= Release Notes for Version 1.8.1

|
|
|
|
Version 1.8.1 includes an important bug fix for Apogee Lockout
|
|
operation in all flight computers. Anyone using this option
|
|
must update firmware.
|
|
|
|
This release also contains a change in how flight computers
|
|
with accelerometers deal with speeds around and above Mach
|
|
1. In previous versions, the flight computer would completely
|
|
disregard the barometric sensor above 330m/s (around Mach
|
|
1). Now, the data from the barometric sensor is reduced in
|
|
effect without ever going away entirely. This prevents early
|
|
drogue deployment for flights which spend considerable time
|
|
above Mach 1.
|
|
|
|
1.8.1 also contains a couple of minor fixes for AltosUI when
|
|
analyzing saved data files.

AltOS Bug Fixes
|
|
|
|
* Handle time value wrapping in Apogee Lockout
|
|
correctly. Without this, apogee lockout would sometimes
|
|
prevent any drogue charge from firing.
|
|
|
|
* Change Kalman filter on flight computers with accelerometer
|
|
to continue using the barometric sensor even at high speeds
|
|
to avoid unintentional drogue deployment during
|
|
deceleration.
|
|
|
|
== AltosUI and TeleGPS Applications
|
|
|
|
AltosUI New Features
|
|
|
|
* Add new 'Huge' font size to make text even bigger on high
|
|
resolution monitors.

AltosUI Bug Fixes
|
|
|
|
* Prevent some crashes when reading older saved flight data
|
|
for graphing or KML export.
|
|
|
|
* Load frequency preference at startup. The loading code was
|
|
broken, so you'd see only the default frequencies.
