This resulted in a significant drop of the observations for the affected satellites in the IGS network. Trimble has finally published firmware 6.60 that fixes this deficiency. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Release notes: <a href="https://trl.trimble.com/dscgi/ds.py/Get/File-1084513/Release%20Notes%20FW%20Alloy%206.60%20-%20(August%202026).pdf">https://trl.trimble.com/dscgi/ds.py/Get/File-1084513/Release%20Notes%20FW%20Alloy%206.60%20-%20(August%202026).pdf</a><o:p></o:p></span></p><p class=MsoNormal>Firmware: <a href="https://trl.trimble.com/dscgi/ds.py/Get/File-1084484/alloy_titan_V660_V660.timg">https://trl.trimble.com/dscgi/ds.py/Get/File-1084484/alloy_titan_V660_V660.timg</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US>So far, only very few IGS stations have this latest firmware installed.
