Dear EarthScope Real-Time Community,

We are writing to announce an update to the reference positions, frames, and epochs for all NTRIP streams supported by high-precision GAGE solutions.

Key Changes

Effective immediately, we have transitioned our stream metadata to the ITRF2014 reference frame. Please note the following specific adjustments:

Reference Frame: Updated from ITRF2008 to ITRF2014.
Reference Epoch: The new reference epoch is 2026-03-30.
Scope: This update applies exclusively to stations within the Network of the Americas (NOTA) and select additional stations where high-precision GAGE positions are available.

These updates ensure that our real-time data products remain aligned with current global standards and provide the highest possible positioning accuracy for our users.

Thank you for your continued engagement with the EarthScope community.

Best regards,

The EarthScope Real-Time GNSS Team
