Orbit supports((Since [[112:orbit_desktop:updates:update_10_2|version 10.2]])) the Amersfoort / RD New Gridcorrection. \\
Both xy grid and z height corrections are implemented. 
\\ \\
To use this implementation the grid files NL_nlgeo04.grd, NL_x2c.grd and NL_y2c.grd need to be available in the Orbit crs directory. \\
Download, unzip and copy to the indicated directory :
  * Downloads : {{technologies:crs:nl_nlgeo04.zip|}}, {{:technologies:crs:nl_x2c.zip|}} and {{:technologies:crs:nl_y2c.zip|}}
  * Orbit crs directory : <Orbit Installation directory>/program/system/crs
  * CRS-name in Orbit: 28992+5709
