This document defines a set of standard application layer interfaces called JAUS Environment Sensing Services. JAUS Services provide the means for software entities in an unmanned system or system of unmanned systems to communicate and coordinate their activities. The Environment Sensing Services represent typical environment sensing capabilities commonly found across all domains and types of unmanned systems in a platform-independent manner. At present, twelve services are defined in this document:Range Sensor: Determine the proximity of objects in the platform¿¿¿s environmentVisual Sensor: Provides common configuration and setup for different types of imaging systemsDigital Video: A type of Visual Sensor that manages digital videoAnalog Video: A type of Visual Sensor that manages analog videoStill Image: A type of Visual Sensor that manages and encodes individual digital imagesDigital Audio Sensor: Provides common configuration and setup for different types of audio streamsDigital Audio Output: Send streaming audio to a destination, frequently a speaker on a remote platformDigital Resource Discovery: Support run-time discovery of RTSP-based streaming audio and videoForce Torque Sensor: Report the forces and torques measured in six degrees of freedomH264 Video Encoding: Configure the parameters of an H.264 based video encoded streamPort Mapper: Provides a bridge between internal and external networks, similar to Network Address TranslationVideo Illuminator: Control one or more lights associated with one or more camerasEach service is described by a JAUS Service Definition (JSD) which specifies the message set and protocol required for compliance. Each JSD is fully compliant with the JAUS Service Interface Definition Language (AS5684).
