GALILEO instead of GPS Receiver

Fri Dec 16, 2016 8:22 am

Hello,
Since 15.12.2016 the positional satellite system Galileo is in operation offering a finer resolution and is not controlled by the military.
I would like to see recommended receivers and tests for Galileo receivers please.

Found this on Ebay - don't seem to be many available yet.

Only thing to suggest, buy one, try it out.

Seems to be a dearth of information about Galileo capable receivers. There also seems to be a bit of sabre rattling by patent holders, so maybe that's the catch.

I notice the Ebay unit says that Galileo is "under construction" - so probably needs a future firmware update to actually do Galileo. Or not? Any Galileo experts on the forum?

Not an expert on GPS, but for uBlox based systems this will probably be a useful read -

Galileo has only just been turned on properly, this week I believe! So not really surprising there are not too many receivers about. Supposed to be very accurate. 1cm IIRC.

1cm accuracy will be encrypted (paid for) service, public service is 1m accuracy I believe.

There is supposed to be interoperability with the US GPS system, but this will depend on firmware / software supporting both systems. It's also worth noting that GNSS (Galileo) is only in IOC (Initial Operating Capability) with around half the planned satellites in orbit, so coverage / accuracy may be poor until all 30 are launched.

Thanks Gordon, I did not know that....I'll need to get much more information. 1 Metre is fine with me...I wonder what the 1cm
encrypted would cost...
I had assumed that ESA would have contacted makers like "tom tom" etc with details of Galileo.

Merry Christmas

I just bought the same receiver on Amazon.
It was also said as ready for Galileo.

But in fact I discovered that it was impossible to work.

Tracing the NMEA messages I found :
$GNTXT,01,01,02,u-blox AG - www.u-blox.com*4E
$GNTXT,01,01,02,HW UBX-M80xx 00080000 *43
$GNTXT,01,01,02,ROM CORE 2.01 (75331) Oct 29 2013 13:28:17*4A
$GNTXT,01,01,02,PROTVER 15.00*01
$GNTXT,01,01,02,GNSS OTP: GPS GLO, SEL: GPS GLO*67
$GNTXT,01,01,02,ANTSUPERV=AC SD PDoS SR*3E
$GNTXT,01,01,02,ANTSTATUS=OK*25
$GNTXT,01,01,02,LLC FFFFFFFF-FFFFFFED-FFFFFFFF-FFFFFFFF-FFFFFFF9*4E

It means that the receiver has only ROM memory not FLASH
and the firmware version is old 2.01.

The firmware version with a full support for Galileo is 3.01

If you trace your receiver and see a FLASH CORE you can update the firmware with the software u-center from the u-box site.
