# Centimetre Accuracy

In order to get accuracy down to centimetre level, Real Time Kinematic (RTK) or Post Processing Kinematic (PPK) can be used with your mobile phone.

We encourages citizens to build up [their own RTK infrastructure](https://discuss.88.io/t/geo-survey-tools/239/4) in the communities.
