Well, in a nutshell, an AHRS provides you with attitude / heading information while the IRS also gives you position information (and with that also data like GS, true track, Wind data, magnetic heading / track)

If you take a look at current jet aircraft, the IR / IRU systems have a ATT position. When switched to ATT, the IRS is basically just an AHRS system (but you'll have to provide a heading reference manually)

All solid state, [email protected] ring gyros stuff in these days.

Couple an AHRS equipped aircraft with GPS and you basically have the same information available as an IRS equipped aircraft.
