DriveLuxe 51 updates (and all Drivexxx x1 devices!) Now they see Galileo sats

 

I don't think this has been reported yet. The DriveLuxe 51 has a couple of updates:

Software version 6.00 March 27, 2019:
Change History
Changes made from version 4.40 to 6.00:
-Added support for the new Garmin BC 40 Wireless Backup Camera.
-Enabled Galileo satellite support.
-Improved routing calculations.
-Improved the reliability of connections to Bluetooth devices.
-Fixed an issue that caused some spoken words to be mispronounced.
-Fixed an issue that could cause incorrect route calculations when using maps of Southeast Asia.
-Improved software stability.

DriveLuxe 51 Language Text software version 2.00 March 27, 2019
Change History
Changes made from version 1.90 to 2.00:
-Various translation updates.

[Later] Thanks to alandb for reporting that updates are available for all Drivexxx x1 devices to include Galileo support! I've revised the thread's Subject so that others will know of the update.

Galileo

This is a surprise. When I bought my used DriveLuxe 51 on eBay, I never thought it'd be a Galileo-compatible device. But it is!

Agree.

Yes, that is quite a surprise for a device introduced in early 2017. Garmin apparently used a premium chipset that had the Galileo support. It is great that Garmin enabled the capability through a software update.

Edit: It appears that there are software updates for the entire 2017 Drive x1 series (including the Drive, DriveSmart, DriveAssist and DriveLuxe models) and all of them include the enabled Galileo support.

The DriveSmart updates were announced a little while ago, I remember asking questions about the Galileo part of the update, hadn't heard of it before.

Since the update I've been checking what satelites my DS61 is connected to and it averages 4 Galileo to 5 GPS.

On the screen where you see the scattered satellites I also see the sun & moon, which are obvious, what about the circled dot, is that where I am? (the photo is pre update)

Thanks for your recollection.

The red dot is your GPS's last known direction of travel (east in your photo, assuming the sat display is North Up).

Thanks for the tip. I just did the update.

It shows that Garmin is a quality product. The demise of the road GPS has been greatly exaggerated. No smartphone can come close to the GPS hardware and software in the Garmin Driveluxe 51.

How about this?

CraigW, here's a screenshot with both, sometimes when I open this screen the Galileo satellites show as hollowed bars when the screen first opens, then a minute or so later go solid, (keeping the same heights) any reasoning for that?

Satellite screen

With the outlined versus solid bars, I have assumed the outlined bar meaning that the device knows that that satellite should be seen, and that the solid bar meaning that it is actually receiving data from the satellite.

But I am sure someone here with more knowledge will be able to enlighten us.

.. why the different correct heights, meaning when they fill in the strength is the same as before they filled in.

thanks.

Ah, good question. Here's a guess or two. The individual bar heights could be:

1) based on signal strength of each satellite's RF transmission but before your device has included the satellite data into a positioning aid, and

2) based on each satellite's expected location (directly above, near or at the horizon, etc.) from your device's stored almanac assuming it's current and the device hasn't been powered up at a vastly different location than where it was last used.

I lean towards #1 although #3 (None of the Above) must also be considered. wink

Bar Height is Signal

Bar Height is Signal Strength.

I know that, I used the terms interchangeably.

The question is why the bars sometime look hollow as in my screenshot above, and once they fill in, the height, aka strength, remains the same.

Hollowed out could mean they haven't been found yet, filling in once found, but if that's the case how is the unit correctly guessing what the strength/height will be.

It's not important, just something I was wondering.

My understanding ...

My understanding is that a hollow bar indicates your GPS receiver can
"see" that satellite (in other words it is receiving a signal from it), but has not yet determined its exact location in the orbit and is not yet "locked on" to it for position calculations. GPS satellites send very basic timing and orbital information. For a single satellite, this received data could put the satellite in more than one location within its orbit, so the GPS receiver must do mathematical calculations in relation to the signals received from other satellites to determine the exact position of the given satellite within its orbit. That is why it takes at least 4 locked in satellites to determine your position on earth. Once it figures out the exact orbital location for the satellite, it "locks in" (uses it in its positioning calculations) and fills in the bar on the signal chart. I am sure this explanation is over simplified and probably technically flawed, but it is my limited understanding of how the GPS system works.

Hollow=I see you. Solid=I'm

Hollow=I see you.
Solid=I'm locked on.

Thanks alandb, sounds plausible to me.

10 Foot Accuracy

I am getting 10ft consistently with the DriveSmart 61 in my office. Never think to check it when it's in my car. It is showing 5 to 7 regular satellites locked on and 4-5 Galileo.

My DriveLuxe 50, running beside the 61 gets 24ft accuracy.

GPS Position Accuracy

Use caution when using position accuracy (EPE) readings. The number is an indication of precision or statistical level of confidence, not overall accuracy.

An interesting but somewhat technical article on the subject:

https://interpine.nz/gps-accuracy-estimate-epe-what-is-it/

While lower numbers are better, they are not a reliable indication of distance from an actual point on the face of the earth.

I was getting "10 foot" before the addition of Galileo, still get the 10 foot number so I'm not sure how the addition helps, but more (satellites) is better right. Of course I get all kinds of numbers still but the 10 foot did happen prior to the update as well.

So in the real world..

for those that have used Galileo enabled and non-Galileo units are we talking about like 10 feet better accuracy? Curious if they work better in areas where there are tall buildings like downtown area of major city where you're surrounded by tall buildings?

I would like to know as

I would like to know as well, my etrex 20 get within about 14 feet with good clear conditions but around tall buildings not so well

The last time I ever saw

The last time I ever saw better than 10 ft accuracy was with my old Nuvi 760 with the external antenna connected on top of the car. I remember seeing 5 ft, several times. But that's been a long time ago and Garmin stopped putting the external antenna jack on newer models.
