HERMES is the first Internet-to-Orbit voice/data gateway, a system capable of connecting Internet users and spacecrafts in space, manned or unmanned, like satellites.
Using HERMES a user anywhere in the world can received the live signal of satellites passing trough the range of the HERMES-A ground station, located on Guayaquil, Ecuador. The maximum tested range of this ground station is 6000km line of sight.
HERMES has 4 modes of operation:
MODE A (Alpha): Reception of data from orbit and relay trough Internet.
MODE B (Beta): Uplink/downlink full duplex connection between computers on the Internet and orbiting spacecrafts.
MODE C (Gamma): Half duplex voice conversation between any computer on the Internet and manned spacecrafts.
MODE D (Delta): Automated APT signal relay from weather satellites to any computer on the Internet.
