GNSS chipset inside the Spectran V6 ECO

Hello,

If I'm not mistaken the GNSS chipset inside the Spectran V6 EVO is the same as in the Spectran V6, that is a u-blox NEO-M8T, assuming my statement is correct is it configured by u-blox factory defaults regarding GNSS constellations in use? if so, is there any way to alter this from end user point of view? I would like to enable GPS + Galileo + BeiDou, would it be possible?

Thanks and best regards

Yes but it is not possible to change any configurations so far. You might add this to a feature request.

Hi TC,

Before doing a feature request I would like to better understand how the position stamping works to better understand the side effects of such a configuration.

If I understood correctly from your response the u-blox factory default configuration is used, which in principle means that GPS+GLONASS are enabled which translates in to a maximum PVT output rate of 10Hz however if we enable 3 simultaneous constellations the maximum PVT output rate would be reduced to 4Hz so my question is are the PVTs (NMEA GGA?) used at the maximum rate for position stamping?

Please bear in mind that this post has been written without the actual u-blox documentation so it may contain wrong assumptions.

Thanks

The default is the concurrent reception of GPS and GLONASS offering the fastest cold start, highest accuracy and 4Hz chip set update rate.

The IQ stream gets the GNSS update within the ms range.

We might offer an adjustable setup soon e.g. to select different GNSS provider.

Hi TC,

I checked u-blox documentation and you are totally right for 2 concurrent GNSS constellations  the PVT output is 4 Hz, sorry about that.

Request made.

Thanks

Isaac
