[time-nuts] Trimble Resolution T firmware

[GandalfG8 at aol.com]

In January 2010 Trimble made firmware updates available for the  Resolution 
T as well as for several other GPS modules to accomodate some changes  to 
the GPS signal structure.
 
The upgrade firmware provided for the Resolution T was version 1.17 and  
this is still the version currently available from Trimble's Resolution T  
product page.
 
However, when testing some GPS modules today I found  a Resolution T with a 
manufacturing date of 2007  but containing firmware version 1.20 of 21st 
April 2010, so  it's obviously been updated, but I've not been able to find 
any  reference anywhere online to a version greater than 1.17.
 
Does anybody have any information please as to what might be  different in 
1.20 and/or have any information as to whether or not Trimble  ever makes 
firmware updates publicly available unless obliged to  do so because of 
obvious significant operating  problems?
 
Regards
