I took this off line because the below has a negative comment about
Lefebure's generally really good work. <br>
<br>
From what you say, you simply need a caster, in particular one that
will relay the serial serial off your uBlox to one or more clients.
Okay, we have a commercial tool (simple NTRIP os sNTRIP) with a
"free" mode that will do that I can send you, <u>but how will you
connect the cellular link to the "home-office pc" without a static
IP</u>? If you can overcome that (I know there are some sort
dynamic DNS solution to do this), got you covered and will send you
a released you can use as long as you provide me a bit feedback on
what you think is lacking with it. But is will easily do what you
need today. <br>
<br>
The Lefebure caster/server will not work because he has not updated
the code base for a numbed of years, and the thing leaks memory and
creates multiple threads until it locks up in an hour or so. [The
client code works fine] The last time I spoke to him was over a year
ago but at that time he had no interest in developing it further
(the source case is dot net and I think that he posts that as
well). The real beauty of that tool (and which then motivated what
we built here for the past two years) was that it combined the the
serial port part (the so-called NTRIP server) with the NTRIP caster
in to a small simple utility for a PC. Most GNSS device makers want
$1kUS for that feature alone. <br>

<pre wrap="">After some testing it seems that the RTKGPS+ does very good job if configured
properly.
I managed to achieve a instant fixed solution within 1-2 seconds using the
base and rover at the same spot. What makes the difference in a quick fixed
solution is the output rate of the receivers. I set it at 5Hz both at the
base and rover and it made a huge improvement in reacquisition time. Also I
have to turn off the Ionosphere and Troposphere correction otherwise I can't
get a fix.
The problem now I stuck at is how to configure the base (placed in a distant
location up to 1-2 km) to send the corrections via cell phone's internet and
then the rover receives the corrections via internet using a second mobile
phone.
>From what I have read (sorry I am not a expert) there is 3 parameters
involved.
A Ntrip server, a Ntrip Caster and a Ntrip Client.
I can't understand if the RTKGPS+ can act as a Ntrip Caster. If it can act
only as NTRIP server and client, I do need a NTRIP Caster which basically is
a home-office pc that runs a software (e.g. Lefebure Ntrip Caster) that
receives and sends the corrections to the rover. However I tried to
configure the Caster with no success. It must be something with the firewall
of my network.
Is there any other method so the base can transmit the corrections via the
internet of the cell phone? For example the TCP Client of the output
solution how can it be configured?
If anyone can enlighten me I will appreciate it.
Thanks!
