Navilock, a trademark of Tragant Handels- und Beteiligungs GmbH, announces a new family of GLONASS receiver products including the NL-662U USB-based receiver, equipped with a u-blox GLONASS chipset. Since the end of 2011 the Russian satellite navigation system GLONASS has been available worldwide. Similar in functionality to the US-NAVSTAR GPS system, GLONASS satellites transmit positioning data over distinct frequencies (Frequency Division Multiple Access, or FDMA, versus GPS which uses Code Division Multiple Access, or CDMA). The new GLONASS receiver products have internal patch antenna in various configurations to serve different installation requirements. Four housing variants with USB or serial MD6/TTL interfaces are available for installation on vehicles or boats. The u-blox GLONASS chipset features high accuracy to support precision location-based applications such as navigation, datalogging or tracking. The products provide -158-dBm signal sensitivity with extremely low power consumption to insure reliable performance and long battery life. The u-blox GLONASS chipset facilitates hot starts in less than 3 seconds. For more information, visit Navilock’s website and click on “new products.”
