Product details
ComNav N3 IMU
Palm-Sized High
Precision GNSS RTK Receiver
The ComNav N3 IMU is a next-generation, ultra-compact GNSS RTK receiver engineered for maximum surveyor mobility and high-precision field data acquisition. Powered by SinoGNSS® technology with an advanced 1500+ channel ASIC engine, the N3 tracks all active and planned satellite constellations simultaneously.
Combining a calibration-free 60° IMU tilt sensor, an internal UHF transceiver radio, and a rugged IP67 magnesium-aluminum alloy housing into a palm-sized chassis, the N3 delivers centimeter-level positioning accuracy in dense urban areas, thick tree canopy, and rugged terrains.
Big Performance in a Palm-Sized Form Factor
Eliminate field fatigue with ultra-lightweight, calibration-free RTK surveying
Traditional RTK rovers can be cumbersome during long field days, especially when navigating steep slopes, dense brush, or congested construction sites. Weighing under 500 grams, the ComNav N3 IMU fits in the palm of your hand while maintaining enterprise-grade positioning capability.
Equipped with an advanced, calibration-free IMU tilt sensor, the N3 allows surveyors to measure hard-to-reach points—such as building corners, underground pipe edges, and fence lines—at tilt angles up to 60° without leveling the pole bubble or worrying about magnetic interference.
Advanced SinoGNSS® Engine & Wireless Connectivity
Engineered for high productivity and reliable data collection across demanding environments:
-
1500+ Channel Tracking: Tracks GPS, GLONASS, BeiDou (B1I, B2I, B3I, B1C, B2a), Galileo, QZSS, NavIC, and SBAS for fast RTK fixed solutions.
-
Calibration-Free IMU Tilt Sensor: Instant tilt initialization allows rapid point collection while maintaining millimeter precision.
-
