The FLOCS project is made up of an AVR 32 Microprocessor, a series of Serial Peripheral Interface (SPI) and Two Wire Interface (TWI) sensors, physical and wireless communication equipment, as well as a computer program designed to display the information acquired through the system board. For detailed information on each of these components please see our Technical Specifications page.
These components are linked together by a custom built sensor package (shown below) which encorporates on-board sensors as well as multiple interface ports to support off-board sensors as well as future expansion.
The sensor package reads sensor data and aggregates the information into internal buffers. These buffers are then transmitted over an on-board Ethernet port. Utilizing the "Bullet" transmitter (shown below) the Ethernet data is able to be transmitter over large distances without the need for high powered transmission hardware built into the sensor board.
On the receiving side of the system, an AirGrid M5 receiver (shown below) is used to capture the data sent from the bullet transmitter. The receiver gathers the data from the air and re-transmits it over another Ethernet network, which we use to view the data.
The received data is captured on a laptop computer which uses a specially built "Monitor" program to interpret the data packets and display the current speed, orientation, and position of the sensor package (shown below). This software can be used to view the position details of an aircraft or other device.
A graphic describing the project workflow is shown below. The sensor package/transmission stage is shown in orange, while the receiver/Monitor section is shown in green.
