Report On: Fetch PR 23315 For Assessment

PR #23315

Summary

This pull request addresses an issue in the PX4 Autopilot's Extended Kalman Filter (EKF2) module, specifically related to the GPS vertical speed (vspeed) check. The changes ensure that the filter's vertical velocity (vz) is valid before performing the GPS vspeed check. This aims to improve the stability and accuracy of the system by preventing potential discrepancies between GPS vz and EKF vz from causing GPS fusion failures.

Detailed Diff Analysis

// Original Code
const float vz_diff_limit = 10.0f * _params.req_vdrift;
const float vertVel = math::constrain(gps.vel(2) - _state.vel(2), -vz_diff_limit, vz_diff_limit);
_gps_velD_diff_filt = vertVel * filter_coef + _gps_velD_diff_filt * (1.0f - filter_coef);
_gps_check_fail_status.flags.vspeed = (fabsf(_gps_velD_diff_filt) > _params.req_vdrift);

// Updated Code
if (_filter_initialised
    && (isVerticalVelocityAidingActive() || isVerticalPositionAidingActive() || _control_status.flags.vehicle_at_rest)
   ) {
    const float vz_diff_limit = 10.f * _params.req_vdrift;
    const float vz_diff = math::constrain(gps.vel(2) - _state.vel(2), -vz_diff_limit, vz_diff_limit);
    _gps_velD_diff_filt = vz_diff * filter_coef + _gps_velD_diff_filt * (1.f - filter_coef);

    _gps_check_fail_status.flags.vspeed = (fabsf(_gps_velD_diff_filt) > _params.req_vdrift);

} else {
    // reset
    _gps_velD_diff_filt = 0.f;
    _gps_check_fail_status.flags.vspeed = false;
}

Code Quality Assessment

1. Logic Improvement:

   • The updated code introduces a conditional check to ensure that the filter is initialized and either vertical velocity aiding, vertical position aiding is active, or the vehicle is at rest before performing the GPS vspeed check.
   • This prevents unnecessary checks and potential false positives when the conditions are not met.

2. Code Readability:

   • The new conditional block is well-structured and easy to understand.
   • The use of descriptive variable names (vz_diff, vz_diff_limit) enhances readability.
   • The reset logic for _gps_velD_diff_filt and _gps_check_fail_status.flags.vspeed is clear and ensures that these values are appropriately managed when the conditions are not met.

3. Robustness:

   • By adding these checks, the code becomes more robust against scenarios where GPS and EKF vertical velocities might have discrepancies, thus preventing potential fusion failures.
   • The reset mechanism ensures that stale or invalid data does not affect subsequent checks.

4. Performance:

   • The additional conditional checks introduce minimal overhead but significantly enhance the reliability of the GPS vspeed check logic.
   • The use of math::constrain and filtering operations remains efficient.

5. Potential Issues:

   • Daniel Agar's comment highlights a potential interaction where discrepancies between GPS vz and EKF vz could stop all GPS fusion. This update addresses this concern by ensuring checks are only performed under valid conditions.

Conclusion

The changes in PR #23315 improve the stability and accuracy of the PX4 Autopilot's EKF2 module by ensuring that GPS vspeed checks are only performed when valid conditions are met. The code quality is high, with clear logic, good readability, enhanced robustness, and minimal performance impact. This update effectively addresses the potential issue raised by Daniel Agar, making it a valuable improvement to the system.

Aggregate for risks

Notable Risks

Continuous Integration (CI) Failures Due to VTOL SITL Tests

Severity: High (3/3)

Rationale

The failure of VTOL SITL tests on every pull request is a critical issue that disrupts the CI process, delaying development and integration of new features.

• Evidence: Issue #23275 details that the RTL direct rally without approaches forced test is failing consistently on every PR.
• Reasoning: Continuous integration failures can halt the development pipeline, preventing new code from being tested and merged, which can significantly slow down project progress.

Next Steps

• Assign a dedicated team to investigate and resolve the root cause of the VTOL SITL test failures.
• Implement temporary workarounds or disable the failing test if necessary to unblock the CI pipeline while a permanent fix is developed.

Decline in Team Velocity

Severity: Medium (2/3)

Rationale

There is evidence of multiple PRs being left open without resolution, indicating a potential decline in team velocity.

• Evidence: Multiple PRs such as #23236, #23233, #23229, #23228, and #23227 have been open for several days without resolution.
• Reasoning: While not critical, the accumulation of unresolved PRs can slow down development progress and indicate potential bottlenecks in the review process.

Next Steps

• Assign dedicated reviewers to address the backlog of open PRs.
• Implement stricter timelines for PR reviews and merges to ensure timely progress.

Prolonged Disagreement on Gimbal Control Logic

Severity: Medium (2/3)

Rationale

The changes in PR #23236 regarding gimbal control logic adjustments suggest potential prolonged disagreements or complexities in achieving consensus on control mechanisms.

• Evidence: The detailed changes in gimbal control logic and the need for extensive testing across different scenarios indicate potential areas of disagreement or complexity.
• Reasoning: Disagreements or complexities in core control logic can delay feature releases and affect overall project stability.

Next Steps

• Facilitate discussions among key stakeholders to reach a consensus on gimbal control logic.
• Conduct thorough testing and gather feedback from users to validate the changes.

Ambiguous Specifications for EKF2 Enhancements

Severity: Medium (2/3)

Rationale

The recent updates to EKF2 modules such as innovation sequence monitoring (#23233) and mag spikes preflight errors (#23229) indicate ambiguous specifications that may lead to implementation challenges.

• Evidence: The issues and PRs related to EKF2 enhancements involve complex algorithms and state estimation logic, which may not be clearly defined.
• Reasoning: Ambiguous specifications can lead to multiple rewrites and delays in achieving stable implementations.

Next Steps

• Clarify specifications and acceptance criteria for EKF2 enhancements.
• Engage domain experts to review and refine the implementation details.

Deployment Failures Due to Build Process Issues

Severity: Medium (2/3)

Rationale

Recent changes to the build process, including fixes for bootloader targets (#23234) and symforce cmake code generation targets (#23220), suggest ongoing deployment failures.

• Evidence: Multiple issues related to build process improvements indicate potential deployment failures or challenges.
• Reasoning: Consistent deployment failures can hinder development progress and affect the reliability of new releases.

Next Steps

• Conduct a comprehensive review of the build process to identify and address recurring issues.
• Implement automated testing and validation steps to catch build failures early in the development cycle.
