these apps any use?

any of these basic apps you can program your sections in such as we have a 21m sprayer, 4 sections outside 2 are 4.5m each inner 2 6m each just be handy if it told you which to switch as we have a few near parallel headlands that we probably over spray more than needed.

I use this at the moment seems to do the job http://machineryguideapp.com/en has section control etc.

how much is it and which one have you got? or just the app?
I often thought they could do it like this with an antenna for your phone to get good enough accuracy.

I fancy it for fert, spray and marking out with combi drill (nip round outside of field hard in hedge then go round following satnav say on 5th run in with just harrow no seed then you can use straightest edge to strikeout and your tramlines are in time. I do this at moment but use previous cultivation or ploughing to "judge" my start and stop)

I have the app on a Lenovo tablet and the submeter antenna/receiver which connect via Bluetooth to the tablet, I paid £136 for the software and £300 for the antenna back in 2015. I thought about upgrading to the Decimeter antenna /receiver last backend think it was around the £580 mark, exchange rate may alter that though.
They are open to suggestions when up dating the software so if you have an idea they will consider it.

Without wishing to pee in every bodies champagne but for the average grassland farmer a cheap tablet and a free app is perfectly capable of providing guidance for fert application,
and setting up reasonable bouts when cutting grass

I use Agri nav app on android phone. Got a quartz reciever but on my phone less accurate

agri nav is good, untill next year when it wants a reg fee. think it was $60 a year,, there are others out there.

Needs a bit of a survey to find the cheapest tablet with the best gps chip
Whilst the phones work well , it soon becomes apparent that bigger is better in this

Do you have a link to the decimetre antenna and receiver?

This is their products page

Have a look at this:

You have a facebook page with all pictures and videos. I would say it is affordable solution.

there is a new phone on the market with sub centimeter accuracy .. the nav game has just changed.
Why are the schools not teaching kids how to program these things.
We have had a 40 year gap since the BBC micro's taught school kids about programming and very
little since, untill arduino came along to ignite interest

Where is this magical device?

That's better than multiple frequency, multiple constellation RTK with the best antennas and survey grade kit known to man.

Xiaomi ,, seem to have announced new phone in last few days,, the first with chipset able to take advantage of latest galilao features,
hmm maybe sub centimeter is optimistic, seems more like 30 centimeters

Even though millions of users make use of GPS enabled services like Google Maps and Apple Maps for navigating, the GPS chips do not show accurate location. For instance, when you are driving on the highway, the navigation app can’t accurately tell whether you are on the highway or on the road next to it. This is because the accuracy of today’s GPS solutions works within a range of 3 to 5 meters. During the ongoing ION GNSS+ 2017 conference in Portland, Broadcom has announced that it is building a GPS chip that can accurately lock the location within 30 centimeters.

The existing GPS chips lock location by interacting with older GPS satellites that release L1 signal. The new L5 signal is sent out by newer GPS satellites. Broadcom has confirmed that it is its new GPS chip, the BCM4755, can work with the new type of GPS satellite can accurately detect the location of the user

I posted it in the other thread, but its a few deci-meters at best, so like 20 to 30cm in reality. Its definitely not capable of anything near sub-centimetre, unless it had help....from a correction source.

So thats where i first seen it, anyway its a fair step foreward for spreading fert on grassland and will certainly make letterboxing less hit and miss

Yes I won’t be rushing out to buy a new Xiaomi handset, but as the other big phone manufacturers roll out new models there’s a very good chance they will include dual frequency capable GNSS receiver chipsets on their higher end models.

That’s great news for end users as the basic accuracy, without any additional correction, has just been increased more than twenty-fold. The positioning error has gone down from around 5 to 10 metres to about 30cm. Better than having EGNOS!

There’s four more Galileo satellites that were launched last December that should finish commissioning sometime this month. So that will increase the number of working satellites from 15 to 19. Then there’s four more satellites being launched on 25 July. So by the end of this year fingers crossed the constellation ought to be about 90% complete, so coverage should be more or less on par with GPS and GLONASS.

Just reviving this thread.... have recently upgraded the fert spreader and keen to look into something along these lines... Iphone user here, have technology and apps moved on much in the last three years or are we still looking at an off the shelf specific GPS system?

Looked into it the other day, there's a few apps but without expensive gps receivers (£500) they were not great. Teejet center line are about 850 new all in job done or a ez guide at slightly more. I tried a few apps with a garmin receiver on ipad the other day alongside a teejet, wasn't up to the job for fert or spraying could be 3m off
