California - Is the Cal Grant different than the State University Grant?

I will be attending a Cal Poly Pomona this year as a junior community college transfer. On their financial aid website, it states that there are Cal Grants, and then there is the State University Grant. Are theses grants two different programs? I only ask because in two years I will be 28 years old and will no longer qualify for Cal Grant. If the State University Grant is different, is there an age limit on it?
