H-RTK ZED-F9P Ultralight

The H-RTK ZED-F9P Ultralight is a high-precision RTK GNSS rover module designed for UAVs, VTOL aircraft, fixed-wing drones, and autonomous platforms where low weight and accurate positioning are essential.

Built around the u-blox ZED-F9P GNSS receiver, the module combines multi-band RTK positioning, an integrated helical antenna, and an IST8310 compass in an ultra-lightweight design weighing less than 25 g.

Ultra-Lightweight RTK Rover

The H-RTK ZED-F9P Ultralight is specifically designed for weight-sensitive aircraft applications.

Its compact and lightweight construction helps reduce the impact on aircraft payload capacity while maintaining professional-grade RTK positioning performance.

The module is designed for rover use on the aircraft and operates with correction data provided by a compatible RTK base station or correction service.

Centimeter-Level RTK Positioning

The integrated u-blox ZED-F9P receiver provides high-precision multi-band GNSS positioning.

When used with valid RTK correction data, the module can achieve horizontal positioning accuracy of up to 1 cm + 1 ppm.

This makes it suitable for professional applications such as aerial mapping, surveying, precision agriculture, inspection, autonomous navigation, and repeatable flight missions.

Multi-Band & Multi-Constellation GNSS

The H-RTK ZED-F9P Ultralight supports GPS, QZSS, GLONASS, Galileo, and BeiDou satellite systems.

Its multi-band RF architecture allows the major GNSS constellations to be received and processed concurrently, improving satellite availability, positioning reliability, and navigation performance in demanding environments.

Integrated Helical Antenna

The integrated helical antenna provides a compact all-in-one installation without requiring an external antenna.

Its design is well suited to UAV platforms where installation space and weight must be minimized.

Integrated IST8310 Compass

The built-in IST8310 compass provides heading information to compatible flight controllers.

Combining GNSS positioning and compass data in one lightweight module helps simplify installation and improve autonomous navigation performance.

Fast Position Acquisition

The ZED-F9P receiver provides fast satellite acquisition and reliable positioning performance.

Cold start acquisition takes up to 35 seconds, while hot start acquisition can be completed in approximately 1 second under suitable signal conditions.

High Navigation Update Rates

The module supports high-rate navigation data for dynamic UAV applications.

Maximum update rates can reach 25 Hz for raw GNSS data, 20 Hz for RTK positioning, and 8 Hz for Moving Baseline operation when configured in GPS-only mode.

Professional UAV Applications

The H-RTK ZED-F9P Ultralight is ideal for lightweight UAVs, VTOL aircraft, fixed-wing drones, mapping platforms, inspection aircraft, precision agriculture systems, and autonomous vehicles requiring accurate RTK positioning with minimal additional weight.
