FAQ: Heading modules
What is a Heading RTK GNSS module?
What is a Heading RTK GNSS module?
A Heading RTK GNSS module is a dual-antenna receiver that delivers centimeter-level positioning accuracy while simultaneously computing the heading, pitch, and roll of a platform. Unlike a standard RTK receiver, it determines orientation by calculating the vector between two antennas — no magnetic compass required, making it immune to magnetic interference.
What is the difference between a Heading RTK module and a standard RTK GNSS receiver?
What is the difference between a Heading RTK module and a standard RTK GNSS receiver?
A standard RTK receiver outputs precise coordinates. A heading module uses two antennas and adds orientation data — heading, pitch, and roll — making it essential for applications where knowing which direction a platform faces matters as much as knowing where it is.
What heading accuracy can I expect from these modules?
What heading accuracy can I expect from these modules?
Heading accuracy typically ranges from 0.1° to 0.4° RMS and depends on the baseline distance between the two antennas. The longer the baseline, the more precise the heading. Absolute position accuracy reaches 1–2 cm with active RTK corrections.
Which chipsets are available in this collection?
Which chipsets are available in this collection?
The collection covers modules built on U-blox ZED-F9H, U-blox ZED-X20P (all-band), Unicore UM982, Septentrio mosaic-H, and mosaic-G5 P3H. ZED-F9H offers a solid price-to-performance ratio for drone applications. UM982 is a high-performance dual-channel receiver at a competitive price. mosaic-H is a professional-grade receiver with Ethernet and PoE support.
What GNSS constellations do these modules support?
What GNSS constellations do these modules support?
What GNSS constellations do these modules support? Most modules simultaneously track GPS, GLONASS, Galileo, and BeiDou. All-band modules such as the ZED-X20P also receive L1, L2, and L5 signals, which significantly improves reliability in urban canyons, under tree cover, or in other signal-degraded environments.
Which applications are Heading RTK modules designed for?
Which applications are Heading RTK modules designed for?
Primary use cases include UAVs and drones (compass-free stabilization and navigation), autonomous ground robots, self-driving vehicles, precision agriculture machinery with autopilot, surveying and mapping equipment, and marine drones. Modules with ADR/UDR support such as the NEO-M9V are also suited for urban navigation where GNSS signal may be temporarily lost.
Do these modules require an external RTK correction source to output heading?
Do these modules require an external RTK correction source to output heading?
No. The heading function operates autonomously — the two receivers compute orientation from their baseline vector without any external correction feed. RTK corrections from a base station or NTRIP/CORS service are only needed if you also want centimeter-level absolute position accuracy. Without corrections, the module still outputs heading while providing standard GNSS-level position accuracy.
What is the difference between ZED-F9H and UM982 for heading applications?
What is the difference between ZED-F9H and UM982 for heading applications?
ZED-F9H is a proven U-blox chip with wide ecosystem support, extensive documentation, and reliable integration with popular autopilot platforms like ArduPilot and PX4. UM982 from Unicore is a newer dual-channel chip that offers comparable heading accuracy, supports more constellations simultaneously, and is available at a similar price point. UM982 is a strong choice when raw multi-constellation performance matters; ZED-F9H is preferred when ecosystem compatibility and software support are the priority.
