“…The Japan Aerospace Exploration Agency (JAXA) commissioned the experimental data relay test satellite (DRTS) in 2002 . Optical and Ka‐band ISLs were verified, including an experiment with a Ka‐band ISL between DRTS and Envisat . Both TDRSS and DRTS have steerable Ka‐band receive antennas limiting the maximum number of simultaneous ISLs to the number of on‐board antennas (plus optical transceivers).…”

“…4 Optical and Ka-band ISLs were verified, including an experiment with a Ka-band ISL between DRTS and Envisat. 5 Both TDRSS and DRTS have steerable Ka-band receive antennas limiting the maximum number of simultaneous ISLs to the number of on-board antennas (plus optical transceivers). TDRSS satellites can receive data by means of electronically steerable antenna beams in the S-band from five senders simultaneously (ground-based beam-forming), while transmitting data to one.…”

Summary From a geostationary Earth orbit (GEO) satellite's perspective, a low Earth orbit (LEO) satellite is visible on more than half of its orbit. Albeit the free‐space loss of an inter‐satellite link is much higher than the one of a direct ground link, considerable data rates and download volumes can be achieved. In this paper, we describe the system architecture of an integrated approach for a data relay satellite system and the development of LEO satellite and ground station modems. The approach allows serving several small and inexpensive LEO satellites at the same time both with low rate telemetry/telecommand links and with high rate download of sensor data.
