Overview

This antenna is a compact seven-frequency antenna supporting GPS L1/L2, BDS B1/B2/B3, and GLONASS L1/L2, designed to meet the demands for multi-system compatibility and precision measurement in GNSS applications. Widely used in geodetic mapping, Marine survey, geological deformation monitoring, micro displacement monitoring, precision positioning, mobile mapping, large construction machinery control and fine agriculture and other fields.

Key Features

• Three systems, seven bands

GPS L1/L2, BDS B1/B2/B3 and GLONASS L1/L2

• Strong anti-interference performance

The pre-filtering scheme is adopted to effectively suppress out-of-band interference

• Millimeter positioning accuracy

Multi-feed point design and symmetrical antenna structure are adopted to realize the coincidence of phase center and geometric center, and reduce the influence of antenna on measurement error.

• Good reliability

Lightning and waterproof design.
