Consolidated Laser Ranging Data Format (CRD) - Version 2.0

This documentation is related to format version 2.0 of CRD (PDF-Version)!

The ILRS Operation Center (OC) checks the following fields of the Consolidated Laser Ranging Data Format (CRD) for Normal Points and Full-Rate data.

--- Important Notice ---
Since 15 August 2019, additional quality checks have been carried out by the ILRS OCs!
The new quality checks will be applied on data which have a production date (H1 record) larger than '2019-08-15 00:00:00'. The are highlight with ^New!
