CHCNAV M722

Explore our FAQs

• 1. Which BeiDou signals does the M722 support? Is full BeiDou coverage available?

  The M722 supports BeiDou B1I, B2I, B3I, B1C, B2a and B2b signals, together with multi-frequency signals from GPS, GLONASS, Galileo, QZSS, NavIC and SBAS. Its multi-frequency, multi-constellation tracking capability increases satellite availability and helps maintain more robust positioning in partially obstructed or challenging GNSS environments.

• 2. What positioning accuracy can the M722 achieve?

  The M722 supports multiple positioning modes depending on the available correction source. Standard single-point positioning provides accuracy of approximately 1.5 m horizontal and 2.5 m vertical. With RTK corrections, accuracy can reach 0.8 cm + 1 ppm horizontal and 1.5 cm + 1 ppm vertical. When using supported PPP-RTK corrections, the M722 can achieve 2.5 cm horizontal and 5 cm vertical accuracy, with convergence in under one minute under specified service and operating conditions.

• 3. Can the M722 achieve centimeter-level positioning without cellular coverage?

  Yes. When paired with a compatible L-Band antenna and supported satellite correction service, the M722 can provide high-accuracy positioning without a cellular or internet connection. It supports CHCNAV PointSky as well as compatible satellite-delivered correction services including BeiDou PPP-B2b, Galileo HAS and QZSS CLAS.

• 4. What applications is the M722 designed for?

  The M722 is designed for OEM applications that require both high-accuracy positioning and precise GNSS heading. Typical applications include robotic lawnmowers, precision agriculture equipment, UAVs and other autonomous or automated systems.
  
  Its compact dual-antenna architecture, multi-source correction support and interference mitigation capabilities make it particularly suitable for platforms that need reliable positioning and orientation across changing operating environments.

• 5. What is the price of the CHCNAV M722?

  The price of the CHCNAV M722 depends on the selected configuration, order volume and project requirements. For detailed pricing, integration options and availability, please contact CHC Navigation through the inquiry page or your local authorized CHCNAV representative.
