Looking for all the help I can get on this. Our survey department has two data collectors running Survey Pro. We have a single GPS setup that consists of a Leica GS14 and CS15. I am not a huge fan of the Leica Vivasmart software as I have used Survey Pro for the last 15 years or so. I came into a Trimble Juno T41 data collector for essentially no money. It has no software. I can get a really good price for Survey Pro with the GNSS module. The data collector has WWAN, Bluetooth, WiFi.
Our company uses the Leica as an RTK rover connecting to various base stations through the MaCORs system. Based on this, I would think I could pop a sim into the Juno T41running Survey Pro GNSS to get my RTK corrections.
My question is this. What would be the most cost efficient receiver compatible with Survey Pro? I know that running SurvCE would open more doors for hardware options, but I can't introduce a third data collection suite. I am looking for something that would connect to the Juno T41 over Bluetooth. I don't see a need for any bells and whistles on the receiver. The Juno T41 has the WWAN and 32GB of storage built in and an additional SD slot which I'll never need. I just need a no frills receiver that works with survey pro and delivers accurate results. I've seen that Spectra has the SP60 and SP80 models. The SP60 is in my price range, but the options available for it are what confuses me. I will only be using it to connect to MaCORS through the sim in the data collector. I know ashtech has some compatible models. Any advice is appreciated. Thanks

Isn't that what all of us want?

I lobbed it in and you hit it out of the park. Well played.
All seriousness, I just don't know enough about what differentiates receivers. Just need network RTK from my data collector.
We are all suffering from an overdose of complexification. Life used to be simple. NO BATTERIES. Except in the flashlight, and they were dead...
We used to do equipment maintenance. Take an oily rag, and wipe down the tape.
We used to go out, with a transit, and tape, and survey all day long, and come home, and swim in the river.
Now, we have 13 batteries, that need charged. And, if the GPS system glitches, we go home, or to the nearest wifi connection, and call tech support....
And, we don't have time to swim and fish.
I even think we need a basic course in geodesy, to get a survey license...

Seriously, Rtk GPS is like a symphonic orchestra. Many parts to be played, by many people, at the correct time.
It's hard enough, with one brand, without mixing brands!
Some of our modern engines, with overhead valves will destruct, if the timing belt breaks. The valves, while open, occupy the same space that the piston must pass through, while at, or near top dead center. All is fine, unless the valve train drive belt breaks. Its a toothed fiber belt. If the timing belt breaks, then the piston hit the valves that are in the open position, bending the valves, and sometimes breaking the pistons, and bending the rods.
To make rtk GPS work, the data at the base, and the data at the rover, must be combined, in real time, at the correct timing. And, you want a great dane, (one brand) to run in step with a beagle, (another brand).
It can be done, but you are asking for more than the manufacturers really want you to have.... In a general sense.
Some of them say that you can set up a rtn network, of brand "A", and any brand can hook up.... Although I am seeing it work, some brands make it harder than others.
I personally, don't want a rtn. Because although handy, none that I yet know of are running 5 Hz data.
Now, IF there were a rtn available here, I'd probably use it.... But having your own base, at 5 Hz is something to see.
I'm running a Trimble R2 with my T41, but I'm using Access. Not sure if the R2 is supported in Survey Pro.

I started looking at the R2 and I think it should work. The question I have is regarding the various options which can cause the price to jump about $8000 over the base model. Where I would be using network RTK I need to figure out which option would work. My T41 has a sim slot to connect to the RTK network. Does this mean I can get Trimble P/N R2-001-12. It is advertised as sub-foot, but would my T41 with a sim card connecting to a network RTK bring that down to survey grade? The RTK rover is about $12,000 and this model is $5,700. I can't find detailed data sheets for each individual model within the R2 family. Any help/advice is appreciated.
In order to get survey-grade you will have to get one of the four RTK versions of the R2. Those start at $9,995 for GPS only and go to $12,995 for GPS, GLONASS and UHF radio (receive only). The SIM card in the T41 will allow for cellular data to connect to a VRS network for use as a network rover. The optional UHF radio will allow for use as a traditional RTK rover. Not sure if survey pro supports the R2 though. Access does but Trimble doesn't sell a stand-alone license of Access to install on an existing T41. That's why I now own two T41s.
The Spectra Precision SP80 is built for Survey Pro and has as many of not more features than most of the other receivers on the market...plus, it is relatively cheap.
