Description / Abstract:
This standard defines the use of data interfaces between a host
platform and an electro-optic/infrared (EO/IR) system for
maintenance and test (MT) purposes. In particular, this
standard defines the use of the data interfaces in order to
facilitate the:
a. confirmation of system performance and function;
b. external initiation of built-in-test (BIT) functions;
c. performance of other diagnostic tests of system health;
d. downloading MT data;
e. uploading software changes.
This standard does not cover mechanical or electrical
interfaces, nor does it define the basic platform-to-sensor
communication protocols and formats. Furthermore, this standard
does not address software changes that are made by the manufacturer
and not accessible at the sensor interfaces. Data protocols and
formats are covered by AS6135. Electrical interfaces are covered by
AS6129. This standard covers the use of the interfaces defined by
AS6129 and AS6135 for the purposes described herein.
Purpose
The intent of this standard is to enhance interchangeability and
interoperability amongst equipment provided by various EO/IR system
vendors and associated electronic systems with respect to MT
of the system during its development and employment. In so doing,
this standard will reduce acquisition and life cycle costs
associated with EO/IR system acquisition and integration and reduce
the costs and proliferation of maintenance support equipment and
associated software and training. Furthermore, it is envisioned
that the ability to fully exercise the sensor system and download
all relevant data while installed on the aircraft ("platform") will
permit more robust assessment of system health without requiring
deinstallation of the turret or associated electronics.
Application
This standard applies to platforms and EO/IR systems that
interface with each other. Initial release of this document will
address turreted EO/IR systems with future releases addressing
other classes of EO/IR systems such as pods and warning sensors.
This standard is applicable both to the development of new sensors
and platforms as well as to upgrades to existing platforms or
sensors.
