Portable gsm jammer - jammer gsm e gps devices

Telit, a global enable of the internet of things (IoT), has debuted its SE878Kx-A series of GPS and GNSS integrated antenna receiver modules for consumer and business applications. According to the company, these modules provide high performance, maximum reliability and low power consumption. In addition, the SE878K3-A and SE878K7-A are compatible with GPS, GLONASS, Beidou and Galileo and also enable device vendors to develop quickly and cost-effectively location-based IoT solutions for use in virtually any country worldwide, Telit said. The SE878Kx-A series supports dual internal-external antennas to ensure connectivity when one is broken or compromised, along with a SAW filter to maximize jamming immunity. According to Telit, these features make the modules ideal for mission-critical applications and other use cases where reliability is key, such as alarms, stolen cars or high-end asset tracking. The SE878Kx-A series also provides seamless integration with Telit’s cellular modules, including eCall/ERA-GLONASS compliant solutions. “The new SE878Kx-A series is the latest example of Telit’s leadership in providing GNSS solutions for applications that demand the highest reliability and performance,” said Yossi Moscovitz, Telit president of products and solutions. “Just as important, the modules give IoT designers maximum flexibility, faster development cycles, easier integration and the ability to develop once and deploy worldwide.”
