# CUAV C-RTK2 GNSS Module (RTK/PPK)

The CUAV C-RTK2 receiver (opens new window) is a high-performance PPK/RTK positioning module created by CUAV for professional applications such as drone aerial surveying and mapping. It has a high-precision IMU and positioning module, and can reduce the number of required control points (opens new window) by more than to 80%. In addition to surveying/mapping, it is suitable for many other use-cases, including: agricultural plant protection and drone swarms.
