GPS configuration

[sashoks34]

Hi,
I have Ublox VK16u6 GPS. It's sending in NMEA format, 1 Hz , 57600 bps.
On the ublox software (u-center) everything looks stable and correct, but on the MWConf i also has FIX 6 sats, same Lat and Lon, but the altitude and speed are very unstable (idle, ground) and changing 10-20 m.
Is something wrong with my GPS settings in config.h ?
Can it be the problem of the expected refresh rate ?
P.S. MW 2.4

Thanks.

What about your configuration?

[stronnag]

GPS alt and speed are unlikely to be reliable, especially when static. Really, you should be using ublox mode and 5hz if you want to do nav.

Ok, so i should set it to UBLOX protocol at config.h ant in the GPS.
Is there some configuration tutorial regarding setting special for MW parameters in the GPS ?

Other than the comments in config.h, none that I'm aware of. MW will send its own configuration to the device, so it is not necessary to pre-configure it. My two Neo 6m have never been configured (as ucentre is, afaik, legacy OS only), yet they work fine in MW and Cleanflight, ublox mode, 57600 baud.

Thank you stronnag.
I'm asking that because i found step by step instruction of configuring gps for megapitate. So i though that i could findhere ssomething like this.
In this forum i found only some posts about configuration file, but not something clear.
I'll try to understand from the code.
