Your Lefebure NTRIP Client shows changing between GPS mode and Float RTK intermittently. Usually this implies the Alpha+ RTK rover is occasionally receiving correct base station RTCM data. When it can correctly receive RTCM data and meeting some internal requirements, Float RTK is shown. When unable to receive correct RTCM data, GPS mode is then shown.
Please make sure you have stable Internet connection to the RTK base station service on your phone. After a short period, within 1 minute, should at least get stable RTK Float under open sky, if for some other reasons unable to get RTK Fix.
If you still have problem getting at least stable RTK Float, please send an email to email@example.com, we’ll provide access to our base station for testing. Although won’t be able to get RTK Fix due to too far distance, can at least cross compare if able to get stable RTK Fix, clarifying if it’s (1) Internet connection problem or (2) problem with your local government CORS.
