I am a new user of GRASS GIS.

How can I mosaic different satellite imageries using GRASS GUI?

I was trying to use i.image.mosaic, but could not succeed. I have been looking for an online tutorial but could not find one.

You can use r.patch for that (see help file)

You probably want to set the region first to encompass all raster layers, after which you can use r.patch to 'mosaic' the layers. The following example is from the helpfile:

export MAPS=`g.mlist type=rast sep=, pat="map_*"` 
g.region rast=$MAPS -p
r.patch in=$MAPS out=mosaic

Use the keyword export when you are using a Linux and Bash combination.
