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-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
Bought these to build a 7in 8S quad. The low kv is perfect for keeping the tip speed under Mach. These appear to be rebranded Emax EcoII, so decent quality. This quad is so powerful on 8S it's just silly. Happy Camper!
Good flier, handles the abuse a new flier like me has put it through
First prebuild from NBD. I swapped out the tracer RX for crossfire, initially had a no gyro flag on the AIO but was able to get it sorted with NBD support. Flying it is a good time and it’s held up well to some decent crashes. So far only thing(s) I’ve needed to replace has been a propeller and a M3x20 standoff. Took me too long to notice but the 2 aluminum pieces are for taking the O3 air unit from 25x25 mounting and making it 20x20.
