It sounds like you would like to get position data as a stream over time. You didn't explain what you are trying to do, and jumped to the conclusion that you need to use gpsbabel. Maybe you are right, but I'd say the odds are low. > I am sure it is a standard gps NMEA sentence file format, but... how to > successfully read it? You are sure because 1) you read the documentation and it says it is NMEA, and if so which version? 2) you looked at the data stream and it looks like NMEA? 3) something else? > PS: I bought the U-Blox EVK-M91 evaluation kit two weeks ago Is this the device you are trying to read? If so, that's very important information... For anyone else following along: https://content.u-blox.com/sites/default/files/EVK-M91_Userguide_%28UBX-19056858%29.pdf?hash=undefined See "5 Device Description" on page 10. This seems to be a u-blox M9 in a box. Note that this will speak u-blox binary, often written UBX. I don't think GPSBabel supports this. I would recommend that you examine the following gpsd (works well on u-blox F9, should be fine on M9) https://gpsd.io/ [Note that if you start down the gpsd path, and want to ask for help, make sure that 1) you are not using systemd and 2) you are using the latest release or git master. Requests for help with the version that shipped in some ancient long-term stable will not go well.] https://github.com/semuconsulting/PyGPSClient [I haven't tried this, but it looks interesting.] |
