Paul Riseborough	fed4a9bc5a	EKF: add vertical position derivative output ... Add calculation of a vertical position derivative to the output predictor. This will have degraded tracking relative to the EKF states, but the velocity will be closer to the first derivative of the position and reduce the effect inertial prediction errors on control loops that are operating in a pure velocity feedback mode. Move calculation of IMU offset angular rate correction out of velocity accessor and into output predictor. Provide separate accessor for vertical position derivative.	2017-06-12 10:45:46 +10:00

Lucas De Marchi	2240eb6b4f	Move __STDC_FORMAT_MACROS to build system (#174) ... __STDC_FORMAT_MACROS changes the behavior of inttypes.h to allow defining format macros for printf-like functions. It needs to be defined before any include is done, otherwise due to include chains and header guards it may not take effect. Instead of defining it everywhere it is used, let the PX4 build system to deal with it.	2016-07-10 16:29:51 +02:00
Paul Riseborough	30917430e2	EKF: inline ring buffer functions used repeatedly ... These functions get called 30 times each per output prediction cycle	2016-05-23 07:43:59 +10:00
Paul Riseborough	62c6d40f1f	EKF: Add methods to ring buffer to access specific indices	2016-04-22 08:21:36 +10:00
Paul Riseborough	a352c2f4e3	EKF: Fix posix build error ... Memset cannot be used on a class like this. Setting the time elements to zero achieves the desired result.	2016-04-05 18:57:21 -07:00
Paul Riseborough	430d4b1cf8	EKF: ensure data in buffers is zero at startup	2016-04-05 22:23:37 +02:00
Roman	ce0ddc0207	-added comments ... -removed unused print functions -removed false _imu_time_last variable (correct is _time_last_imu)	2016-02-14 09:49:26 +01:00
