If you put in coordinates 100 m beside the actual, in the Base station then you might only get Dgps or single.
even 1m accuracy from base is enough to get RTK, as long you enter an almost correct position (as fixed position) in base.(BUT then DO NOT move your base antenna) or next year AB line will be wrong.
AND remember to use correct . or , Some languages like mine, do it different but it must be like this 41.40338, 2.17403 41 a dot 40338 then a comma and 2 dot 17403
Depending on which format you have to input the coordinates, this link might be useful: GPS coordinate converter
I know because my skytraQ Base output another format than what was needed in rtk2go NTRIP caster using STRSVR ver.demo5
(my rover is a F9P)
Hi every body
I have a base that seems ok : get Rtcm3 sentences +glonass ;beido,gps .
the baudrate , 1 hz , set to approx coordinate writen the right way ( specialist in GIS and datum wgs84 , utm … )
The packet console give me hope that I am near the end of the tunnel for the base ( ardusimple rtk2b with F9p + Xbee for radio communication to the rover ) I do not use Ntrip ,only radio communication base-rover .
everything is threw USB
So I re verified the FW of the rover 1.13 , the config ( from Andreas ) and all the details I read in this thread .baudrate ,herz at 10 , save the right way -i hope !
Plug U-center to the Rover and read the packet console : got GPS fix plus the GGA and VTG sentences . BUT when I plug the rover to AGOPEN got GPS single
I let it for 2 hours with no results
The coordinates of the base are 10m approx
I cannot understand why the ASimple pair of preconfigured base + rover I bought worked perfectly with agopen within seconds ( 1.12 FW +1hz base +1hz rover . More ,I did not set the lat,long coordinates
I am desperate but confident that you could help
bruno
I know it is a different F9P but came to think of the problems I had with getting bluetooth working on mine.
Could be it is a setting like that you need to change?
My problem was that VTG was only selected for USB.
On the base do you see the GPS → XBEE LED flashing?
On the rover, do you see the XBEE → GPS LED flashing?
When you swap the rover from u-center to AOG, is this in the same location with same radio coverage? Did you disable all messages except GGA and VTG going to AOG?
In u-center you may check IO. UBX/MON/IO should show the traffic on the several interfaces.
UBX/MON/TXBUF could show eventual buffer overflow issues.
Are you using ardusimple config on the base? On the rover with the aortner config using the radio I think you need to enable rtcm3 on (cfg-uart2inprot)
With aortner base enable rtcm on cfg-msgout uart2 and on cfg-uart2outprot
I’m not by my computer with my configuration files but I think that’s what I did.
thanks for your responses to SjaakA ,Larsvest and Tfriesen and Commonrail who is already 2022 !
I shall try each of your advices
Few answers: base and rover have Ortner files
When I swap the rover from Ucenter to Aog , I do not move the tractor
all the messages I see in Aog are GGA and VTG :all other are disabled by the Ortner Conf
I will also see on the rover : anable Rtcm3
and on the base ( with Ortner conf ) enable Rtcm
I am a nerd on theses sentences
also have a try with Tony base + rover files
bruno
On the base do you see the GPS → XBEE LED flashing?
On the rover, do you see the XBEE → GPS LED flashing?
just the opposite !!!
for the two of them :perhaps a key to solution ?
On IO window there is nothing quite interesting :
Txbuf :no overflow
to Friesen , Have looked to RTCM config
rover : rtcm3x is enabled
base : rtcm2x is enabled seems Ortner’s config ok
Again : the base on power and the rover plugged to U center got
" GPS fix : 3D "
and gps single when Rover plugged to AOG
as far as I have seen , could not re re verify wether or not all NMEA messages are disabled ; all I see in Package-view are GGA and VTG sentences
Could you give me the path to follow to disable all nmea message except GGA and VTG ; even if I think it is already done with Ortner’s config
In U-Centre the base should show “3D” fix when survey has not finished, when its finished and locked in it will show “TIME”
If you look in messages view, scrow down to NAV - SVIN (Survey In) you can see the progress. (With my setup when > 300sec and < 2.5m survey is finished)
or
Open note pad, save two blank text files as bruno base & bruno rover. Then open u centre and transfer config files from rover and base to these files. Post them here and we can tell you excaty what is wrong in the files.
high Tony
I get 3D fix , I don’t get TIME perhaps linked with my approximative Lat/Long
did not try yet the two config files : tomorrow
I send the bruno base and bruno rover asap :good idea
good day
Tony
got mad with ucenter :couldn’t install on my surface pro4 ( some dll missing )
but got a old v20.0 on a very old windows PC !!!
so I join here some files : Andreas’s files
base + rover
and a copy of the sentences I get on U center plugged to the ardusimple base with ortner-base file . the firmware is the 1.13 one from ucenter
The next step is the use of Tonybase and tonyrover ,but can you give me your opinion on this setup before I re configure everything
thanks

The base file of Andreas’s is not made for radios, it is used for USB only. (Connecting to computer / ntrip)
Load the config files through U-Centre- Tools, Reciver Configaration, Transfer File > GNSS.
Click - View, Configaration View, 3rd line down CFG (configaration), highlight all 4 memorary locations (hold Ctrl when clicking to highlight), click send in bottom left.
Then you can open View, Messages and see all the info messages
ok Tony
I will do that
Pity Andreas did not explain that in detail :lost time with
I was wondering why the "factory " configuration was working perfectly and not the conf I found on the forum
Know now why I only get GPS single
have a good day
bruno
wonderful
got rtk fix in seconds !
Now two short questions
can I move the base in each field I have cause they are distants each others : more or less 20km
can I add two more rovers to the base :if it is possible ,it would be great !
many thanks anyway
bruno
Seems you are using radio from the base to the rover. You can have an infinite number of rovers as long as they all work within a decent distance from the base.
You can move your base but ideally you should have an accurately repeatable installation position and you should use the same surveyed position at that particular base site. Obviously with a single base, rovers would need to be at that base area if the base does not cover all your fields from one location. NTRIP would have solved the range issue if you have any decent cellular coverage but better to consider that later, take one step at a time.
ok
I consider Ntrip for next winter !
For the base moving ,if I understand correctly , Better if I use the same position each time ,and with an high accuracy :better than 1 meter
Otherwise , a completely new different position will require 1 hour or two for UBlox to get the satellite ephemeride as I did yesterday for my first try
Is it so ?
bruno
A bit of a matter of opinion but I’d say the base should be placed to the same spot with an accuracy of 1 cm or less. Otherwise you lose a lot of the RTK benefits.
The same if you do a self survey of only a couple of hours. The self survey accuracy is OK if you always use the same coordinates at the same spot.
You could have a few spots where you want to put the base and survey them in over winter, then when you put the base back there you could enter those coordinate and use it with great accuracy
