mjb/altos, branch 1.0.9.2

altosui: Deal with missing state transitions in FlightStats window

2011-10-09T17:09:25+00:00

Any missing start/end times are pinned to the end of the flight. Signed-off-by: Keith Packard

altosui: Deal with telem data that goes backwards in time

2011-10-09T17:09:11+00:00

The new telemetry stuff can send packets with older timestamps, so sort telem packets read from disk to create an in-order record of the flight. Signed-off-by: Keith Packard

altos: Respond to telemetry rate changes immediately

2011-10-09T16:21:56+00:00

Instead of waiting for the previous telemetry interval to expire, immediately switch to the new telemetry rate. This will provide more telemetry data early in the boost. Signed-off-by: Keith Packard

altos: Improve TM v1.0 apogee estimate

2011-10-09T04:23:16+00:00

v1.0 boards have noisy accelerometer data caused by interactions between RF transmission and the accelerometer measurements; this noise generates a negative bias in the accelerometer readings. The net effect is that the estimated speed is lower than the actual speed, causing early an apogee estimate. By increasing the sigma value for accelerometer data, the kalman filter 'trusts' the acceleration data less, putting more weight on the barometer data. This causes the estimated time of apogee to be closer to the correct value. This reduces the response to changes in acceleration. This new value is applied solely to TeleMetrum v1.0 boards. v1.1 boards correct for this error, and hence can use the correct sigma value for the accelerometer. Signed-off-by: Keith Packard

Bump to 1.0.9.2

2011-10-09T03:31:34+00:00

(1.1 RC 2). Flown at Oktoberfest 2011 on 10/09/2011 (we hope) Signed-off-by: Keith Packard

altosui: Remove igniter voltages from chart.

2011-10-08T22:07:57+00:00

These are just annoying; when we add the ability to turn stuff on/off on the fly, we can add them to the list of available items. Signed-off-by: Keith Packard

altos: Ignore ejection bumps when doing boost re-detect

2011-10-08T17:59:34+00:00

An ejection charge looks an awful lot like an extra (really small) motor burn. Ignore them by averaging the acceleration during fast/coast using a /64 exponential decay filter. Signed-off-by: Keith Packard

ao-telem: Add new program to convert telem data to ascii

2011-10-08T17:50:24+00:00

This reads telem files and displays them in ascii form. It's not done, and it's not documented, but it's a start. Signed-off-by: Keith Packard

altosui: Allow for multiple instances of each state in the graph

2011-10-08T17:46:38+00:00

With the new boost re-detect code, we can get multiple instances of boost/fast/coast, so make sure each are displayed in the graph. Signed-off-by: Keith Packard

altosui: Max acceleration across boost instead of all ascent

2011-10-08T17:43:37+00:00

This ignores ejection bumps, making the max acceleration far more useful. Signed-off-by: Keith Packard
