GNSS-502 Product Sheet

GNSS-502
High-performance antenna forterrestrial applications
Patented technology
The VEXXIS GNSS-500 series antennas provide outstanding circularly polarized,
symmetric radiation patterns with superior multipath rejection performance. Thisis achieved with a patented, multi-point feeding network which provides uniquely
low loss and frequency independent amplitude/phase balance. Strictly balancing
signals and sequentially feeding the GNSS antenna at multiple points is the key toachieving remarkable performance.

Optimised for terrestrial applications
The GNSS-502 antenna is designed with a low profile, aerodynamic enclosure,ideal for ground vehicles in applications such as agriculture, machine control
and mobile mapping. Magnetic mounts make the antenna easy to install or move
between ground vehicle platforms. The combination of intelligent enclosure design
along with multi‑constellation and L-Band support makes it ideal for any terrestrial
application.

Ruggedized for challenging environments
The GNSS-502 has been thoroughly tested to withstand even the most challenging
environments. It endured over 1000 hours of intense vibration testing to earn its
MIL-STD-810G rating. It is also water resistant under heavy rainfall or high pressure
spray, ensuring its long survivability under the toughest operating conditions.
