Can you buy a cell phone jammer

2021/04/08 M3 Systems is now offering the StellaNGC multi-constellation GNSS simulator based on the National Instruments (NI) vector signal transceiver. The simulator is designed for the testing of satellite navigation receivers for GPS, GLONASS, Galileo, and EGNOS/WAAS. It is designed to improve performance, scalability, and versatility, and reduce cost over existing navigation test solutions. GNSS is the predominant technology today for navigation and outdoor positioning. However, given the weakness of GNSS signals, receiver performance is often affected by interference from the local environment and propagation channel conditions. Understanding the effects of this interference is of particular importance not only for existing GNSS signals but also for future signals that will appear with the deployment of new constellations such as Galileo. To properly characterize receiver performance under varying conditions, the StellaGNC multi-constellation GNSS simulator provides signal generation, signal recording and replay, interference generation, signal and data processing, and complete analysis tools. The StellaNGC simulator is based on the NI vector signal transceiver in PXI for improved performance and full simulation capabilities. For record and playback only, a scaled-down version is also available based on the NI USRP (Universal Software Radio Peripheral). Both options were developed with NI LabVIEW and benefit from the performance and flexibility of the NI RF platform. The simulator provides a scalable solution that allows easy signal additions through software upgrades, multi-frequency, processing extensions with the addition of FPGAs with NI FlexRIO, and an HDD extension for storage increase. Because the simulator is based on the open PXI standard, the hardware investment can also be extended to other applications, such as simulation, record and playback, or payload simulation.
