on Ground Station Network (GSN)

Intelligent Space Systems Laboratory (ISSL), The University of Tokyo, and Multidiciplinary Space Technologies Laboratory (MSTL), California State Polytechnic University have agreed to start joint experiments on Ground Station Network (GSN).

As a first step, MSTL is now transmitting uplink commands to XI-IV from their Cal Poly Earth Station. This uplink experiments were succeeded first on March 23. XI-IV made a FM downlink back to ground except the vicinity of Japan for the first time. If you are in California and at its vicinity, you may receive FM packets from XI-IV during its operation by Cal Poly. For more details, please contact Cal Poly Earth Station.
