RINEX 4.00 Now Available

By IGS Central Bureau

We are pleased to announce that the IGS RINEX Working Group has just released the new RINEX 4.00 format and is now available on the IGS Website.

RINEX 4.00 (2021) is a major revision of the format document to modernize the Navigation message files to be able to accommodate the new navigation messages from all the GNSS constellations, and system data messages such as; ionospheric corrections, earth orientation parameters and system time offsets.

The RINEX Working Group Chair has prepared an Open Letter to the GNSS community about the new RINEX 4.00 format to highlight and explain a bit the changes from the previous RINEX versions.

The new format is described in more detail on our Format and Standards page. For more information on the RINEX updates and activities, we invite you to visit the RINEX WG Page.
