A SpaceX flight scheduled for Friday will carry dozens of small satellites into space, a “rideshare” launch with low-earth-orbit-bound equipment that will include one particular microsatellite that aims to map the global rollout of 5G networks, with a view from space.
The cube satellite nicknamed Charlie, about the size of a carry-on suitcase, bears a specialized radio frequency sensor that is about five inches square, with three antennas that can detect radio frequency activity up to 40 GHz.
