Help orthorectifying satellite images

[grahamlangley-edwards]

Hi, I am attempting to orthorectify several satellite images.  I have read the help sections on orthorectifying but the images don't have RPC values, so none of the options described will work.  For example, the orthorectify button is greyed out.  Is there a way that I can calculate RPC values for these images to orthorectify them?  Or is there another way to do it without RPC values?  Some info about the images,
Number of bands - 3
Cellsize (X,Y) - 1,1
Format - JFIF
Pixel type - Unsigned integer
Pixel depth - 8 bit

I have Built pyramids for the images and calculated statistics.  Any help would be appreciated.

Thanks,

Graham

Graham,

using 'georeferencing' tool you can georefernce the imagery using exiting georeferenced data, or by adding control points.
check this web course, I think it will help you.
