The Taoglas Colosseum AQHA.50 multi-band GNSS active antenna has been carefully designed to work well

on multiple GPS, GLONASS, Galileo and BeiDou bands, leading to higher location accuracy and stability of

tracking in urban environments. The quad helix antenna design has an even gain across the hemisphere giving

almost excellent and broad axial ratio which makes it resilient to multipath rejection.

The Colosseums internal LNA provides excellent out of band rejection performance providing excellent

positioning stability and reliability of GNSS signals. The robust, vandal resistant, permanent mount IP67 rated

enclosure is just 57mm in height and designed for ease of installation and can be mounted on any surface,

though performance is limited when mounted on metal surfaces.

The AQHA.50 is the latest external addition to an ongoing product road map of high precision antennas by

Taoglas. Typical Applications Include:

• Autonomous Driving

• Precision Positioning for Robotics

• Precision Agriculture

• Inventory Management & Container tracking

• Telematics & Asset Tracking

• Timing Accuracy Synchronization

For RTK applications when used on the base and/or the rover, the AQHA.50 can achieve genuine centimetre

level accuracy.

Cable and connectors are customizable. Please contact your regional Taoglas customer support team for
