Yes. It is not, of course, the FIDE rating, nor does a player's FIDE rating have any influence on the RHP rating. However, it does mostly use the same Elo system that FIDE uses. Mostly, because there are special rules for provisional players which are (obviously) not used by FIDE, and which aren't part of the Elo system.
Note that it's Elo, not ELO: it isn't an acronym, it's named after Árpád Élő, who devised the system.
