JDRS

The Japanese Data Relay System (JDRS) is in developed

To provide optical data relay services for Earth observation data and others, and to improve the value of Earth observation satellites and other low earth orbit (LEO) satellites.

Using a new high-efficiency, high-power optical amplifier with a user data rate 2- to 4-fold higher than the 1.8 G bps data rate for JDRS.
