SmartNet California Adjustment Announcement - May 25, 2013

We wanted to take a moment to alert you of the upcoming changes that will affect ALL users of SmartNet California.  We will be taking the network offline starting Saturday night May 25 at 10:00 PM ET to begin importing the new broadcast coordinates for California into our system.  During this time the network will be completely offline and will not resume operations until Sunday morning, May 26 at 6:00 AM ET.  

As we announced last year, we will be conducting bi-annual adjustments and updates of the broadcast coordinates to combat the error that is introduced as a result of the plate movement in California.  While this adjustment is VERY important to make sure we can maintain the internal consistency that our users demand, it will not produce as dramatic a shift as what was seen in October when we moved to the new reference frame and epoch for all of SmartNet North America.  On average, this adjustment will produce an overall shift of approximately 20 mm in California.

If you are new to SmartNet or didn't have an opportunity to attend one of our Adjustment Launch webinars last year, please visit to view the webinar replay.  This will give you a very good understanding of why we did the original adjustment and coordinate update, as well as why we are on a bi-annual cycle in California.  Please keep in mind the webinar was produced for the original adjustment in October and the coordinate changes were MUCH larger in October than they are now.  Again, you will only see approx. 20 mm of change with this update, this is VERY important to understand.  The update on May 25th will NOT produce the 8+ cm that was experienced last fall.

Even with this smaller coordinate change, it is still recommended that you perform a transformation, localization or calibration and tie to existing control to compensate for these changes in the field.  We will also be publishing transformation information in the coming days to help our users deal with this update as well.  If you are unsure about how perform a transformation or how to use the provided transformation information, please contact your local hardware/support representative.  

In addition to using local resources for support, we have also developed a number of tools that you can use to find answers to a number of common questions about the adjustment or about using SmartNet.  If you want to learn more about these tools please visit and search for the keyword "tools".  Also to better help you understand the support procedures surrounding the adjustment, please see the general outline below, these procedures were developed to make sure all questions and issues get resolved in a timely manner.
