GNSS Antennas
Reliable GNSS positioning starts with the right antenna
GNSS Antennas
High-precision positioning starts with the right GNSS antenna. ANavS GNSS antennas are designed for RTK, PPP and multi-sensor navigation systems where stable signal reception, multipath suppression and a stable phase center are critical for accurate positioning.
GNSS Antennas
Even the best GNSS receiver cannot compensate for poor signal quality. Multipath reflections, weak satellite visibility, interference and unsuitable antenna selection can significantly reduce positioning accuracy, RTK performance and overall system reliability.
ANavS offers a range of high-performance GNSS antennas designed to maximize signal quality and positioning accuracy in demanding environments. With advanced technologies such as multipath suppression, phase center stability and multi-constellation support, our antennas provide reliable GNSS reception for RTK, PPP and GNSS/INS applications.
To meet different application requirements, ANavS provides carefully selected antenna solutions from trusted manufacturers such as Harxon, Tallysman and NovAtel, ensuring the right balance of performance, accuracy and reliability for every project.

Why the antenna is just as important as the GNSS receiver
Even the best GNSS receiver cannot achieve centimeter-level positioning if the antenna introduces signal errors.
ANavS antennas are designed to provide
- stable phase center characteristics
- excellent low-elevation satellite tracking
- effective multipath suppression
- high gain across multiple GNSS frequencies
- reliable operation in harsh environments
This ensures reliable RTK positioning even in demanding applications such as autonomous vehicles, surveying, robotics and infrastructure monitoring.
