Poor signal with egnos on EZ500

[Farmer Fin]

Hi. Spraying this week and out ez500 keeps losing signal. It’s a Trimble antenna. It always loses signal in certain fields behind building and near trees but this week it’s been going in the centre of fields. It’s been a bit cloudy but not bad. Is this normal? Any ways of boosting or doing something to the antenna?

You mean it loses GPS signal, not (only) the EGNOS correction signal?

Sounds like an antenna cable issue?

Is the GPS not egnos? Does it connect to more satellites?

You don't mention details about your receiver which is why I assume it is a standard EGNOS capable GPS receiver.

The receiver probably supports GPS and GLONASS satellites but it needs a correction signal to achieve any decent pass-to-pass accuracy. EGNOS is this correction signal, it comes from a separate geostationary satellite. EGNOS just does not cover GLONASS satellites (so far), so you will be using GPS birds only.

In order to work properly, your receiver needs to see a sufficient number of GPS satellites and the EGNOS satellite. The EGNOS signal comes from south, from a low elevation satellite. So you have to have a good view towards south.

Our EZ500 lost EGNOS last year, we've been spreading fert on uncorrected GPS only ever since. Not ideal, but seems to work fine without striping on 24m.

I have a feeling it needs a software update, not sure who would put the last available update on for me though. Doesn't matter where I am, it won't pick up EGNOS and that's with an AG15 antenna

There was an update 18months ago. It was easy. There was a link in here somewhere and i soil essentials website. You also had to change some of the egnos satellites.

How much does Egnos signal cost?

Not as though it's for free.

I think it’s the gps. The instructions mention gps limits. Do you know what the values should be?

thanks Found the thread, soil essentials link doesn't work though... I found a 2018 update, but has anything changed since then?

I think that will be it. It came out Autumn 18 if I remember rightly.

 

[Northern farmer]

Right, files appear to have the date 4.10.2018.

Hi ... I've just checked the links for this and worked fine for me

EGNOS Broadcast update - SoilEssentials

AS of 30th of August 2018 there have been changes to the way the EGNOS correction signal is broadcast across Europe. For those customers who are experiencing lack of EGNOS signal on EZ-Guide 250 and 500 displays it is recommended to install a new firmware version onto your display. Following…

Nothing has changed since.
