First time I heard about these objects I thought about this presentation for Google Loon, and all the research around high-altitude gliders that has taken place in recent decades. https://www.slideshare.net/Funk98/highaltitude-solar-glider-for-internet-access https://www.slideshare.net/Funk98/highaltitude-solar-glider-... A high altitude glider being repurposed for surveillance seems like a plausible explanation for all this.
