OGGG-BD-38(40)-M-2 is a four-system full-frequency high-precision measurement antenna supporting GPS, BDS, GLONASS, and GALILEO, which can meet the needs of BeiDou III and multi-system compatibility of measurement equipment. It can be widely used in mapping, marine survey, geological monitoring, bridge deformation monitoring, automated port, UAV, and unmanned vehicle applications.

This type of antenna has such Technical features on the following pieces:

• 1.passive antenna with high gain and wide beam, good reception of low elevation angle signal, can still receive stars generally in the more serious blocking environment.
• 2.passive antenna working bandwidth, can well support multi-system multi-frequency point work, especially the global network B3 frequency point, and L5, L-BAND frequency point, significantly improve the system's stability.
• 3.antenna out-of-band rejection is high, which can effectively avoid signal interference from communication base stations and other signals that lead to system instability.
• 4.compact and reliable structure, IP67 waterproof, dustproof, and anti-UV housing, can meet long-term use requirements in various harsh outdoor environments.
