Hello
Is there anyone on this forum who flies an eBee RTK connected to either a Trimble R8 or R10 base reciever and willing to share your settings? I previously was successful connecting a Spectra PM800 and a CHC X90 to an eBee for RTK corrections. But the Trimble receivers are proving to be very difficult to get a reliable correction signal from the senseFly radio modem.
Not even senseFly or RDO has been able to find a solution.
Any help is much appreciated.
Your post is the first one I have seen on this forum, about that model and brand. There have been a number of posts about Pix4d, and about the Phantom quad copter, in various flavors.
So, evidently, there is either a silent user group, or they ain't talkin.

What kind of radio(s) on the ground base? Chances are that if you were using a Pacific Crest radio with the Spectra and CHC receivers it was transmitting the default PacCrest data format, whereas a Trimble base that's set up to work with Trimble rovers is probably transmitting a legacy TrimTalk format.
According to SenseFly's web site, the GNSS receiver on the eBee RTK is looking for RTCM 2.xx or 3.xx corrections. So a Trimble base would need to be:
- Configured to output RTCM
- Connected to a radio (presumably PacCrest) using the generic radio settings and transmitting at a baud rate that the eBee RTK is set up to receive
They're real good about saying how easy their "magic box" software makes everything...
The basic operation is the GNSS antenna streams RTCM to a laptop via serial cable. The eMotion software which controls the eBee processes the RTCM and sends corrections through the senseFly 2.4 GHz radio which is plugged into the laptop. So no radio is needed with the receiver, internal or external.
I've configured the Trimble to stream RTCM and matched baud rates on the antenna, COM port, and software.
The problem I'm having is an unreliable and intermittent connection where the RTK mode will not stay fixed. Back and forth between fix and float.
Isn't this a question their customer support should hand and in short fasion? I mean you paid umpteen thousand dollars, right?

I'd suggest making sure that L2C, L5, Galileo, and Beidou are all unchecked in the Trimble Survey Style. Beyond that, I would experiment with different RTCM versions to see if there's one that works better. Also make sure the baud rates are fast enough to transmit RTCM without exceeding the duty cycle.
I just looked at the RTCM options in Access and I see that only RTCM 3.2 supports all those multi-constellation signals; I'd avoid that. I'd probably try RTCM 2.3 first.
The only other suggestion I can make is since you're sending the data out to a PC use Custom Radio under Base Data Link and make sure the parity matches - I'd assume None is the default in the software but you need to check. You probably want CTS unchecked but I'd try it both ways.
Jeff S - yes you would think senseFly would have a solution. They've put in the effort, but unfortunately nothing they've recommended has worked. The dealer we bought it from is also a Topcon dealer, so the haven't been much help with our Trimble equipment.
Lee D - thanks for those settings tips. I'll give those a try next time I have the opportunity.
I know the thread is a little old, but did you ever get the R10 working with the Ebee??ÿ
Thanks!
