Overview – For GNSS applications the RTK performance can be increased by using area correction parameters (in German: Flächen-Korrektur-Parameter FKP) information from reference station networks. The FKPs provide information about the distance dependent error components. For example, the Ger-man AdV organization, responsible for the operation of the SAPOS reference station networks, in-troduced FKPs as its standard technique to provide network information to any RTK rover.
For the use within SAPOS the AdV has defined and published linear FKPs and the corresponding algorithm. The parameters given in the RTCM message 59-FKP described in this document are con-forming to that definition, which is also summarized in chapter 2.1.
Chapter 2.2 describes the format of these FKPs in a special RTCM type 59 message.
