Remarks

Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9 or nm/m. Superseded by parameter values derived from transformations to ITRF2020 (change in scale difference), see EPSG:10139.

Frequently Asked Questions

How do I convert ITRF88 to ITRF89 coordinates?

Use the coordinate transformation tool above to convert ITRF88 (EPSG:4910) to ITRF89 (EPSG:4911). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geocentric domain) method with 0.01m accuracy.

How do I transform ITRF88 to ITRF89 using Proj4js?

Use proj4.defs to define both EPSG:4910 and EPSG:4911, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the ITRF88 to ITRF89 transformation?

This transformation (EPSG:9020) has an accuracy of 0.01m using the Position Vector transformation (geocentric domain) method. Area of use: World.
