MADOT changed their IP address for RTK Connection to Massachusetts NTRIP (MaCORS) a year or so ago. I just recently fired up my RS2+ since then with the new MaCORS connection data according to E38 Solutions:
I am also using a new phone as my mobile hotspot connection, Emlid flow app version 12.1 I believe. Firmware version on RS2+ is updated to version 32.2
I have signal from 39 satellites, and I’m probably not more than 5 miles from a MaCORS base station, yet I keep bouncing back and forth from “waiting for corrections” and “receiving corrections”. I’m perpetually in a “single” position. Can’t even get a “float” signal with no hope for a “fix”. Anybody else having these issues or know what the fix for it is?
Everything worked fine with my old android phone as the mobile hotspot connection and old MaCORS IP address, which admittedly was over a year ago. The Emlid receiver sat in its case on a shelf the entire time until recently and haven’t been able to do anything with it except update the firmware.
What kind of phone are you using now? Have you tried the Bluetooth connection to the device? We have seen some trouble with Google Pixels and bluetooth and iPhones if hotspot Maximize Compatibility isn’t turned on.
I did try using my home wi-fi once with the same results. I’ll try again or the heck of it. MACORS is the only service in my area unfortunately. A friend’s Leica GS18 works fine on the service, while i recently met another engineer who has my same issue with his Trimble GPS.
Got a Samsung Galaxy A35. I did try the bluetooth connection. I know it successfully connected cause I could make the LEDs blink and restart the sensor via Emlid Flow, same results.
@colemanhill, since the Reach is able to receive corrections, it seems that the setup is working correctly. The issue might be related either to the internet connection or the NTRIP service. However, since we already tried using a different hotspot, and that didn’t resolve the issue, we can likely rule out the internet connection.
Given that another GNSS receiver is also experiencing issues with the same NTRIP service, it’s likely that the issue stems from the service itself. I recommend contacting the NTRIP provider to check if there are any known issues on their end.
I don’t know if its connected to my issue, but i noticed while messing with it today, the Emlid Flow app shows 39 satellites in view in the top right of the screen where is says single, float, or fix. But in the status overview window, under the signal to noise graph satellites in view is identical. Farther down said window under “corrections”, below Channel - NTRIP it shows sattelites in view being zero. Is that proof of there being an issue with the NTRIP service, or should that reflect the same # of satellites as above regardless.
Are you also operating out of Massachusetts, or another locale and just suffering through same issues. Frustrating as hell when government “fixes” what ain’t broken.
@colemanhill The top number represents the satellite count from the device, which in this case is the rover. The bottom number near the correction status indicates the satellite view count from the base, which in this case is the base provided by the NTRIP service. It can be due to an issue with the connection on the NTRIP service or an issue with the base.
