Good morning companions.
Has anyone a guide to configuring SimpleRTK2B to work with NTRIP?
Note: my board is a SimpleRTK2B V3

Dear topocomputer,
There’s no need to configure for NTRIP, you need a software that is able to connect to NTRIP caster and send RTCM corrections to simpleRTK2B. You will find a tutorial here: https://www.ardusimple.com/simplertk2b-performance-in-standalone-mode-and-ntrip-corrections/

Good day. Thanks for your quick response. I know what the procedure is to connect to an NTRIP server and get fixes. The thing is, I get “RTK float or Fix” status for just a few minutes and then it drops to “DGNSS”. I’m using the updated configuration file for “Rover” downloaded from the ardusimple website. So my question is aimed at whether this file, which I imagine is for Base-Rover configuration, is also valid to obtain NTRIP corrections or from the configuration offered by the file, you have to modify some parameters to work with NTRIP.

Buen día. Gracias por su pronta respuesta. Yo sé cuál es el procedimiento para conectarse a un servidor NTRIP y obtener correcciones. El caso es que obtengo estado “RTK float o Fix” solo algunos minutos y luego cae a “DGNSS”. Estoy utlizando el archivo de configuración actualizado para “Rover” descargado de la pagina de ardusimple. Entonces mi pregunta va encaminada a si dicho archivo, que me imagino es para configuración Base-Rover, es también válido para obtener correcciones NTRIP o a partir de la configuración que ofrece el archivo, hay que modificar algunos parámetros para trabajar con NTRIP.

1. Is it an exact number of minutes when it falls to DGNSS? Might be that the server is kicking you out because you are not sending GGA message?
2. What is the distance to the NTRIP caster. After 35km it is difficult to keep RTK fixes.
3. Do you have good signals? Are you in urban enviornment between very tall buildings? If you don’t move the antenna for a couple of minutes does it improve?

1. Voy a verificar la cantidad de minutos a ver si es exacta, y ver si tengo habilitados NMEA GGA.
2. El lanzador NTRIP está a 9 kilómetros. Por ahí no es el problema.
3. Estoy situado en un segundo piso y tengo la antena en una ventana con vista amplia del horizonte.

3. centimeter-level RTK only works with complete visibility of the sky. If your antenna is only seeing half of the sky because it’s at the window of a building, performance will not be as per datasheet.
