Product Description

This antenna covers satellite navigation signals in frequency bands such as BDS B1/B2/B3, GPS L1/L2/L5, GLONASS L1/L2/L3, GALILEO E1/E5a/E5b/E6, QZSS L1/L2/L3/L6, SBAS L1/L5, IRNSS L5, and L-Band, and is compatible with multiple system receivers at domestic and overseas. It has a stable and reliable structure, is resistant to vibration and shock, and has excellent durability. It also adopts a waterproof design, which supports high-precision positioning services in complex outdoor environments.



Key Feature

Ø The multi-feed point technology has a more accurate phase value and reduces the impact of the antenna on the survey error.

Ø Supports BDS, GPS, GLONASS, GALILEO, QZSS, SBAS, IRNSS and L-Band multi-system compatibility.

Ø The stable structure design has strong anti-vibration and shock resistance, and is suitable for various harsh environments. It is the preferred choice for most construction machinery high-precision operations..

Ø Waterproof sealing design to support various outdoor environments.
