JASDF GCS-1 & AMI Opher Bombs – How?

I’ve often wondered how weapons like this are used, and it dawned on me that maybe they are similar to something like a TV or IR-guided Maverick.

Is that the case?

Correct me if I’m wrong, but in the case of those types of Mavericks the pilot or WSO just puts the crosshairs on the target, looks on, and away goes the weapon with no further guidance from the launching aircraft.

How would, say an AMX drop an Opher IR-guided bomb? (Are GCS-1 and Opher bombs both IR-guided and thus used in the same manner?)
