An Introduction to IRIG Instrumentation Standards


Founded in 1952 by the US military, the Inter-Range Instrumentation Group (IRIG) was tasked to establish standards for the exchange of information between instrumentation on test ranges.

It sought to create common ground between different instrument manufacturers so that not only could the output from one device be used as an input for another on a test range, but if taken to another test range, it would work with the minimum of configuration.

Today a steering committee and working groups revise and publish these standards through the Range Commanders Council (RCC) based at the White Sands Missile Range (WSMR) in New Mexico, USA. The standards have been adopted internationally for both civil and military aviation as well as missile testing.

IRIG standard are typically identified by a number, followed by the year of revision, and chapter number where applicable. Naturally it can take time for instrumentation manufacturers to implement the changes or features of the latest standards. So it is often worth declaring which version of the standard you need compliance with.


Time Codes:

IRIG 104-60 was the original standard for Time Codes issued in 1960. However IRIG 200-16 is the latest version of the Serial Time Code standards.

Photo-Sonics International offer a wide range of IRIG Time Code generators for use on test ranges and other applications.


Digital Flight Test Recording:

IRIG 106-20 is the July 2020 edition of the standard for digital flight data recording where…


Flight Termination:

IRIG 313-01 addresses the standards for flight termination receivers/decoders.
