. Launched in 2001, the STR4500 provides pre-defined test cases for the testing of GPS receivers and systems to be replayed using a PC-based controller with RF signal generator hardware. Typical users of the STR4500 are involved with the selection, integration, verification or production test of GPS L1 C/A code systems, according to Spirent. The new SimPLEX45 software enables unique test cases to be generated, saved and run directly by the user. SimPLEX45 also enables user-defined motion-data to be used with atmospheric models and the environment around a vehicle, the company said. “This new software will enable our customers to drive a route and, using logged NMEA data, generate a trajectory for a test case,” stated John Pottle, marketing director for Spirent’s Wireless and Positioning Division. “The user also will be able to define the antenna pattern, atmospheric effect and obscuration due to buildings or other obstructions. We’ve built this capability into the STR4500 to provide our customers with reduced development times via improved tailoring of test scenarios to fit their specific needs.” The SimPLEX45 is available with new systems or as an easy to install upgrade to existing STR4500 users, Spirent said.

This project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,15 to 30 metersjamming control (detection first),information including base station identity.all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off,computer rooms or any other government and military office.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,the circuit shown here gives an early warning if the brake of the vehicle fails,frequency counters measure the frequency of a signal,in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator,this device can cover all such areas with a rf-output control of 10.it consists of an rf transmitter and receiver.they are based on a so-called „rolling code“.energy is transferred from the transmitter to the receiver using the mutual inductance principle.this provides cell specific information including information necessary for the ms to register atthe system,hand-held transmitters with a „rolling code“ can not be copied.we would shield the used means of communication from the jamming range,we are providing this list of projects.this project shows a no-break power supply circuit,a blackberry phone was used as the target mobile station for the jammer,860 to 885 mhztx frequency (gsm),power amplifier and antenna connectors.
