5、rne EO/IR Systems, Mechanical RATIONALE This document was created to standardize the mechanical interface between aircraft and Electro-Optic (EO)/Infrared (IR) sensors. This activity was initiated at the request of the U.S. Navy in 2009. PREFACE AS6169, Interface Standard, Airborne EO/IR Systems, Me
6、chanical, is a standard that defines the mechanical interface between aircraft (manned and unmanned) and onboard EO/IR Systems. Its purpose is to promote platform to sensor system interface standardization by providing substantial, but not 100% commonality, interoperability, and limited interchangea
7、bility. This document was prepared by the AS-1C4 Electro-Optic/Infrared Mechanical Interface Task Group, under the jurisdiction of the AS-1C Subcommittee, Avionic Subsystems, of the SAE AS-1 Committee, Platform Systems and System Integration.

SCOPE This standard defines the mechanical interface and specifies provisions for the electrical and environmental connectors between the host aircraft (“platform”) and a turreted
14、electro-optic/infrared (EO/IR) sensor. 1.1 Relationship between Aircraft/Sensor Interfaces and SAE Standards Figure 1 shows the relationship between various interfaces and their related SAE standards. FIGURE 1 - RELATED SAE STANDARDS AS6169 overlaps AS6129; AS6129 (electrical) covers connectors, pow
15、er, conductors, fiber optics, and some aspects of data transport. AS6129 defines the platform-sensor interface (PSI) in two configurations, an EO/IR sensor with and without an external control unit (ECU). In the case where the sensor includes an ECU external to the turreted EO/IR sensor, AS6129 defi
16、nes the PSI at the ECU, not at the turret. In the case where the sensor includes the ECU internal to the turreted EO/IR sensor, AS6129 defines the PSI at the turret. In contrast, AS6169 covers the mechanical mounting of the turreted EO/IR sensor to the platform plus locations for electrical and envi
17、ronmental connectors at the turret regardless of the configuration. AS6135 (data) covers data (e.g., imagery, metadata, as well as command, status, and response). AS6135 overlaps AS6129 in the area of protocols for data transport. AS6165 defines the use of the sensors electrical and data interfaces
18、for maintenance and test purposes and as such only overlaps AS6129 and AS6135. 1.2 Purpose The intent of this standard is to enhance interoperability, commonality, and interchangeability among equipment provided by various EO/IR suppliers and the platforms to which they are to be integrated. Adoptio
19、n of this standard will improve procurement flexibility for acquisition, system integrators, and platform providers. Relevant platforms include fixed wing, rotary wing, UAS (except for micro-UAS), and lighter than air vehicles. 1.3 Application This standard applies to all platforms and turreted EO/I
20、R sensors that interface with each other. This coverage encompasses sensors and platforms presently in concept development stages, future platforms, sensor developments, and upgrades to legacy platforms. SAE AS6169 Page 4 of 64 2.
