"This standard defines a generic set of electrical interfaces between a host aircraft (""platform"") and an electro-optic/infrared (EO/IR) sensor. This includes connectors@ cabling@ fiber optics@ signals@ and power. Relationship Between Platform/Sensor Interfaces and SAE AS-1C Standards Figure 1 shows the relationship between the various interfaces and the various SAE standards. AS6129 (electrical) covers connectors@ conductors and fiber optics signals@ and power@ and some aspects of data transport. AS6135 (data) covers data (e.g.@ imagery@ metadata@ as well as command@ status@ and response messages.). AS6135 overlaps AS6129 in the area of protocols for data transport. AS6135 and AS6129 are closely bound together because building a system based on these standards is dependent on the requirements from both standards. Also@ requirements put in one standard can impact the options for updating the other standard. NOTE: Regarding Figure 1@ SAE is drafting a standard to cover maintenance and test which@ if adopted@ will likely overlap both AS6129 and AS6135. SAE is also drafting a standard to cover the mechanical interface which@ if adopted@ will overlap AS6129 with regard to connectors. Purpose The intent of this standard is to enhance interchangeability and interoperability amongst equipment provided by various EO/IR Suppliers and avionic systems. Adoption of this standard will improve procurement flexibility for system integrators and platform providers. Platform providers include fixed wing@ rotary wing@ UAS (except for micro-UAS) and lighter than air vehicles. The interfaces are designed to facilitate the: a. operation of EO/IR sensor electrical and mechanical subsystems; b. interconnection between EO/IR sensor systems and the avionics systems hosted by the platform; c. exchange of data and metadata between sensor systems and sensor data processing; d. maintenance of EO/IR systems@ allowing for reduction in maintenance equipment in the field and for test. Application This standard applies to all platforms and EO/IR sensors that interface with each other. AS6129 addresses turreted EO/IR sensor systems. Future revisions of AS6129 may address other classes of EO/IR sensor systems such as non-gimbaled sensors and podded sensors. This standard is intended for application to future sensors and platforms. This includes evolutionary modifications as well as completely new designs. This standard is intended for use by procuring agencies@ and as a general guideline for industry."
