Product Introduction

Four-star multi-frequency external test antenna: The antenna can receive GPS L1/L2, GLONASS G1/G2, Beidou II B1/B2/B3 signals, and is compatible with the GALILEO E1/E5a/E5b system frequency band. It can be widely used in geodetic survey, bridge construction, road construction, infrastructure, ocean survey, underwater terrain survey, driving school road test, terminal container operation and other occasions. Suitable for three-system and four-system high-precision surveying and mapping fields. ·
The antenna has high precision, low delay, high gain, good gain at low elevation angles, wide-angle circular polarization, and stable phase center. The antenna part adopts a multi-feed design scheme to ensure that the phase center and the geometric center coincide, minimizing the impact of the antenna on measurement errors and improving measurement accuracy. Built-in low-noise amplifier module.
