I think it's more likely based on the Phoenix Ghost, both drones have been floating around the middle east for a while. So Iran could've easily acquired examples covertly, or it could just be an indigenous development. Loitering munitions all have a certain design pattern to them that makes them all appear fairly similar. It's like how all stealth jets kinda look the same, it's demanded by physics and engineering not necessarily imitation.
I'm quite confident that Iran has acquired Javelins by now, either through Ukraine or Syria so I'm somewhat bullish on a successor to the Saeghe 1/2 (M47 copy) appearing sometime soon. But doesn't Iran already have a Javelin equivalent with Almas (Spike copy)? To reiterate, I'm fairly confident that Iran has acquired them but is there much of a point when Iran already has Almas? Parallel programs seem to be an unfortunate feature of Iran's MIC so I wouldn't be surprised if a copy turns up.
