priseborough 13df6fb1c9 AP_NavEKF : Reduce ripple in estimates that can cause copter motor 'pulsing' 
This patch reduces the level of 5Hz and 10Hz 'pulsing' heard in motors due to GPS and altimeter fusion which cause a small 5Hz and 10Hz ripple on the output under some conditions. Attitude, velocity and position state corrections from GPS, altimeter and magnetometer measurements are applied incrementally in the interval from receiving the measurement to the predicted time of receipt of the next measurement. Averaging of attitude state corrections is not performed during periods of rapid rotation.

Time stamps are now explicitly initialised to the current IMU time to avoid unwanted activation of timeout logic on filter start and the various calls to the hal.scheduler->millis() object have been consolidated.

Unused variables have been removed

How To Get Involved

The ArduPilot project is open source and we encourage participation and code contributions: guidelines for contributors to the ardupilot codebase

We have an active group of Beta Testers especially for ArduCopter to help us find bugs: release procedures

Desired Enhancements and Bugs can be posted to the issues list.

Helping other users with log analysis on diydrones.com and the APM forums is always appreciated:

There is a group of wiki editors as well in case documentation is your thing: ardu-wiki-editors@googlegroups.com

Developer discussions occur on drones-discuss@google-groups.com
