SatId 20959 GPS SVN32 should now be visible here in Seattle but I have no success seeing it with either a Thunderbolt, an Oncore VP, a Datum 2000, or an M12. True, the satellite is marked unhealthy so it is expected not to see it in the GUI or the timing solution.
However, I am also logging raw Motorola binary messages out of the M12, including the @@Ha status message which reports unhealthy as well as healthy satellites, I think. Still no SVN 32. I have a hunch. The M12 has a @@Am message to manage the "satellite ignore list". According to the manual this is a 4-byte (32-bit) field and thus it appears there is no way to set the ignore bit for any satellite with SVN > 31. Perhaps not a problem. But it suggests there may be internal 32-bit limitations, yes? Same thing for a Thunderbolt. There are a number of places in the TSIP user manual that talk about 32 SVN (i.e., 0 to 31, or 1 to 32) and no more. A similar 32-bit binary limitation as the M12, perhaps? I wonder if someone at Trimble or ex-Motorola could comment. My rash prediction is that no one is going to see SVN32 with an Oncore VP, M12, Thunderbolt, and maybe a few others. Then again, I wonder if things might magically improve in a week when they set it healthy. Note this is not a operational or performance problem, really. GPSDO did just fine before 32 SV and a receiver overlooking one or two high-numbered SV due a 32-bit receiver limitation isn't going to make a noticeable difference in the performance of a multichannel receiver or GPSDO. > Tom > > My Z3815A sees PRN 32 now albeit as unhealthy. > > Bruce Right, I concur!
