N3 IMU GNSS Receiver
Product Information
- Product Name: N3 IMU GNSS Receiver
- Product Series: N Series GNSS Receiver
- Version: 2022.01.30
- Dimensions: 7.3 cm (height), 15.5 cm (width)
The N3 IMU GNSS Receiver is an ultra-reliable and compact
receiver designed to track all current and planned Global GNSS
constellations. It is equipped with the QUANTUMTM algorithm and a
second-generation SinoGNSS ASIC chip, which greatly enhances
positioning reliability and stability, especially in obstacle-rich
environments. The receiver also has L-Band capability.
It features cutting-edge IMU tilt performance and offers
flexibility for field use. The receiver is powered by two 3400mAh
hot swap batteries, allowing for extended working hours. The smart
battery design enables fluent workflow in the field. Battery
shortage is indicated by flashing battery LEDs, and users can
easily replace the batteries or charge them directly in the N3 IMU
receiver using external power.
The N3 IMU GNSS Receiver is manufactured by ComNav Technology
Ltd., a company that holds the official trademark registered in the
People’s Republic of China, EU, USA, and Canada. Please note that

Product Usage Instructions
To use the N3 IMU GNSS Receiver:
- Ensure that the receiver is placed in an open area with a clear
view of the sky for optimal signal reception. - Power on the receiver by pressing the power button.
- Wait for the receiver to initialize. The initialization time
may vary. - Once initialized, the receiver will start tracking signals from
GPS, BeiDou, GLONASS, Galileo, QZSS, IRNSS, and L-Band
constellations. - Monitor the battery status using the LED indicators. If the
battery LEDs flash, it indicates a battery shortage. - To replace the batteries, follow the instructions provided in
the user manual. - If needed, you can charge the batteries directly in the N3 IMU
receiver using external power.
For more detailed instructions and performance specifications,
please refer to the complete user manual provided with the
product.

ULTRA-RELIABLE GNSS
SinoGNSS N3 IMU GNSS Receiver is an extremely compact designed receiver, tracking all current and planned Global GNSS constellations, as well as L-Band capability. With the QUANTUMTM algorithm and second generation SinoGNSS ASIC chip inside, it largely improves positioning reliability and stability, especially in obstacle environments.
CUTTING EDGE IMU TILT PERFORMANCE
Up to 60 ° tilting compensation, no need to center the Bubble, enables N3 IMU GNSS Receiver to measure quickly and acquire the precise position easily. With in-built IMU and adopted selfdeveloped core algorithm, the N3 IMU GNSS Receiver is free of magnetic interference and calibration, and can bring accurate and reliable coordinates. One-time adjustment for successive tilting measurement with centimeter-level accuracy increases work efficiency.
FLEXIBILITY FOR FIELD USE
Featuring full-constellation tracking capability, built-in IMU, 4G/WiFi/Bluetooth® connection, and easy survey workflow with Android-based Survey Master Software, the N3 IMU GNSS receiver is one of the most reliable choices for your demanding surveying tasks. Collect more accurate data easier and faster no matter for beginners or professional surveyors. The rugged Al-mg alloy housing with IP67 Dustproof & Waterproof design makes the N3 IMU receiver perfectly and effectively work even in harsh environments.
SMART BATTERY DESIGN
With two 3400mAh hot swap batteries, the N3 IMU GNSS Receiver helps to extend working hours and ensures you fluent workflow in the field. The battery LEDs flash when battery shortage, then you can replace batteries or directly charge in N3 IMU receiver through external power.
