The BOLT A.90.A.10451111. (Image: Taoglas) Taoglas, a provider of IoT and M2M antenna products, has launched a range of high-performance GNSS antennas specifically designed to power the next generation of applications that require highly accurate location capabilities. These applications include navigation, unmanned aerial vehicles (UAVs), surveying, agriculture, connected cars and autonomous vehicles. The new antenna range is Taoglas’ most comprehensive series of high-precision GNSS antennas and incorporates new form factors and use of multiple RF bands. Taoglas’ new range includes systems and antennas that use Galileo, GLONASS and BeiDou, as well as GPS L2 or L5 bands. “Today’s connected devices and applications demand new ways of approaching the age-old problem of location accuracy,” said Dermot O’Shea, co-CEO for Taoglas. “In certain applications, there is simply no room for positioning errors — location accuracy is an absolute requirement.” The GRS.10 smart antenna.
