q-max.base · Product No. QM2001A

Multi-Band RTK GNSS Module With Integrated IMU

Engineered for precision agriculture, surveying, and autonomous robotics, the q-max.base delivers centimeter-level RTK fix across L1/L2/L5 bands. Integrated industrial-grade IMU maintains heading under canopy and during GNSS outages, eliminating position drift when the sky is blocked.

q-max.base Field-Proven Advantages

Multi-frequency, multi-constellation high-precision GNSS evaluation platform with full RTK capability, hardware anti-interference, and a complete host-side toolchain.

Full-Constellation GNSS

GPS, GLONASS, Galileo, BeiDou, QZSS and more — with Stand-Alone, DGPS, SBAS, RTK and PPP positioning modes.

RTK Base & Rover

Operates as a base station outputting RTCMv3 corrections, or as a rover with CORS via NTRIP for centimeter-level RTK-Fixed positioning.

Multi-Format Output

Configurable NMEA-0183, proprietary SBF raw observations and RTCM corrections — plus TF-Card offline logging.

Hardware Anti-Interference

Wide-band interference mitigation, 3 auto notch filters and code/carrier-phase multipath suppression for harsh environments.

Timing & Event Sync

Configurable 1PPS output and external event triggers to tag position snapshots for multi-sensor time alignment.

Rich Interfaces

Micro-USB dual virtual COM + Ethernet, multiple 3.3V-TTL UARTs for direct MCU and flight-controller integration.
