FEYMAN designs IMU, GNSS and vision modules engineered for centimeter-grade accuracy in surveying, robotics, UAVs, and the messy real-world conditions where positioning has to keep working.
From the IMU at the tip of an RTK pole to the vision engine that reads distant targets, and the sealed AHRS riding on a piece of construction equipment — every FEYMAN module is designed to fuse cleanly with the next, so you build positioning systems instead of integrating headaches. Select a series to filter the module index below.
Each IM-series generation tightens the dynamic attitude spec that tilt compensation lives or dies by — figures straight from the published datasheets. Our next part is in qualification now.
The module that effectively set the GNSS tilt-compensation bar. Over 100,000 units in active field service by 2023, integrated by 20+ surveying partners worldwide. Multi-jurisdiction patents and painless integration.
Low-cost, high-precision module that fuses MEMS gyro / accelerometer with GNSS RTK to deliver roll & pitch within 0.02° (2σ). Protected under US and Chinese patents. Built for machine control, robotics, drones, tilt surveys, AHRS, and dead reckoning.
Mechanically hardened 25 × 25 × 5.9 mm successor to IM19, built for the harshest industrial environments. Factory-calibrated temperature compensation across the full operating range, dynamic pitch & roll to 0.01° (2σ), gyro bias instability of 0.5 °/h, and 1000 Hz configurable output.
SMT MEMS IMU fused with GNSS RTK, engineered for tilt RTK surveys, agricultural machine automation, and dead reckoning. Delivers roll & pitch to ±0.05°, heading to ±0.5°, and 1 cm tilt-survey accuracy at up to 30° pole tilt — with 1-second initialization. Auto-steering yaw accuracy 0.5° (95%). Patents in US and China.
New-generation high-precision RTK module tracking every major constellation across all frequencies — GPS, GLONASS, GALILEO, BeiDou (B1I / B1C / B2I / B2a / B2b / B3I), QZSS, with NavIC and SBAS in development. Over 1000 tracking channels, RTK initialization in ≤5 s, sub-centimeter horizontal accuracy, LGA 54-pin at 17 × 22 × 2.4 mm.
Quad-band, full-constellation GNSS RTK module with free decimeter-level PPP. Tracks all four frequency bands across every major constellation for fast, robust convergence — and delivers decimeter accuracy out of the box via PPP, with no correction-service subscription required. Built for orientation-critical platforms: autonomous machinery, marine, and surveying rovers that need both position and precise heading.
Our next-generation RTK platform — a 2000-channel front-end designed to track every visible signal across every constellation simultaneously, for the most challenging multipath and signal-denied environments. In qualification, shipping end of 2026.
The world's lowest-power GNSS RTK and heading module with an integrated 6-axis IMU — under 100 mW at full performance, not idle. On-chip RTK, dual-antenna heading, and sensor fusion that holds up in GNSS-denied environments.
Tracks BDS, GPS, GALILEO, GLONASS and QZSS for continuous fixes through changing sky conditions. Low power, high cost-performance — well suited to wearable positioning and small UAVs.
Compact assembly that augments GNSS RTK with vision to make stakeout faster and more accurate. The system shows the surveyor exactly where the tip needs to land.
Entry-level Time-of-Flight (ToF) distance module measuring 3 to 10 meters with millimeter-class resolution. Hardware-level time sync with other FMI modules (IM, PM, VM and MC series) over a shared PPS line — so range data drops onto the same timebase as your IMU, GNSS, and vision streams.
Wide-temperature calibrated dynamic tilt and attitude reference system with 9-DoF sensing, magnetometer-aided heading without GNSS, and CANopen / J1939 over dual M12 connectors. Built for construction machinery, robotics, and machine control.
Documents for IM26, the P23 series, RM10 and MC10 are available on request — tell us what you're building and we'll send the current revision.
Our IM-series IMUs continue to set the tilt and terrain-compensation reference inside leading RTK rovers.
Explore the module families ↗Our newest SMT IMU fuses a MEMS gyro and accelerometer with GNSS RTK to hold roll and pitch within 0.02° (2σ) — built for machine control, robotics, drones, and tilt surveys.
See IM26 specs ↗How FEYMAN's hardware-agnostic stack lets surveying OEMs pick their preferred GNSS receiver without rewriting firmware.
Browse the GNSS lineup ↗Surveyors testing visual-guided pole placement reported a 2× speed gain — and a quieter learning curve for new field staff.
See VM23-AR specs ↗FEYMAN is built around six global offices — Berlin, Phoenix, Beijing, Mexico City, Colombo, and Shenzhen — placing engineering and field support on the ground in the regions our partners build in. Wherever your program runs, there's a team nearby who knows the hardware.
FEYMAN modules are deployed by integrators and OEMs across all of North America, all of Europe, South Asia, and Southeast Asia — the regions where precision positioning is scaling fastest.
I think it's much more interesting to live not knowing than to have answers which might be wrong.— R. P. Feynman
