FlySpy Patent Liabilities Analysis

2. Overview
The FlySpy project is an autonomous aircraft that flies to waypoints given by GPS coordinates. While at these coordinates, the aircraft will be capable of taking photographs of the location with an onboard camera.

3. Similar Patent #1 Programmable Autopilot System
United States Patent
UAV flight control by
Accurate measurement by multiple sensors for one variable (ex: 3 gyros, 2 pressure, 3 accelerometers) [Claim 1]
Aircraft navigation by GPS [Claim2-7]
Error handling
Landing and taking off
I read reports of people getting up to 100Kb/second using the SPI interface to a file. Depending on the clock we use will determine our speed but I am sure we can achieve the require rate to output the XML format.

5. Similar Patent #2 Precision Approach Control
United States Patent Application
Aircraft control system for taking a photograph when the plane is close to the objected GPS coordinate.
I read reports of people getting up to 100Kb/second using the SPI interface to a file. Depending on the clock we use will determine our speed but I am sure we can achieve the require rate to output the XML format.

6. Similar Patent #2 Precision Approach Control
Similarity
GPS guided UAV that controls airplane’s surface and throttle[Claim4-6]
Difference
Range finder and camera parts are used to measure the distance and angle.
Solution
Using the camera for photograph only
I read reports of people getting up to 100Kb/second using the SPI interface to a file. Depending on the clock we use will determine our speed but I am sure we can achieve the require rate to output the XML format.

7. Similar Patent #3 Anti-hijacking system
United States Patent Application
In an anti-hijacking system for autopilot equipped aircraft, a transceiver communicates with at least one remote guidance facility.
A panic button is activated by flight crew in case of hijacking.
I read reports of people getting up to 100Kb/second using the SPI interface to a file. Depending on the clock we use will determine our speed but I am sure we can achieve the require rate to output the XML format.

8. Similar Patent #3 Anti-hijacking system
Similarity
One button to change the control authority
Difference
Panic button is on the remote controller in our project
The full equations for calculating distances and needed heading with GPS coordinates are costly with trig function. We have found other scaled downed equations that are only accurate within a certain range. Based on the microcontroller clock, will let us know if we may fit all of these calculations within a specific amount of time. The official accelerometer equations for pitch and roll need trig functions to retrieve a correct reading. We may be able to minimize the workload by making lookup tables for specific readings. An example of the GPS functions are here ( ).
