The VEXXIS OEM-GNSS-503 antenna from NovAtel is now available as an OEM model for integrators. The antenna integrates into purpose-built solutions and pairs with a variety of receivers. With form-factor flexibility, the GNSS-503 antenna enables reliable performance for diverse applications.
Description
Overview
The OEM-GNSS-503 GNSS antenna module from NovAtel provides VEXXIS antenna technology in an easy to integrate assembly ideal for use in ground vehicle applications such as agriculture, machine control and mobile mapping. The OEM-GNSS-503 offers maximum flexibility when creating high performance antenna and smart antenna products using your own industrial design.
When integrated into a properly designed enclosure, the GNSS-500 series sub-assemblies have been shown to endure over 1000 hours of intense vibration testing to earn a MIL-STD-810G rating.
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.
Features
- Supports multi-frequency GPS, GLONASS, Galileo, BeiDou, QZSS and IRNSS/NavIC signal reception
- L-Band capable, supporting correction services such as TerraStar
- Multi-point antenna feed provides stable phase centre and enhanced multipath rejection
- Designed for high quality performance when used with NovAtel’s STEADYLINE technology
- Compact, lightweight assembly with single DC/RF cable eases integration into various enclosures and applications
