By outlining the interfaces between these components, the datasheet aims to facilitate seamless integration and operation for system engineers, integrators, and developers working system.
Scope
This document is intended for use by system engineers, integrators, and developers working with ULS-Heli-G2 systems. It provides detailed information on the system.
System Base Components
Transmitter (Ground Unit)
Figure: ULS-Heli-G2 Transmitter A transmitter is a device placed on the ground (platform, moving object). It emits a signal in the Infrared range and serves as a kind of beacon. Transmitter marks position for drone landing. The primary function of the transmitter is to continuously send out a coded signal that can be detected and interpreted by the receiver unit onboard the XCopter. This signal contains critical information needed for the operation of the system, such as positional data, commands, and status.
Receiver (Onboard Unit)
Figure: ULS-Heli-G2 Receiver A receiver is a device that is placed on board an aircraft. The receiver decodes this signal to derive flight information such as positional coordinates, real-time transmitter status updates, and landing guidance. It interprets the data to navigate accurately and ensure drone follows the intended flight path. It provides feedback to the autopilot systems, such as Ardupilot and PX4, to adjust the flight parameters as needed for optimal and safety landing or hovering above.
