Integration¶

In order to achieve the project objectives, a system composed by at least the following subsystems is required:

1. MCU (processor)
2. Power management unit
3. GPS receiver module
4. 2-FSK RF transmitter

Processor and power management are considered as part of the Cubesat bus. On the other hand, GPS receiver and RF transmitter is considered as part of the payload.

The implementation also includes a LED and a dedicated antenna for the RF transmitter. GPS receiver is provided with an integrated active patch antenna. The system block diagram is presented below. Interfaces between main subsystems are identified as Int.1, Int.2, Int.3 and Int.4.
