The High Definition Array is an extremely precise multi-spectral sensor assembly. These devices are usually installed on Science Vessels and Multicruisers and can be widely configured for mission specific requirements. Some of the more sophisticated HDA are used to develop standing wave resonance images of internal structures of objects. These devices can often produce nano-meter resolution at distances of over 1,000 kilometers.
Because of their power support requirements, most HDA Sensor systems are installed in bases and on ships where there is an abundance of reserve generator capacity. Even the more rudimentary HDA sensors are massive power sinks.
The architecture of an HDA can vary extensively, and is built around a modular scheme that allows custom tailoring of the sensor apparatus depending on its intended application. Common high definition sensor kits are installed in many larger ships. Biosensors, chemical detectors, EM field detectors and geo-monitoring packages are often included in Multicruisers as standard HDA systems.
Standing Wave Pulse Imagers, that require megawatt to gigawatt power levels, are seldom mounted in mobile-based kits unless there is a specific need. These SWP imaging packages are prone to failure, as they are known to be extremely sensitive to lateral motiondue to complex antenna hardware requirements.
All HDA systems require a minimum level-5 AA system to interpret the output, although extremely talented sensor systems specialists have been known to read the raw data streams on a limited basis.
