3g signal jammer circuit - 2.4 ghz signal jammer

The AsteRx-m UAS by Septentrio. Septentrio’s low-power AsteRx-m OEM GNSS board has been selected by Xeos Technologies for use in its new Resolute reference receivers. Designed for high-precision monitoring in low-power applications, the Resolute systems are aimed at structural monitoring and geodetic research in remote locations. Smaller than a standard credit card, the AsteRx-m board provides centimeter-level dual-frequency L1/L2 GNSS positioning while consuming less than 0.6 W. It incorporates Septentrio’s proprietary tracking and positioning algorithms, providing high accuracy and robust performance in difficult environments. The Xeos Resolute GNSS receiver is designed for applications such as critical infrastructure monitoring, subsidence monitoring and GPS geodesy in extreme polar environments. The small, lightweight and low-power monitoring station is suitable for solar-powered remote autonomous installations. In addition to the Septentrio AsteRx-m GNSS board, the Resolute system features dual SD card storage of GNSS data and multiple telemetry options such as Iridium, cellular, Wi-Fi and wireless mesh networks for monitoring, control and data transmission. The Xeos Resolute also features multiple interfaces including USB, RS-232, RS-485, CANBUS and SDI-12. “Field tests of the prototype Resolute stations have demonstrated reliable RTK centimeter-level performance for remote deformation monitoring,” said Paul Passmore, Xeos Technologies. “We look forward to presenting our test results at the American Geophysical Union Fall Meeting in San Francisco this week.” “Xeos Technologies’ Resolute autonomous polar monitoring system is an ideal application for the AsteRx-m technology,” said Neil Vancans, vice president of Septentrio Americas. “The compact AsteRx-m delivers reliable centimeter-level L1/L2 RTK at under 0.6 W in extreme climatic conditions.” “Building upon our polar Iridium telemetry products, we are teaming with Septentrio to offer a new line of high-performance, low-power GNSS products for remote applications” said Derek Inglis, president of Xeos Technologies.
