Trimble Alloy-NTrip problems
I have a Trimble Alloy that I use as a base, sometimes in a fixed location with internet access but sometimes in the field with a cell modem for access to the NTrip caster on board. It has always worked well.
Last week I decided to try it using an external radio, a Trimmark III to broadcast RTK corrections. Seemed to work OK, except I had it set for 4800 baud over the air rather than 9600, so it did not send all constellations over the air (rover was a new R10-2).
After that, it now only transmits empty NTrip packets over the network. I tried resetting it, re-installing the firmware (5.43), but nothing seems to help. As a test I put the R10-2 side by side, and had both of them configured to send RTCM3.2 to SNIP running on my desktop (internal network). Here are the packets the R10-2 was sending out:
And the Alloy:
after about 7 minutes, here is a comparison of the data flows (TS is the alloy)
As can be seen the R10-2 sent 800KB of data and the Alloy only 7 KB.
The reference position is accurate on ITRF to better than 1 cm in all three dimensions, so that is not an issue. I also tried CMRx, but same issue.
Has anyone else ever tried to send corrections out the serial port to a radio from the Alloy? It may have nothing at all to do with the fact that I hooked the TM3 up, but the last time I used it before that it worked fine. Maybe just a coincidence…
I didn’t try the radio again but maybe I will test that tonight
I need to take it to the dealer but just wanted to see if anyone else has this problem.
It does seem to be tracking OK, here is tracking summary from the header of a rinex 3 file for 24 hours…
