Antennas GNSS-502
HIGH PERFORMANCE ANTENNA
FOR TERRESTRIAL APPLICATIONS
PATENTED TECHNOLOGY
The VEXXIS GNSS-500 series antennas provide outstanding circularly polarized,
symmetric radiation patterns with superior multipath rejection performance. This is
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 to achieving
remarkable performance.
OPTIMIZED 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.
