Modeling and Simulation

the EMBRAER A-29, a Super Tucano advanced trainer aircraft. With the introduction of SisTrO, carrying out store release experimental flight test campaigns should be more effective without jeopardizing test results, accuracy, and
safety.
The IPEV team was impressed by the ability of SisTrO to
produce the required results in real-time with high accuracy
(typical >±6mm @1sigma). Moving forward, IPEV plans to
build two further SisTrO units with enhanced capability, such
as dual but not simultaneous vision.
So far, SisTrO is the only optical tracking system designed
for flight test applications that can produce the 6DoF trajectory (Figure 6) in real-time. SisTrO represents a significant advancement over similar systems, which are not
qualified to be airborne or cannot work in real-time with
high-speed and high-resolution images up to 1920 ¥ 1080
at 400 frames per second. Although there are several highspeed, high-resolution cameras that can be used for flight
tests and image capture and storage in real-time, they can
only perform image and data processing as a post-mission
operation. Therefore, these cameras will slow down the
flight test campaign's productivity to a typical single test
point every half day.
In contrast, SisTrO can execute up to two test points in a
single flight without jeopardizing the safety of the test or the
accuracy of the results. Therefore, SisTrO will improve the efficiency of such flight test applications. Furthermore, SisTrO
has the capability to expand, allowing a broader range of applications.

Summary
While a vendor can provide value by supplying clients
with single-board computers that are high-performing,
rugged, reliable, and low-maintenance, it can create even
more value by working with a client beyond hardware.
During the development of the optical tracking system
SisTrO, IPEV had access to high-speed cameras and high-performing processors. However, it was very challenging to
transfer a large amount of imaging data from the camera to
the processors quickly and continuously. The traditional
transfer via Ethernet was not up to the job.
ADL enabled IPEV to succeed in the SisTrO project by doing
the following:
* Began with a solution that is 80% complete and worked
with the client to 100% completion.
* Used a frame grabber as an interface to the processor, making it easier to finalize the processor configuration.
* Provided the key contribution that moved the project from
testing to full functionality in less than nine months.
To IPEV, ADL's technical solution enabled the success of
the SisTrO project. Instead of 2 test points per day by typical
systems, the SisTrO system can achieve at least 2 test points
in a single flight while ensuring test safety and data accuracy.
