Detailed Description

Mission Computer module, interfacing the mission computer (also known as Copilot), based losely on ISaAC: The Intelligent Safety and Airworthiness Co-Pilot module Based on paper "A Payload Verification and Management Framework for Small UAV-based Personal Remote Sensing Systems" by Cal Coopmans and Chris Coffin.

Copilot is intended mainly for mapping applications.

This module processes messages from Copilot, and either forwards them to the GCS (such as CAMERA_SNAPSHOT or CAMERA_PAYLOAD messages), or responds to them as necessary (such as MOVE_WP).

The module assumes the source of the messages is trusted (i.e. not authentication besides AC_ID check is performed).

Message processing functions.

Message processing functions.

In case of multiple cameras, it is up to the payload computer to send CAMERA_SNAPSHOT messages for each camera at proper interval, so the values don't get overwritten.

void copilot_parse_copilot_status_dl ( uint8_t buf)
void copilot_parse_move_wp_dl ( uint8_t buf)

If MOVE_WP from GCS.

  • processed in firmware_parse_msg(dev, trans, buf); with regular buffer
  • reponse over telemetry (regular buffer)
  • here send WP_MOVED over extra_dl

If MOVE_WP from extra_dl

  • processed in firmware_parse_msg(dev, trans, buf); with extra buffer
  • response over extra_dl
  • send an update to GCS

In both cases, the MOVE_WP message was already processed in firmware_parse here we are taking care only about propagating the change
