navigating it self to a
predetermined
location on earth
autonomously.

SUAV

Small Unmanned Aerial Vehicle



Advantages vs. Ground Traverse Vehicle


Higher return velocity


Requires less power


Has a better chance against a headwind





Obstacles to be overcome


Autonomous flight control


Navigation in 3D vs. 2D


The intricacies of aerodynamics


HALO (High Altitude Low Opening)


Rapid Descent Phase


Take initial heading


Begin steering toward the target


Release parasail at 1100 ft.


Parasail Descent Phase


Continue steering towards target via parasail

launch


Failure


Module failed to eject from carrier

Cause of Failure


Module built to previous carrier
specifications.


Carrier unable to seal
properly


HCX Flight computer confused at apogee
event sending carrier back into rocket

New Direction


New Air Frame Design


Built to current carrier specifications


25% volume increase for electronics


Parafoil chamber volume increase




Improved Electronics


Isolated electronic systems


Easier programing

GPS Navigation


Orientation relative to the target
determined via GPS signal

uses the angle of the craft’s position
relative to the target to determine
whether to turn or not


greater than a certain degree


right turn


Less than a certain degree


left turn

existent


Module deployment with parasail deployed
upon exit from carrier


GPS data from PB2 (passenger board


data
collection) corrupt. **possible cause


weak
GPS signal**


Navigation appears to be working


module
found heading towards target, while rocket
parts found further away.
