NavX-GNSS Test Solution

NavX-NTR GNSS Test Receiver

Flexibility - Scalability - Usability

Turning our test expertise into your success.
IFEN´s flexible software defined Multi-GNSS test receiver solution.

NAVX-NTR GNSS Test Receiver

  • The primary objective is to provide a high performance and fully flexible test receiver for all types of GNSS systems. Thus, the NavX-NTR fully supports all existing navigation systems.

     

    The signal processing is fully flexible. The high performance correlation engine with up to 80 channels is implemented in a powerful set of FPGAs. Signal acquisition and tracking are realized on a high performance embedded ARM Cortex A8.

  • Supporting up to 4 L-band frequencies in parallel, the NavX-NTR GNSS test receiver supports all current GNSS transmission frequencies. Due to its plug-in design, the RF front-end can easily be customized for special filtering and other frequencies.
