PROFILE
Patrick Kappl
Patrick Kappl developed core telemetry, firmware, and protocol features for the SpaceTeam/STS1_COBC_SW repository over three months, focusing on embedded C++ and CMake. He consolidated EPS ADC data models, modernized firmware integrity checks with CRC32, and implemented CCSDS-compliant Space Packet Protocols, including TM framing and secondary headers. His work introduced robust firmware management APIs, explicit RF transmitter controls, and modular telemetry reporting, improving reliability and maintainability. Patrick refactored hardware interfaces, enhanced error handling, and fixed endianness bugs, demonstrating depth in configuration management and unit testing. The resulting codebase supports safer deployments, clearer hardware abstraction, and streamlined mission-critical telemetry operations.

May 1, 2025May 2025 monthly summary for SpaceTeam/STS1_COBC_SW: Key features delivered: - Firmware Integrity Check Modernization and Firmware Management API: Consolidated integrity checks and introduced a unified firmware management API (Erase/Program/Read) with improved robustness and test coverage. Refactored integrity logic into FirmwareManagement and expanded tests. - Telemetry Packet Length Segregation for TM and TC: Introduced distinct maximum packet lengths for Telemetry (TM) and Telecommand (TC) to optimize data transmission and reliability. - Verification Report System for RF Protocols: Implemented generation, serialization/deserialization, and integration of verification reports within the RF protocol stack; updated build configuration to include new sources. - HousekeepingParameterReport for Telemetry Stream: Added HousekeepingParameterReport for encapsulation/serialization of housekeeping telemetry with build/test integration. - ParameterValueReport for CCSDS Telemetry: Added ParameterValueReport to transmit parameter IDs/values (single or multiple) with CCSDS serialization and unit tests. - Serial ReverseBytes Endianness Bug Fix: Fixed an endianness-related type-cast bug in Serial/ReverseBytes and expanded tests for TriviallySerializable and HasEndianness. Major bugs fixed: - Endianness-related bug in Serial/ReverseBytes, with expanded test coverage. Overall impact and accomplishments: - Strengthened firmware update lifecycle with a robust FirmwareManagement API and enhanced integrity checks. - Improved telemetry reliability and observability through TM/TC packet length segregation and expanded reporting/verification capabilities. - Reduced risk and accelerated validation with new serialization paths and comprehensive tests; build now includes new sources. - Facilitated maintainability through modular design and clearer boundaries between firmware management, telemetry reports, and RF verification. Technologies/skills demonstrated: - C++ modular refactoring and API design - CCSDS/serialization and protocol-level testing - Endianness handling and unit/integration tests - RF protocol stack integration and build configuration management - Test-driven development and robust test coverage

Apr 1, 2025April 2025 (Month: 2025-04) – SpaceTeam/STS1_COBC_SW delivered foundational telemetry and firmware hardening with a focus on CCSDS-compliant space packet handling, robust firmware integrity checks, safe transmitter power management, and clearer hardware module structure. Key outcomes include core Space Packet Protocol implementation with TM framing and secondary header support, plus accompanying unit tests; explicit RF transmitter enable/disable controls during initialization; and a strengthened CRC-based firmware integrity check with structured error handling. Subsystem refactors introduced a Payload abstraction, central RF configuration constants, and size/type management utilities, while aligning build with ABI considerations and suffixes. These changes improve telemetry reliability, power management safety, build stability, and maintainability, setting the stage for future mission-critical features. Deliverables and commit traceability: - Space Packet Protocol, TM framing, and secondary header support (commits: 56e9ce9e755ca01c25632b8ccb01507d5bab0997; 8a2eaa0ee5136a6fd3526e0149d4187029b61fd8; 0ad443ae216e824f3f89fc1e97a1b7ecefe45e6b; d19ce3d1a61947fdfbaebc56ba60bab6af581b6b) - RF transmitter power control (commit: 364dc93c26337f932fa2f318a41cc8eefad6b5cc) - Firmware integrity check robustness (commit: a997420cefc71ca0321efc1389e0f62b93be88e5) - Hardware SPI module rename (commit: a3efa10676563ccf884dc9ac5740cd7634dc2cdf) - Internal core utilities and configuration housekeeping (commits: 1909485f1fbd4930e335fc789d8d4bce58471f82; e2c57c677dbe9ce5631a76678d4e0e7604dc9664; d5cb16d5e1f18ae5162a5c1ac70370b194657780; c3bd9be6dbb9703cc6b902e9b5d375db2e82895a; 1d1e15e8ea2a2b95e24b5ada11f1c4ad856e4f9e)
