sklimkim Sorry for speaking English but I got here with the help of online translation ! I see you are using a SiRF receiver, me too ! Which one is it ? I have an old Globalsat BT-338 that I downgraded to FW 3.02 with Phase patch to be able to use it with RTKPost or maybe even RTKNavi. I tried to use your Kinematic2_MobileApp tool but I get no phase data although it does appear to be there when I log to raw with SiRFDemo. Am I doing somethin wrong? Thank you !
