C-RTK 9Ps

Centimetre-Level GNSS Module

Introduction

The C-RTK 9Ps is a four-star Real Time GNSS system, using two c-RTK 9Ps modules, one for the aircraft and the other for the base station. It also supports dual GPS for yaw which can replace the magnetic compass. This is useful for flight in complex magnetic field environments such as close to power lines. Compared to C-RTK 9P, C-RTK 9Ps achieves similar performance at a lower price. It is a very cost-effective centimeter-level positioning module compatible with PX4/ ArduPilot open-source flight controllers. It is an ideal choice for UAV mapping, agricultural applications, high-precision takeoff and landing, ship takeoff and landing and other applications requiring real-time high-precision navigation.

Multi-star Multi-frequency Receiver

Centimeter-Level Positioning

Dual RTK For Yaw

Double Unit Switch

Multi-star Multi-Frequency High- Precision Positioning

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

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.

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

Use as a sky unit

Use as a rover unit
