Summary
Nanoavionics' payload controller is a subsystem dedicated to interface between payloads and the NanoAvionics CubeSat bus. It has a number of different interfaces for payload connection and can buffer data from payloads. It also controls the S-band transmitter or transceiver to transmit the buffered data to ground stations.
Key features of the payload controller include:
- Integrated TRC
- microSD NAND Memory support (up to 2 x 32 GB)
- Three On-Board PWM Controlled H-Bridges
- PWM Outputs
- FreeRTOS
- In-Orbit firmware update
- Firmware Power-on-check and Restore
- RFS – Redundant Record-based File System
- CSP Support
- Self-Diagnostics
- Dynamic CPU Frequency Control
- User-friendly Console
The software included in this subsystem is based on a robust, modular design, which includes the file-system, CLI, CSP, configuration and firmware update engines. These features together create a user-friendly environment for setting up and running the subsystem. Each of these modules, along with subsystem-specific configuration and feature details are described in software datasheet document.
