You unlock the Super Jump after a few story missions. This achievement will come to you naturally, most likely within the first 5 hours of gameplay. However, if you wish to get this fast you can of course just keep jumping in place. Or better yet, collect data clusters by jumping around. The trick to maximizing your air time is to hold the jump button while you are airborne. Once you land, release the jump button for another jump and press & hold the button again.
