Create geoid models on
the instrument
Geoid models can be created on the instrument in one of three ways:
1. The geoid field file is stored on a data storage device and can be used when the data
storage device is inserted in the instrument. It is recommended for large geoid field
files. This method is explained in this chapter.
2. The geoid field file is stored in the internal memory of the instrument. It is recom-
mended for large geoid field files. This method is also explained in this chapter.
3. The geoid field file is transferred to the internal memory and can be used at any time.
Refer to "29.1 Transfer user objects"for information on how to transfer geoid field
files to the internal memory on the instrument.
