PCTEL Inc. has launched a new series of multi-GNSS L1/L2/L5 antennas for precision navigation and timing. According to the company, the antennas combine aerospace-level precision with global satellite compatibility, in a highly durable package. They enable critical applications including vehicular automation, 5G network timing synchronization and Positive Train Control (PTC) systems. The company made the announcement at the RSSI C&S Exhibition (Railway Systems Suppliers Inc.) being held this week in Omaha, Nebraska. PCTEL’s multi-GNSS L1/L2/L5 antennas increase the accuracy of timing and location information by providing simultaneous access to multiple GNSS signals across multiple frequency bands. The antennas support all relevant GPS, GLONASS, BeiDou and Galileo frequencies with excellent multipath mitigation and high out-of-band rejection for greater signal clarity, the company said. Their robust AAR and IP67-compliant design makes them suitable for years of use on railways and in other harsh real-world environments. “Precision navigation is crucial for the next generation of autonomous vehicle technologies, which could drive major improvements in safety and efficiency across a wide variety of industries,” said Rishi Bharadwaj, senior vice president and general manager of PCTEL’s Connected Solutions group. “PCTEL’s new antennas make precision navigation accessible for large-scale deployments in rail, public safety, agricultural and commercial fleets. They also enable commercial deployments of 5G networks, which have higher accuracy requirements for network timing.” Earlier this month, PCTEL released its 900-MHz MIMO Yagi antennas with dual polarization., designed for use with MIMO or diversity radios in advanced supervisory control and data acquisition (SCADA) systems and other industrial internet of things applications. PCTEL’s dual polarized antenna technology improves data throughput and reliability on both licensed and unlicensed spectrum. PCTEL is displaying its new multi-GNSS antennas along with other antenna solutions for the rail industry, May 22-23 at the RSSI C&S Exhibition, booth #1109. The new antennas will be available for purchase in mid-July.
