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. (Image: Taoglas) The new antenna range includes: The GRS.10, a smart antenna that includes a high-performance Taoglas GNSS (GPS, GLONASS, Galileo, BeiDou) ceramic patch antenna module integrated with a u-blox NEO-M8U GNSS receiver. The Torpedo series GNSS quadrifilar helical antennas, extremely high-performance wideband satellite antennas for position-information-critical applications. It provides high circularly polarized antenna gain across a wide beamwidth. These are available in a passive (QHA) or active (AQHA) versions. The BOLT A.90.A.10451111, a new GNSS timing antenna that includes lightning-induced surge protection. It is designed for the base station market. The advantage over other timing antennas is the addition of GLONASS and BeiDou frequencies. The complete range of precision GNSS antennas also includes: The MAT.12A. (Image: Taoglas) The ASFGP.36A.07.0100C, a ceramic GPS L1/L2 low-profile, low-axial-ratio, embedded stacked active patch antenna. The MAT.12A, a GPS/GLONASS/BeiDou dueling-loop chip antenna evaluation board, which delivers the advantages of a circularly polarized patch antenna with two miniaturized low-profile chip antennas on a smaller PCB footprint at one-fifth the weight. This week, Taoglas also launched small form-factor ultra-wideband (UWB) antennas designed to work with DecaWave’s chipset and module solutions for applications including asset tracking, follow-me drones, healthcare monitoring, smart home services and other applications that demand high-performance indoor localization capabilities. Taoglas’ complete range of GNSS and UWB antennas will be on display in Booth N.614 at Mobile World Congress Americas, Sept. 12-14, in San Francisco.
