Why Navifort
Built for demanding signal environments
Multi-constellation coverage
Simultaneous reception across BDS, GPS and Galileo for dependable positioning wherever the platform operates.
CRPA interference rejection
Controlled reception pattern antenna technology that helps maintain a stable fix in congested signal environments.
Right-sized for the platform
Seven form factors, from a 120 g micro unit to a fixed-installation unit for reference and monitoring sites.
Field-hardened build
Sealed enclosures validated from −40 °C to +70 °C with salt-fog and vibration testing in our reliability lab.
