Anyone using this service? Curious if it makes a big difference on base/rover range and speed of fixes? ?ÿThinking about checking out the 6 month trial but thought I??d ask here first.
Duel base line never caught on, maybe duel NRTK will. Bluetooth waves, GNSS waves, cell phone waves, Ntrip waves and internet waves, surf's up.?ÿ?ÿ

Looks like it's just an NTRIP service for base/rover. Latency will affect speed of fixes, but nowhere near as much as the RTK engine itself, and the number of satellites/frequencies received by both base and rover.
Sure, range will increase with cellular, but baselines are still subject to quality degradation as that range increases. This, again, will vary depending on satellites/frequencies observed by base and rover, plus atmospheric conditions. You can get better precisions from longer baselines than in the past, but as always it depends.
There are pros and cons for both UHF and cellular. Whether one is better than the other generally depends on working conditions.
If you always work in areas with good cell coverage, cellular is generally the way to go. But if you tend to work in areas with poor coverage, or in rough terrain, UHF will give you the most flexibility, allow you to optimize your project setup and cut down on time spent spinning your wheels trying to make things work.
Having an external radio as a backup to cell is the ultimate. If cellular is not working, and you save a single day of work by switching over, it's already paid for itself.

I like running dual bases, but it does take a fair amount of planning and logistics, plus a full extra base setup. I remember it was mostly for setting monuments with high precision. (Set post mon, stabilize, stake out from one base, mark cap with pencil, switch bases, stake out and mark again, split the difference, punch cap, then switch from RTK to static and observe for two short sessions.)
What range do you normally get? I have noticed the ability to fix with VRS, but not with B/R in one particular situation. ?ÿAbout 2,000?? from base, only about 20?? difference in elev. ?ÿWasn??t sure if this had something to do with internal radios? ?ÿI??ve also noticed B/R works a lot better early-miday, not so much late afternoon. ?ÿThis is in more challenging environments, not open fields.?ÿ

The description of Listen-Listen makes it seem like a cloud ntrip system. Not sure the benefit to that.?ÿ
I would love a dual base where you could hook up to a network, get a fix, then calibrate your base using that fix, check into some control, and then have software that monitored your precision with two baselines, and also could switch in and out depending on coverage and such.
Carlson used to offer a version of this with the ALTAS system, I thought. I thought they called it Surefix.
@dmyhill?ÿ ?ÿAshtech had a Duel Base once. I thought it might work for me, but a year later it was off the market.?ÿ Getting the radio out of the system has to make it faster and less cumbersome. I just wonder if you could use the nearest free WiFi? if so, by next year you could see a dozen GNSS units setup around the neighborhood Starbucks.
