• Q&A


• Telemetry:

• The process of measuring at a

distance.

• Aeronautical telemetry:

• The process of making

measurements on an aeronautical

vehicle and sending those

measurements to a distant location

for analysis

• Aeronautical telemetry is the primary

method used to monitor the performance of a system under test.

•If it is ORANGE it is flight test instrumentation

The four basic reasons for using

aeronautical telemetry during testing: •

(1) Test efficiency.

(2) Safety of flight.

(3) Expansion of the test article’s flight

envelope (reducing the number of

required flights)

(4) Preservation of data.

Aeronautical Telemetry


•In 1960, the Air Force, Navy, and NASA were flying the X-15 at Edwards.



PCM Telemetry

• PCM is still in use 51 years later.

• Used to support most DoD test

programs during that time.

• Serial Streaming Telemetry (SST)

• One-way broadcast to the ground.

• No command channel to the test

article instrumentation.

• INET’s goal is to repeat the

success of PCM….

• Increased capacity needed:

• On the test article.

• Between the test article and the

ground:

• While limiting spectrum growth.

• To process, display, and archive

telemetry.

KEY TAKAWAYS:

• Adding open interfaces to existing products:

• Management, Time, & Data

• Interfaces based on open standards

• IEEE 802.3, IEEE 1588, INET IRIG 106*

• "Hub and Spoke" wireless telemetry network.

• Leverages off the existing PCM telemetry infrastructure.

• Utilizes existing airborne and ground antenna systems.

• Ground antenna system auto-tracks the PCM signal.

•*INET Standards transitioning to IRIG106 in the Future
