Four-system dual-band antenna
Supports L1 + L2 dual frequency bands, compatible with global systems such as GPS and BDS, as well as regional enhancement systems like SBAS and IRNSS, achieving high-precision positioning across multiple systems
High-precision Dual-frequency Positioning Antenna
HD GNSS L1+L2
An integrated built-in antenna specifically designed for automobiles, supporting dual-frequency high-precision positioning of GNSS (L1 + L2)
Features
01
Centimeter-level positioning accuracy
Equipped with RTK technology, the phase center accuracy reaches sub-centimeter level, maintaining high stability and repeatability
02
Strong anti-interference design
Can suppress unwanted signals and reduce the risk of system lockout
03
Robust protective structure
Core components are fully sealed, with a protection level of IP67, effectively dustproof and waterproof
04
Outstanding satellite acquisition performance
Excellent gain in each frequency band, with an axial ratio of <3dB across the entire frequency band, maintaining high stability in signal reception and output
