The '''Inter-Range Instrumentation Group''' ('''IRIG''') is the standards body of the [[Range Commanders Council]] (RCC). The group publishes standards through the RCC Secretariat at [[White Sands Missile Range]].

The best known IRIG standard is the [[IRIG timecode]] used to [[timestamp]] video, film, telemetry, radar, and other data collected at test ranges.

The following [[Time signal#Radio time sources|radio time sources]] broadcast IRIG timecodes:

* [[BPM (time service)|BPM]] (China)
* [[CHU (radio station)|CHU]] (Canada)
* [[WWV (radio station)|WWV]] and [[WWVH]] (United States)
