Gregory,

It looks like you're into a whole bunch of bleeding edge pieces with this Alloy:

[744] teqc +all -O.sum . allo______201901192300A.tgd
? Error ? translation of 'allo______201901192300A.tgd' may have started with GPS week 2038 rather than 2036
         (try using '-week 2036' option)
! Notice ! unknown Trimble antenna type (Trimble .dat record 16)= '0S' in 'allo______201901192300A.tgd'
! Warning ! constellation ID 9 detected in 'allo______201901192300A.tgd'
.dat 27/0x57-6: unknown SV type= 9
! Notice ! 'allo______201901192300A.tgd' contains Beidou data w/ 'block type'= 2 'track type'= 8 of unknown type ... skipping
...

There's been testing on an Trimble Alloy here at UNAVCO, but I haven't seen any of this
on the data files from ours -- and we have been tracking Beidou SVs.

Is this by any chance tracking one or more IRNSS SVs?
