Permanent Link to IP-Solutions launches new GNSS RF simulator
Portos Team paired with the Ninja. (Photo: iP-Solutions)
Japan-based iP-Solutions has introduced Portos Team, a new GNSS RF signal record-and-playback system.
The Portos Team can record and play back — or simulate —multi-frequency, multi-system GNSS signals when paired with the company’s Replicator. It can do the same for CRPA signals when paired with the Ninja (see photo).
The Portos itself can also operate as multi-frequency or CRPA front-end for a GNSS software receiver.
The high-end Ninja simulator allows for multi-antenna controlled radiation pattern antenna (CRPA) and local-area augmentation system (LAAS) simulation, the company said.
The 24-channel Replicator — developed in collaboration with the Japan Aerospace Exploration Agency (JAXA) — provides real-time generation of GNSS signals, recording and playback of dual-frequency GNSS RF signals, and GNSS RF signal analysis with JAXA COSMODE ionospheric scintillation monitor.
