IRIG 106 STANDARD(S) Purpose of IRIG standards is to promote test rangeinteroperability IRIG 106 has a number of chapters and appendices Most important chapters are:– Chapter 6 – Status and Control– Chapter 9 – TMATS– Chapter 10 – Digital Data Recorder3:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

CHAPTER 10 STANDARD Comprehensive Standard– Used for Hardware and Software Acquisition– Defines Capabilities, Not Architecture Developed by DoD (Range Commanders Council)– Mostly USAF (Eglin AFB and Edwards AFB)– Some Navy Participation– Considerable Vendor Participation Defines.– Data Format– Data Download Interface– Recorder Control and Status Interface Lot’s of Good Stuff, Some Goofy Stuff4:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

TAPE RECORDINGS Ubiquitous Mass Storage for Decades Actually quite advanced Spawned an instrumentation industry Some aspects persist in IRIG 106– Control Commands– Data blocking and format Still used today – “Never underestimatethe bandwidth of a station wagon full ofmag tapes”5:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

EVERYTHING HAS GONE DIGITAL Solid State Media– Removable Memory Module (RMM) Digital Data Representation– Data stored in digital messages– Messages grouped into packets Random Access– Download looks like block oriented disk drive– STANAG 4575 directory structure6:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

IRIG 106 STRENGTHS / WEAKNESSES Strengths– Non-proprietary– Interoperability– Lots of vendors Weaknesses– Not easily extensible– No data object model– Doesn’t network very well11:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

TIP #1 - HOW TO EXTEND IRIG 106 Use Generic Message Data Packets (0x30)– This is the “blessed” solution– Free form data– Down side is no way to distinguish data contents “Steal” an unused packet type– This is the “Robin Hood” solution Steal from the rich, give to the poor– No guarantee of uniqueness or interoperability– Very commonly done Extend IRIG 106 through the standards process13:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

TIP #1 - STANDARDS PROCESS The Range Commanders Council - Telemetry Group (RCC-TG) writes IRIG 106. The Recorders and Reproducers (R&R) Committee writes Chapter 10 of IRIG 106 The TG meats, er, meets twice annually Membership is open to any interested party that is willing to participateconstructively through the Recorder Vendor Working Group (RVWG) Government VendorsYour idea goes hereHopefully this is the result14:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

TIP #2 - EXTEND TMATS TMATS tells you how data wasencoded TMATS doesn’t tell you what datais in the file Data could be interpreteddifferentlyA better data description helps but how?15:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks

TIP #2 - TMATS PACKET “Parameters required by the receiving/processing system toacquire, process, and display the telemetry data receivedfrom the test item/source” Required To Be First Data Packet Documents – Recorder Setup– Data Definitions TMATS is Ugly but Very Useful More could be done with TMATS Will Be Replaced By XML Real Soon Now (RSN)16:May 11, 2011GET CONNECTED to LEARN, SHARE, AND ADVANCE.ITEA 2011 – IRIG 106 Tips and Tricks
