INTREPID 500S 5.0m S-band radio telescope as ground station

For satellite communication

INTREPID 500S is the S-band radio telescope we designed to receive radio signal from satellites, like the CubeSats, that operate in amateur and commercial S-bands. INTREPID 500S is the ground station composed by antenna, S-band feed, antenna tracking system and pier for concrete base.

By connecting third party receivers (not included with the radio telescope), INTREPID is capable of supporting a wide range of missions with very high flexibility of operations and at a cost that is compatible with a small satellite mission budget.

INTREPID 500S S-band radio telescope uses a 5,0 meter diameter mesh dish antenna with a very high surface precision. The giant GS-400 antenna tracking system allows high precision pointing and tracking of satellites in the sky.

Thanks to specially developed technologies, Radio2Space radio telescopes can be used to support spacecraft exploration and satellite missions in Earth orbit. This ground station can record telemetry data transmitted to Earth from spacecraft or perform radio science (by adding receivers or transceivers not included with INTREPID radio telescope). Radio2Space radio telescopes have very precise mounts that allow accurate tracking of spacecraft, using high directivity antennas – this reduces background noise helping to detect faint signals from spacecraft. Radio telescopes are remotely operated to control antenna position, to detect even the faintest signals.

INTREPID 500S 5.0m S-band radio telescope as ground station: GS-400 antenna tracking system


Much more than an amateur radio telescope.

The INTREPID 500S radio telescope does not use an amateur radio antenna rotator, but the large GS-400 antenna tracking system that we have specially designed and built to be more robust, precise and reliable. The GS-400 antenna tracking system has 400 Kg load capacity with very high precision pointing and tracking (encoders with a read resolution of 0,0015°). It can also be equipped with a special electronic security system (optional) which “parks” the antenna pointed at the Zenith (the vertical position) when the wind exceeds 50 Km/h, offering the lowest resistance to the wind.

INTREPID: Apollo 12 Lunar Module that landed on the Moon just 600 feet from the planned target (Surveyor 3 probe).

INTREPID radio telescopes are named in honor of the Lunar Module “Intrepid” that landed on the Moon during the Apollo 12 mission in November 1969. Astronauts were able to land the Lunar module in the Ocean of Storms just 600 feet from the planned target: the unmanned Surveyor 3 probe that previously landed on Moon surface on April 1967.
