<p>Hello all!<br>
</p>
<p><br>
</p>
<p>From DOY 045 (15 Feb 2016) we have system failure in NVSK (Novosibirsk, Russia) receiver's date - he say on screen about current date as 5 July 1996 and so on. As we think, this is a bug in firmware, affected only memory for date, which was full in 1024
GPS weeks and setting at zero (July 1996 is date that receiver was made) now. We hope, this is not affect receiver's precise time.<br>
</p>
<p><br>
</p>
<p>As write many russian geodesists on some forums, this failure affected all receivers, older than 2011: Trimble 4600, 4700, 5700 and maybe many other models. Last firmware for 5700 (2011 year made) can be found at official Trimble site; for 4700 last firmware
is version 1.30, from 2000 year, no have newer, of course.<br>
</p>
<p><br>
</p>
<p>So, our solve this problem - using TEQC for converting to RINEX with setting correct parameter of GPSweek (-week tag), last 10 daily data file from NVSK was made by this method.<br>
</p>
<p><br>
</p>
<p>Please send us some message, if our data files grow not useful for IGS surveys.<br>
