C-RTK 9Ps Centimetre-Level GNSS Module

Multi-star multi-frequency receiver.
Centimeter-level positioning.
Dual-module direction finding.
Dual-end switching.

Multi-star Multi-Frequency High- Precision Positioning

Built-in u-blox F9P multi-star multi-frequency satellite receiver with concurrent reception of BeiDou, Galileo, GLONASS and GPS. Positioning accuracy: <0.01m +1ppm CEP.

GPS

GLONASS

Galieo

BeiDou

Convergence time is ≈ 14s

Ultra-fast positioning

Multi-satellite, multi-frequency receiver combined with advanced RTK algorithms enables the base station to complete convergence and achieve centimeter-level positioning in under 30 seconds.

Dual RTK for yaw，Adapt to complex environment

Dual C-RTK 9Ps can estimate yaw which can replace the magnetic compass. This is useful for flight in complex magnetic field environments such as close to power lines.

For use as a base station

For use as a mobile device

Fast switch between sky and rover unit

The C-RTK 9Ps adopts the same design of the two units (sky unit and rover unit), and the two unit use the same firmware. You only need to load different configuration parameters to complete the fast switching
