data acquisition
and augmented by new
techniques, such as
low-density parity
check (LDPC) and
space-time-code (STC),
to operate in noisy
environments and to
increase the link
distance. These
enhancements allow
the FTI system to
support missions at
great distances.
Future FTI
architectures could use
transmitters with C-Band transceivers
that support wireless Ethernet standards,
such as iNET. In this case, the FTI system
integrator could control the entire system
from the ground during live flight tests
using the transmitter’s uplink capability.
It’s important that onboard recorders
support the acquisition and recording of
avionics bus and network traffic packets,
such as IRIG-106 Chapter 10, iNET TmNS,
DARv3 and 1394b and optical Fibre
Channel (oFC) data, as well as GbE traffic.
The acquired data can be recorded as
aggregate (bulk) or segregated to different
solid-state media cartridges for security
reasons. The selected data can also be
output as a PCM for real-time RF TM
transmission. New high-speed recorders
support the acquisition of 10 GbE packet
traffic for bulk and selected data recording
on high capacity solid-state media
cartridges to allow FTI system integrators
to collect all the data they need.
Flight test data must be collected with
fidelity and without failures. FTI system
designers and engineers, need to be expert
in test and measurement, data acquisition,
recording, and analysis. As the FTI industry
transitions to networked architectures,
system designers and engineers also need
to become well-versed in networking. By
leveraging the expertise of an FTI total
system solution provider, the system
integrator can realize a complete
networked FTI system, that eliminates the
time, cost, and program risk that comes
from trying to build a system solution
using products, often with different
programming software and recording
formats sourced from multiple suppliers. \\

receivers, de-commutators,
and data analysis software,
should seamlessly integrate
into the system as well.
FTI system designers are
therefore inclined to
partner with a FTI total
system solution provider as
their products can be used
to design the entire airborne
network infrastructure from
a hardware, software,
network, data type, and data rate
flow perspective, and to manage the
on-board data recorder’s real-time
sustained recording capabilities. In
addition, system designers can leverage the
total system solution provider’s experience
to design their RF network for efficient use
of the available bandwidth through highly
efficient RF transmitters and
transponders, and to manage the FTI
system’s size, weight, and power (SWaP).
A recent example of an FTI product
optimized for bandwidth and power draw
efficiency involved a new tri-band
transmitter, which operates in L-, S-, and
C-bands. The bandwidth efficiency is
achieved via modern modulation schemes,
