2014 Iridium Time Epoch Change | New Roll Back Information

As part of standard satellite network operations Iridium periodically resets the Iridium L-Band system time count, otherwise known as a “re-epoch”.

When Iridium reset the L-Band count at 10:00:00 EDT on June 17, 2014 to Era 2, a small number of Iridium partners notified us that their applications had an issue with the re-epoch.

Iridium is committed to the operation of ALL applications on our network. Therefore we made the decision to “roll back” or reset the Iridium L-Band Counter back to Era 1.

Iridium is hereby providing advance notice of the “roll-back” to all customers in order to allow adequate time for any technical preparations to occur in order to transition your solutions back to Era 1.

  • The activities to “roll back” the Iridium L-Band counter will start on June 30th at 15:37:00 UTC
  • The Iridium L-band counter start time will revert back to March 8th, 2007 3:50:21 UTC

Iridium plans to conduct the re-epoch again in the 1st Quarter of 2015 and will provide additional guidance later this year, and you should consider this when preparing for the rollback.
