FAQ: High Precision RTK GNSS modules

What is RTK and how does it achieve centimeter-level accuracy?

RTK (Real-Time Kinematic) is a satellite positioning technique that uses correction data from a fixed base station or NTRIP network to eliminate atmospheric and orbital errors in GNSS signals. While a standard GPS receiver achieves 2–5 meter accuracy, an RTK GNSS module such as the ZED-F9P or UM982 resolves carrier phase ambiguities in real time, delivering horizontal accuracy of 1 cm + 1 ppm — suitable for surveying, precision agriculture, UAV navigation, and autonomous vehicles.

What is the difference between ZED-F9P and NEO-F9P?

Both are u-blox F9 generation multi-band RTK receivers with centimeter-level accuracy. The ZED-F9P is the full-featured variant with support for all interfaces (USB, UART, I2C, SPI), base and rover operation, and raw data output — making it the preferred choice for professional and industrial applications. The NEO-F9P is a smaller, lower-power variant in a more compact package, optimised for integration into size-constrained designs such as wearables, compact drones, and embedded modules where form factor is critical.

What is the difference between ZED-F9P and UM982?

The ZED-F9P (u-blox) and UM982 (Unicore) are both professional multi-band RTK GNSS modules with centimeter-level accuracy, but differ in key capabilities. The UM982 is a dual-antenna module based on the Nebulas IV SoC — it supports simultaneous RTK positioning and dual-antenna heading calculation from a single chip, which makes it ideal for applications requiring direction information (AGV robots, autonomous mowers, precision agriculture machinery). The ZED-F9P supports single-antenna RTK only and requires an external compass for heading. For pure positioning the two are comparable; for heading + positioning in one module, the UM982 is the better choice.

Do I need a base station to use an RTK GNSS module?

Yes — RTK requires a source of correction data. You have two options: set up your own base station using a second RTK module (e.g. a second ZED-F9P in base mode) transmitting RTCM corrections over radio or serial link; or subscribe to an NTRIP correction service, which streams corrections from a network of reference stations over the internet. For most users NTRIP is the simpler option. Without corrections, the module operates as a standard high-performance GNSS receiver with meter-level accuracy.

Which RTK GNSS module is best for drones and UAVs?

For UAV applications the ZED-F9P is the most widely used choice — it is supported natively by ArduPilot, PX4, and most professional autopilot systems, offers fast RTK convergence on moving platforms, and is available in compact EVAL board form factors with IPEX/U.FL connectors suited for drone integration. The ZED-F9H is a heading variant of the F9 platform optimised specifically for moving base applications such as UAVs requiring dual-antenna heading. For agriculture drones requiring both RTK and heading in a single module, the UM982 is also an excellent option.

What GNSS constellations do your modules support?

All high-precision RTK modules in our collection support multi-constellation reception. The ZED-F9P, NEO-F9P, UM982, and UM980 support GPS (L1/L2/L5), GLONASS (L1/L2), Galileo (E1/E5a/E5b), BeiDou (B1/B2/B3), and QZSS. Multi-constellation tracking improves satellite availability in urban canyons, under tree cover, and other challenging environments — resulting in faster RTK fix times and more robust positioning compared to single-constellation receivers.

What is the difference between NEO-M8P and ZED-F9P?

The NEO-M8P is a previous-generation single-band RTK receiver operating on L1 frequency only. It achieves centimeter-level accuracy under good sky conditions but is more susceptible to multipath errors and longer convergence times in challenging environments. The ZED-F9P is a multi-band (L1+L2 or L1+L5) receiver with significantly faster RTK initialisation, better performance in urban or obstructed environments, and support for more GNSS constellations. For new designs we recommend the ZED-F9P — the NEO-M8P remains available for existing projects or cost-sensitive applications.

What antenna do I need for an RTK GNSS module?

For RTK performance you need a multi-band active GNSS antenna that covers the frequencies used by your module. For L1/L2 RTK (ZED-F9P, UM982) you need an antenna covering at minimum GPS L1+L2 and ideally all GNSS L1/L2 bands. For L1/L5 variants, an L1/L5 multi-band antenna is required. Antenna quality directly affects RTK fix time and positioning accuracy — a high-quality survey-grade antenna with good multipath rejection will significantly outperform a basic patch antenna. We stock SMA and IPEX/U.FL connected multi-band antennas including IP67-rated helical spiral antennas for outdoor and UAV use.
