    NavCom’s ANT-3001BR is designed to enhance and support the performance of NavCom’s precise positioning receivers. The ANT-3001BR is a high-performance geodetic choke ring antenna consist of multiple concentric rings which are designed to absorb and deflect low horizon signals that may have been reflected by surrounding terrain or structures. The result is a smooth controlled pattern with low susceptibility to multi-path interference. It is constructed to withstand harsh external environments while providing mechanical stability to support installation for CORS and other similar permanent installations. The ANT-3001BR receives multi-constellation signals including GPS, GLONASS and Galileo, as well as WAAS, EGNOS and StarFire™ plus other SBAS signals. The antenna also fully complements the SF-3050 family of Integrated StarFire Receivers. NavCom’s SF-3050 receiver, applies patented multipath mitigation that enhances the ANT-3001BR to allow for a significant reduction in the effects of multipath. Providing unsurpassed performance and reliability, NavCom’s ANT-3001BR supports reference station, CORS & OEM applications.
