Were you receiving corrections? Looking at your screenshots, it looks like you have “average Fix” selected, but input corrections “off”. Your base will never set a base point with those conflicting settings.
If you are just testing, just use average single for collecting your base point. You don’t really care if it is super accurate for testing. The way you have it set, the base point is really suspect and that could confuse the drone.
In the field for a real project, then you can either receive corrections and collect an averaged fixed point. Set up on a known point and enter the coords manually, or average single and post process the data later.
No. But the base has to establish a point in order to send reasonable corrections to the Drone. The way you have it set, when you turn on the RS3 at your test site, it will not establish a point. It may just retain the last point that it had. “Input > off” and “average fix” will never happen. For testing, just change your “coordinate entry method” to “single”. Then whenever you turn on the receiver, it will average a position that will be reasonable for your test.
Again, if you are not receiving corrections to your base, you cannot use “average fix”. You must use “single”. And then, yes. You can post process that position through OPUS.
Pete. You really should spend some time reading Emlid’s docs. They are very good. Almost no one can casually read through them and be done. This stuff is very particular and it takes going over the information many times for it to sink in. For most of us anyway!
I having no success getting the Emlid caster configuration to work. I have the RS3 AND the Drone controller on their own internet connection with the RS3 using its own hotspot and the RC Pro controller using the cellular dongle and I’ve read all the docs but I’m not sure what I’m missing.
Yes, after figuring out that I had to turn off and turn everything back on, I finally connected with local trip. Although it seemed kind of feisty. The final frontier is Emili castor.
Are you able to connect your base to the mount point, and verify that you are “online” at castor.emlid.com?
If the base is verified and connected, but the RC Pro doesn’t connect, have you tried connecting the RC pro to your phone’s hotspot for internet instead of the 4G dongle?
No I have not been able to successfully connect the base to the caster service mount point. I did double check the credentials too. I made sure base and drone controller were connected to phone hotspot.
Dave, today I finally got Emlid Caster to work. It was a tedious matter of turning everything off and on till the drone connected. Both base and RC controller were connected to the RS3’s hotspot. Something about having to turn things off and on to get it to hook up. Maybe I’m missing the order of operations.
I’m glad to hear that the setup is eventually working fine. Still, let me jump in and share some additional thoughts that can help sort everything out.
Using either local NTRIP or Emlid Caster, one of the most important things is that the base position has to be determined. It’s a requirement for the correction stream. If you’re just testing the setup, let’s quickly use average SINGLE. As Dave also underlined, using average FIX requires receiving corrections while the averaging is done.
Then, in the case of local NTRIP, if the base and the drone controller are connected to the same network and you’ve added the credentials, you’re good to go. But please note that the base and the controller should be within a few meters to have a stable connection.
The Emlid Caster setup doesn’t require this short distance but a stable Internet connection for both devices instead. If this is given, and the Emlid Caster credentials are provided, the drone should be able to receive corrections.
I hope this helps. But feel free to raise any further questions, and we’ll make sure to help you out.
Thanks so much for the concise info, Kornel. I’m wondering one more thing as I try these configs. Will the accuracy be affects by how long the base logs raw data BEFORE I turn on the drone and fly? Does the drone have to be turned on the same amount of time as the base is logging? Is ten minute better than five before I fly or is it just the totally amount of time logging from start to end of mission?
With an iPhone make sure that “Allow Others to Join” and “Maximize Compatibility” are both on. I have been using my 14 Pro for a couple of years and it works great.
Regarding the logging, the most important thing is that the recorded raw data from the base and the drone overlap in time. If the base’s logs are longer, it won’t affect the results in any way. But please make sure that they’re at least as long as the drone’s logs.
