Orbit G5 Pro
The Orbit G5 Pro is a professional-grade GNSS module built around the Septentrio mosaic-G5 P3H — one of the most capable and resilient GNSS chipsets available for UAV applications. Paired with the STM32H743 processor, PNI RM3100 magneto-inductive magnetometer, and Infineon DPS368 barometer, and communicating entirely over DroneCAN, the G5 Pro delivers a complete navigation solution in a single module.
Unlike conventional GPS modules that rely on a separate moving baseline setup with two external units, the Orbit G5 Pro integrates dual-antenna heading natively within a single module. This makes it the ideal primary navigation unit for large multirotors, fixed-wing aircraft, VTOL platforms, and any mission-critical system where positioning integrity cannot be compromised.
Key Features
- Septentrio mosaic-G5 P3H GNSS: Quad-band, multi-constellation receiver with 789 hardware channels and best-in-class RTK centimeter-level accuracy
- Integrated Dual-Antenna Heading: Native heading and pitch/roll output from a single module — no second GPS unit required
- AIM+ Anti-Jamming & Anti-Spoofing: Septentrio’s patented interference mitigation technology for resilient operation in RF-contested environments
- LOCK+: Superior signal tracking under heavy mechanical shock and vibration
- APME+ Multipath Mitigation: Advanced filtering of signals reflected from nearby structures
- IONO+ Ionospheric Protection: Robust positioning during ionospheric disturbances
- RM3100 Magnetometer: Magneto-inductive technology with 10 nT resolution — 33× lower noise than conventional Hall-effect sensors, with zero drift and zero hysteresis
- DPS368 Barometer: High-precision pressure sensing with ±0.06 hPa relative accuracy
- STM32H743 Processor: High-performance 32-bit ARM Cortex-M7 for reliable onboard sensor fusion and DroneCAN communication
- DroneCAN Interface: Plug-and-play integration with ArduPilot and PX4 flight stacks
- RTK Support: Centimeter-level positioning accuracy with fast 7-second initialization
- High Update Rate: Position output at up to 20 Hz for highly dynamic applications
- Ultra-Low Latency: Less than 10 ms positioning latency for stable, precise control loops
Typical Applications
- Large Multirotors & Heavy-Lift Platforms — Single-module heading and positioning with no secondary GPS required
- Fixed-Wing & VTOL Aircraft — Accurate heading independent of magnetic field for carbon-fiber airframes and electrically noisy environments
- Autonomous Navigation Systems — Resilient, high-integrity GNSS for systems operating in GPS-contested or jamming-prone areas
- Survey & Mapping UAVs — Centimeter-level RTK positioning with pitch and roll attitude output for precision data collection
- Long-Range & BVLOS Operations — Reliable heading and positioning where GPS signal integrity is critical
