Then why did BoS crossed the wasteland to know if the East Coast BoS was alive before Fallout 3? If they had a satellite to communicate they wouldn't need to risk such a dangerous mission. Why is there no mention of a satellite in Fallout 1 and 2? Because it didn't exist. Anyone at BoS would say to the player if the player asked about it because the devs would have put a dialogue option for something so important. Just the mere fact you don't know this shows how clueless you are about lore.
