Does anyone know of a Trimble document that lists the recommended settings for receivers like the Alloy or R12? I am referring to static data collection that will be post processed in TBC or submitted to Centerpoint RTX or OPUS.
In the webUI the tracking page has a lot of possible constellations/frequencies/signals that could be set. Anytime I connect a data collector to the receiver to use as a rover, it turns off a lot of these signals. Since the receiver has a LOT of memory, I don't see the drawback to turning on everything. But I don't know for sure if any of these signals are detrimental since I cannot find any document saying what are the best practices.
Similarly, there are options under data logging like smooth pseudorange and smooth phase that I would like to know if it is wise to have that checked or not checked?
And, is there any info about IonoGuard? I am assuming that is only applicable at the base for real time surveys, but I am not sure. And should it only be turned on in high ionospheric activity conditions or left on?
If sending to OPUS make sure you have the logging rate at an intervals of 30 seconds. This can be set up in the survey style. You can log data to the receiver or data controller so make sure you don’t walk off with the data controller if logging to that. I prefer logging to receiver. Then download by jump drive or Bluetooth at the end of session. If sending to OPUS make sure you orient the receiver correctly I believe the R12 is the MMI man-machine interface so LED buttons face north. This is important for static especially opus as it now uses the absolute antenna calibration files. I wish I had those manuals but most of my stuff is boxed up still. I usually set my base doing rtk and logging at 15 epochs and decimate to 30 for opus. The ARP is the bottom of antenna mount not the quick release so pay attention on download etc. And when converting to rinex I usually have no issues with full constellation enabled the convert to rinex strips all the other stuff out anyway most of the time. I do see glitches sometimes when someone start it as a rover vs base going through the online thing to opus. But it’s been a couple months since I had to deal with any Trimble equipment. Hope this helps. @rover83 probaly is the guru on Trimble. He has helped me for sure.
You didn't really answer any of my questions 😉 but good information for someone new to collecting data for OPUS.
I feel that Trimble should be publishing this info on how to best configure the receiver, and what implications each setting has. Most people don't ever mess with any of this, and in fact I have found that many (most?) have never used the webUI. There is a help file, but it doesn't go into detail on some of this stuff.
For example, here is the tracking page...
The help file does have some recommendations for GPS and GLONASS, but no recommendations for Galileo or Beidou. And, the options shown as recommended do not match the drop down box, probably indicating that the help has not been updated with new versions of firmware.
Yeah so once my receiver is set up I don’t have to go into the receiver to configure things. I use the data collector and set it up. Like I said I turn everything on in the survey style because I am usually having rtk at same time collecting for opus. Trimble . Com and go to the r12 page I believe at the very bottom you can get to the manuals and settings guides. There is one setting in the receiver that can make it frustrating. I can’t think of it now. But it will cause multiple static files to be created if not set correctly on longer occupation times. My crews usually being on a site for several days have a minimum of 4 hrs and wanted one consecutive file vs multiple. There was a receiver firmware version that also caused that issue.
To answer the question. It is irrelevant of what constellation types you choose or do not choose besides gps itself. Because if you convert to rinex it will strip the others out depending on rinex version. I keep everything on and go that route is all. I believe opus might be close are already good on some of the constellations being processed but I can’t confirm that yet
Trimble vendors have info on how to configure receivers, which is how Trimble sells. If you are sending only to OPUS, it only use US satellites where Trimble RTX post processing can use all 4 constellations.
I was digging into these a few weeks ago myself and really could not find any good reference info at all. Kind of amazing that they provide all the available options without much info to help you actually use them.
