Streaming GPS Position Data To a Single Drone

I am trying to use mavsdk to connect to multiple drones and stream their GPS Position data to one drone. So something like grabbing the raw gps/position mavlink data from a few drones and streaming it to a “master” drone so that it would know where the other drones are at. Have any of you made an sdk application that does something similar, or know of an example that is close? if so, posting example code would be very helpful. I am using c++. Thanks!
