It's not just a single organisation, many organisations have satellites orbiting earth, you can watch a Space X launch live to see. It's simply an unreasonable conclusion to draw given the amount of assumptions required, and lack of evidence provided. Without even delving into the science, it is unreasonable to assume that every astrophysicist in the entire world is involved in some massive cover up, and that consequently, nearly all known science is completely false (all science explored by all scientists for the last few hundred years, including great minds such as Einstein). The proposed motive for this cover up is weak at best. Science isn't some unfounded weak code written by the elite, it is testable, provable, and has been done so by many independent sources globally for hundreds of years. To be fair, you haven't stated a firm opinion, so I'm not criticising; but I recommend you write out all of the evidence/motive for flat earth, then study the evidence for spherical earth and it becomes preeeetty feckin' obvious =)
