ZRP igororotse imwe axis izuba ikurikirana sisitemu ifite umurongo umwe ukurikirana inguni ya azimuth yizuba. Buri cyiciro gishyiraho ibice 10 - 60 byumuriro wizuba, uhabwa umusaruro wa 15% kugeza 30% hejuru ya sisitemu ihamye-ihanamye kurwego rumwe. Sisitemu ya ZRP igizwe na axis ikurikirana izuba ifite ingufu zitanga ingufu mukarere k’uburinganire buke, ingaruka ntizaba nziza cyane mu burebure buri hejuru, ariko irashobora gukiza ubutaka mu turere twinshi. Flat imwe axis izuba rikurikirana sisitemu nuburyo buhendutse bwo gukurikirana, bukoreshwa cyane mumishinga minini.
