RMaps previously provided free satellite imagery, and any geo-location could be shared from OSMand to RMaps, to quickly show a satellite overview. (Tiles from ARCGIS IIRC)
What is the current state of satellite imagery in fdroid?
How can an OSMand location be quickly opened as a satellite view?
Edit: Extra info is, I'm looking for an offline satellite image solution. Full pre-loading of a specific areas, before travel.
With RMaps, it was possible to pre-load the tiles for the remote-location needed at various zoom-levels, before travelling a few 100kms from cell-towers, and then still being able to access an offline-satellite-view of those locations when there.
OsmAnd does support this. You need to activate the overlay/underlay you want to download, press&hold anywhere on the map, then in the menu do Actions > Download Map.
It's not elegant but you can effectively preload the tiles by just swiping around the relevant zone at a bunch of zoom levels while you have a connection. The cache is not actively purged so the tiles will be available when you need them. I've regularly done this.

I think it depends a lot on where you are. Where I am, the government (kinda unofficially) provides excellent quality (<10 cm/px in some cities, and <50cm/px for the entire country) orthographically adjusted aerial imaging, that's a lot better than any commercial solution.
Hey, you can add the satellite imagery you need by doing Configure Map > Underlay > Underlay map > Add more. Then you can select the imagery you just added from that same menu.
After you've selected the underlay map, you can pre-download the images for offline use by viewing the part of the map you want to download, touching&holding anywhere on it, then doing Actions > Download Map.
