NovAtel Antennas


The VEXXIS GNSS-502 antenna from NovAtel is perfect to use for ground vehicles in applications such as mobile mapping, agriculture and machine control. Its design makes it easy to install or move between ground vehicle platforms with magnetic mounting options.

The GNSS-501 antenna supports dual-frequency GPS (L1, L2), GLONASS (L1, L2), Galileo (E1, E5b), BeiDou (B1, B2) and L-Band signal reception.

The antenna has an IP67 rating and is ruggedized for use in harsh environments. Its MIL-STD-810G rating has been earned through 1000 hours of intense vibration testing. Moreover, its water-resistant design allows it to operate even under high pressure spray or heavy rainfall.

The superior multi-path signal rejection of the GNSS-502 provides excellent circularly polarized, symmetric radiation patterns. The key to achieving extraordinary performance is strictly balancing the signals and feeding the antenna at multiple points. The multi-point feeding network provides very low loss and frequency independent amplitude/phase balance.


  • Supports dual-frequency GPS, GLONASS, Galileo, BeiDou and SBAS signal reception

  • L-Band signal reception, supporting correction services such as TerraStar

  • Multi-point antenna feed provides stable phase center and enhanced multipath rejection

  • Designed for high quality performance when used with NovAtel’s STEADYLINE technology

  • Low-profile design ideal for machine control applications
