New Firmware update released for DM24 Mk3 digitisers to address GPS Week Number Roll Over (WNRO) issue

DM24 Mk3 Firmware Update

We can confirm that a firmware update for the DM24 Mk3 digitiser is now available. In addition to addressing the 2019 Week Number Roll Over issue, this patch will also address the future 2038 Week Number Roll Over.

This update will apply to:

  • DM24 Mk3 digitisers*
  • DM24S3EAM and DM24S6EAM data acquisition units
  • All DM24-based digital instruments manufactured since 2005

*PLEASE NOTE:This update will not apply to a small number of peli-cased DM24 Mk3 units with a USB socket under the lid. If you are unsure if you have one of these systems, please contact support@guralp.com and they will be able to assist you.

Full instructions for downloading and applying the firmware update are on the DM24 WNRO update page of our website here.

We are not able to provide a GPS firmware update for CD24 digitisers, DM24 Mk2 digitisers or the corresponding integrated instruments

For both of these types of systems we advise a GPS hardware upgrade as the best solution.
 
We are still advising the GPS receiver hardware upgrade as the best solution. In addition to addressing the 2019 NWRO issue, the new hardware will deliver additional benefits such as:
  1. Improved, automatic leap-second support.
  2. Field upgradeable for future-proof operation
  3. Unlike earlier versions, it can be used interchangeably with DM24 and CD24 equipment with the use of adaptor cables
  4. More channels. The new receivers support 56 channels, compared to 12 for the Trimble iQ or 8 for the Trimble SQ modules.
  5. Faster start-ups
Further advice for the GPS NWRO issue including hardware upgrade and firmware update information can be viewed on our GPS WNRO page.
 
The Affinity, Minimus(+) and Fortimus are not affected by the 2019 WNRO.

Support Update on GPS Week Number Roll Over Issue

Update on GPS problem with Week Number Roll Over for GPS units that pre-date 2015

Since we first alerted you to this matter last week, we have been working hard to identify what additional support we can provide to affected customers. We were only made aware of the issue on 27th March and the information provided was subject to subsequent changes. We now have more clarity on the implications for our systems.
 

DM24 Mk3 Patch

For DM24 Mk3 digitisers and integrated instruments (manufactured since 2005) we are now working on a patch and we have high confidence that this will work. If you are unsure which DM24 digitiser you are using, view our guidance on 'Distinguishing between a Mk2 and Mk3 DM242 digitiser'.
 
There will be some limitations to our provision of the patch:

It will only be possible to apply the patch to systems that are on-line if they have an integrated EAM. Digitisers without an EAM will need to be updated on site. We cannot guarantee that a remote update will always be possible.

For any customer who needs to eliminate uncertainty, our advice is to swap the GPS hardware now. You can find more information on our guidance note.
 
As soon as we have tested the patch, we will post an update with instructions on how you can apply it. If you would like to be added to the distribution list to receive this information by email, please send a request to sales@guralp.com

Other Affected Systems

Currently we do not expect to be able to provide a patch for DM24 Mk2 or CD24 systems. For both of these types of systems we advise a GPS hardware swap as the best solution.

Further Updates

We will continue to update the GPS NWRO guidance note on our website with our latest advice.
 
We are aware that this situation provides some logistical challenges for our customers and we apologise for any inconvenience caused as a result. You may have seen in the media that this situation is widespread amongst earlier GPS units supplied by a number of different manufacturers.
