The GD200 Gigabit Detector is a compact, high-speed optical-to-digital converter, used in optical ground stations, currently capable of receiving data rates up to 1 Gbps.
Developed for nanosatellites, this laser communication solution converts data contained in digital laser signals into a digital bitstream, ready to be processed by a high-speed data handling system. Its plug-and-play electrical interfaces and easy mounting make it ideal for use in optical communication ground stations as well as experimental setups for optical communication.
AAC Hyperion is working with known Optical Modem suppliers to ensure compatibility with the laser communication supply chain. If required, an integrated Modem & Detector Solution can be made available. It will allow easy integration and provide a convenient one-stop-shop experience. The GD200 has been developed together with TNO.
Flexible Mounting
The GD200 is versatile in its mounting and is easy to integrate into almost any setup. Four mounting options are available to cover various scenarios and meet differing user needs.
Easy Communications
A standard USB Type-C port ensures easy connection to any computer, whilst a D-SUB 9 connection enables using longer cables and the popular RS485 communication standard.
Configurable
The GD200’s output amplitude can be configured to different voltages. This allows for easy adaptations to modems of a variety of suppliers.
