PCTEL Inc. has launched a new GNSS multi-satellite antenna portfolio for mobile and base-station timing applications. PCTEL’s new SkyLink antenna technology features out-of-band rejection characteristics that provide exceptional GPS/Galileo and GLONASS L1 support and performance in heavy RF traffic environments for fixed and mobile timing and asset tracking applications. The new portfolio consists of two product lines: SkyCompass for fleet management and asset tracking applications SkyStamp base-station antennas for timing and synchronization of 4G LTE cellular networks. SkyCompass comprises six new configurable antenna platforms, including single-band or multiband GNSS options that address the majority of fleet management installation needs. SkyStamp offers two timing reference and synchronization antenna models that provide maximum mitigation of the effects from nearby LTE interference sources. “Over the last decade, PCTEL has been the industry’s technology leader in high rejection GPS products. These antennas are deployed worldwide by OEM customers in aviation, defense, and fleet management public safety projects,” said Rishi Bharadwaj, vice president and general manager of PCTEL’s Connected Solutions. “True to our commitment to support global communications and evolving requirements, PCTEL’s SkyLink technology provides global multi-satellite GNSS coverage and precision tracking by rejecting RF noise or interference that can negatively affect communications in performance critical situations.” SkyCompass and SkyStamp antennas will be available for shipment in November.
