I don’t know about an Android app, but I doubt you’ll be able to get that receiver pointed any better than what you have. 8dB is amazingly high–and that’s inside of an enclosure.
Feel free to take pictures. Most people on the forum have not seen the Alpha2 in the wild.
Last January, Outernet had a post regarding Satellite Director Version 1.52 - - an Android App available from www.zekitez.com from Frans Nijhuis.
It’s designed for Ku Band satellite pointing, so it is very accurate. It doesn’t have the Intelsat birds in it, so you’ll have to pick the closest Ku band bird. Ken
