Whilst downloading some information from Trimble's support pages today I
discovered, only two years late:-), that in January 2010 Trimble released
firmware upgrades for the Acutime Gold, Mini-T, Resolution T, Thunderbolt E,
and no doubt other GPS units too.
Trimble states in each case.....
"This firmware version was published to correct the signal tracking outage
every 12.5
minutes due to the change in the GPS signal structure by the DoD."
No firmware update seems to be available for the original Thunderbolt, nor
for other earlier units, which probably isn't too surprising but I don't
recall anyway ever noticing periodic dropouts of this nature when monitoring
Thunderbolts.
Does anybody have any experience of this ?
