Jorge,

The GDAL library can support ADRG if built with OGDI support.  If you download
the OpenEV_FW 1.5.4 release for Linux or windows from:

   ftp://ftp.remotesensing.org/gdal/openev/

you should be able to use GDAL to do something like:

   gdal_translate gltp:/adrg/usr4/mpp1/adrg/TPUS0101 out.tif

Note that the "gltp:/adrg" portion tells GDAL to use the OGDI gateway,
and for the OGDI gateway to use the adrg driver.  The rest is a real
path to the dataset.

However, most (all?) ADRG files appear to GDAL as subdatasets so you should
do something like:

Input file size is 11904, 8960
0...10...20...30...40...50...60...70...80...90...100 - done.

The key here is picking out the appropriate SUBDATASET_n_NAME's from the
metadata for the overall dataset.

Best regards,
