Problems & Solutions
Problem
Untested hardware and software lead to
crashes.
Solution
Simulate flight before actual flight to ensure
success.
Problem
Old trainer cockpits that aren’t useful
anymore and don’t have a purpose.
Solution
First-person cockpit flight
simulator capable of training pilots.
Problem
Weak connections between UAV and
ground control station make communication
difficult.
Solution
Azimuth-elevation antenna tracking system allows for
stronger connection and better
communication with UAV and Ground Control Station.
Constraints
Movement Detection• Controls should be read with miniscule degrees of change
Compact Design• Hardware components must fit inside of the cockpit with room to
move controls
Technical ConstraintsFirst Person Cockpit
Antenna Accuracy• Tracking system must ensure the antenna keeps UAV in range of
the main lobe
Operating Distance• Operate within line of sight and have an unobstructed view
Tracking Mechanics• Gimbal must cover a range of 360C azimuth and 90C elevation
within 40 seconds
Technical ConstraintsAntenna Tracker
Practical ConstraintsSustainability
• The connections and software used for the product will not constrict the systems ability to add new devices.
• Must not be specific to the Xipiter team and must allow for minimal hardware to adapt for the new devices.
• This implementation will add versatility to the system.
Practical ConstraintsEconomic
• Cockpit system: upgrade.
• HITL: open source software.
• The antenna tracking system: compatibility with the Xipiter team.
• Working with the Xipiter team gives additional access to parts.
