• Altitude • Tested by David Thomson in NOAA Astronomy Laboratory pressure

chamber. Passed operational tests at ~51km (0.53 mbars) for 8 hours.

• Shock • Dropped 9 stories while logging 3-dimensional accelerometer data

(resultant = 200.2 g)

• Flight • Steered fins and controlled parachute ejection system inside 2.5m

rocket (reached 400m altitude)

• “The Saw Test” • Sawed an 8-slot chassis in half to create a 4-slot (not powered

during sawing)

• Motorcycle In-Vehicle Data Acquisition • Installed in Yamaha R6 for in-vehicle DAQ (engine mapping) and

rapid control prototyping

• Skydiver Datalogging • 4,400m test jumps conducted July 1 in Orlando Florida • Visit CompactRIO Embedded System Developer’s Forum for details

Linux Operating System NI Linux Real-Time Operating System

ni.com

• Operating system created under the model of free and open source software development and distribution

• First released in 1991 for x86 but has been ported to other computer hardware platforms including ARM

• Common OS for servers and big mainframes

• Linux is used in a wide breath of embedded systems including:

• Mobile phones (Android)

• Tablets

• Network routers

• Televisions

• Video game consoles

Linux Operating System Background

What makes our Linux flavor unique?

Pre-emption offered through RT scheduler to make Linux deterministic

Jitter is on the same order of magnitude as other RTOSs

Loop Rate performance is substantially improved over current value cRIO

S.E.A Structural Monitoring

“By leveraging the open Linux-based real-time operating system on a commercial off-the-shelf controller, we could port our existing Linux software components in a very short time. That saved

us at least four months of development time.”
