Test Avionics Transponders and Secondary Radar with NI and Hangxin


Hi. My name’s Ben and
I’m an engineer at National Instruments. Today, I’m going to show you
a solution for functional test of avionics, including
navigation aids, surveillance systems, radio communications,
and radio altimeters. This solution is made by
Guangzhou Hangxin aviation technology and is based on
the NI PXI Vector Signal Transceiver. This is the Star 1000 and
it’s a standalone test set that can be
used on a bench top or mounted in a rack system
for validation, manufacturing, or maintenance level test. This test set is tasked with
dissipating a lot of energy. So you may hear
the fans behind me. When I turn it on, the
system boots directly into the test
selection interface. From this menu, I can
choose the transmit and/or receive
mode for a variety of CNS avionic standards
with the touch screen. To demonstrate how
the test set works, I’m using a smaller,
portable version of Hangxin’s avionics
test set, the Star 3000, to simulate a CNS avionics
device under test. I’ll set the Star 3,000
to operate as a mode ACS transponder. Now back on the
Star 1000, I need to change the test set to
generate a mode ACS air traffic control signal. In this way, the
Hangxin test sets can act as a base station,
stationary beacon, or mobile transponder. Now that I’ve begun transmitting
and receiving an air traffic control mode ACS signal, you
can see the Star 1000 is now responding to changes I make
on the Star 3000 showing that the Star 1000
is successfully communicating with the
airborne surveillance system– in this case, the star 3,000. The Hangxin Star 1000 and
3000 contest the function of both stationary and mobile
transponders, transmitters, and receivers for surveillance
ATC transponder modes A, C, and S, and TACAN with TCAS,
which is under development now, nav aid modes ILS, VOR, Marker
Beacon, ADF, DME, and MLS, high frequency and very high
frequency radio communications, radio altimeters, and other
surveillance, nav aid, and communications modes. The Star 1000 and Star 3000 are
both based on the NI PXI Vector Signal Transceiver. Thanks to the user programmable
FPGA on this instrument, Hangxin was able to use their
knowledge of the communications signaling and measurements
to implement those onto the FPGA of the instrument. Having the communication
algorithms on the instrument allows the Star 1000 and Star
3000 to both simulate and test the function of these
communications systems deterministically,
at the same time, and do it much faster and
more efficiently than is possible with traditional
fixed function instrumentation. To learn more about the
Star 1000 and Star 3000, visit hangxin.com. To learn more about how building
test systems on the NI platform can reduce the risk
of schedule overruns, decrease the overall cost,
