|
|
|
Full-band: GPS L1/L2/L5、BDS B1/ B2/ B3、GLONASS L1/L2、Galileo E1/E5a/E5b/E6、L-band
|
Strong anti-interference performance: The pre-filtering scheme is adopted to effectively suppress out-of-band interference |
RTK 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 |
