gps - Enabling 10 Hz sampling rate in Ublox modules -

i'm using ublox neo-m8n-0-01 gnss module. module supports 5hz gps+glonass , 10 hz gps only.

however, when seek alter sampling rate (via ubx-cfg-rate in messages view) can increment 5 hz (measurement period = 200ms). value below 200ms impossible (changes box pink).

it happens if produce nmea message gxgga.

the way made gps via ubx-cfg-gnss

has encountered issue?

thanks in advance

you don't how setting rate going description i'm assuming using ublox u-center software.

there simple explanation issue , simple solution: software has bug in (or wasn't updated match final specification of part).

the solution not utilize u-center, it's pc software that's complaining not receiver. receiver doesn't care spec sheet says, seek it's best run @ whatever rate request.

sending commands straight i've managed reliable 10hz gps+glonass. there occasional missing point of time keeps up.

running gps can faster 10hz. if play settings , restrict 8 channels 18-19hz reliable. unfortunately 20hz pushing far, end getting positions @ 10hz.

obviously when running @ these update rates create sure baud rate high plenty cope requested messages , rate.
