GPS4 Receiver Module (Cod. 601090)

Flybox GPS4 Receiver Module (Cod. 601090)

The Flybox GPS4 (Cod. 601090) is an active 72-channel concurrent GNSS receiver module designed to provide high-precision satellite positioning and ground speed data directly to Flybox Oblò PFD, Vigilus EIS, and Omnia series instruments. Supplying standard RS232 NMEA-0183 sentences, it enables ground tracking and magnetic declination calculation on the Oblò, and unlocks live flight range and waypoint reserve calculations on Vigilus and Omnia Fuel Computers.

Unlocked System Capabilities Across Flybox Instruments

The GPS4 receiver feeds live NMEA telemetry to enable critical flight management functions:

• Flybox Oblò PFD / EFIS: Unlocks real-time ground Track (TRK) indications, provides automatic real-time correction of magnetic declination, and facilitates the automated magnetic compass calibration procedure.
• Flybox Vigilus EIS: Supplies true Ground Speed (GS) to calculate dynamic flight range (km or NM) and compute projected fuel reserves remaining at destination waypoints.
• Flybox Omnia Fuel Computer (57 mm & 80 mm): Plugs directly into Pin 11 (COM1 RX) on the 22-pole harness to drive the live RANGE page and calculate waypoint fuel reserves.
• Flybox Omnia CHRONO: Delivers high-precision atomic satellite time references to automatically synchronise local and Zulu cockpit clocks.

Installation Advisory: Mount the GPS4 module with the top curved surface oriented skyward, positioned on the glare shield or underneath a non-metallic composite canopy/cowl with an unobstructed view of the sky. Avoid installing within 30 cm of transmitting antennas or high-current electrical cables. In the host Flybox instrument settings, verify that the serial COM port baud rate is set to 9600 bps.
