## **1.** Introduction 

The Ulysses miniature ultra low profile (only 10mm in height) GNSS antenna is designed for applications which require high positioning accuracy by combining signals from GPS, GLONASS, Galileo and BeiDou systems. The tiny size of this antenna allows it to be used in very space restricted environments. 

A high gain wide-band patch antenna on an integral ground delivers reliable performance. A fully IP67 waterproof rated and UV resistant enclosure allows use in outdoor environments. Mid SAW filter configuration eliminates potential LNA burn-out from nearby out of band radiated power bursts from other antennas that may be co-located nearby. 

Typical Applications Include: 

- Timing -       Precision Positioning for Robotics / Automotive 

- Telematics -       Autonomous Routing 

The antenna is manufactured to strict first tier Automotive quality controlled manufacturing process in IATF16949 approved facility. The cable and connector are fully customizable, contact your regional Taoglas customer support team for further information.
