Version 1.0 is a major release, adding support for the TeleMini
device and lots of new AltosUI features
</para>
<para>
AltOS Firmware Changes
<itemizedlist>
<listitem>
Add TeleMini v1.0 support. Firmware images for TeleMini are
included in AltOS releases.
</listitem>
<listitem>
Change telemetry to be encoded in multiple 32-byte packets. This
enables support for TeleMini and other devices without requiring
further updates to the TeleDongle firmware.
</listitem>
<listitem>
Support operation of TeleMetrum with the antenna pointing
aft. Previous firmware versions required the antenna to be
pointing upwards, now there is a configuration option allowing
the antenna to point aft, to aid installation in some airframes.
</listitem>
<listitem>
Ability to disable telemetry. For airframes where an antenna
just isn't possible, or where radio transmissions might cause
trouble with other electronics, there's a configuration option
to disable all telemetry. Note that the board will still
enable packet mode in idle mode.
</listitem>
<listitem>
Arbitrary frequency selection. The radios in Altus Metrum
devices can be programmed to a wide range of frequencies, so
instead of limiting devices to 10 pre-selected 'channels', the
new firmware allows the user to choose any frequency in the
70cm band. Note that the RF matching circuit on the boards is
tuned for around 435MHz, so frequencies far from that may
reduce the available range.
</listitem>
<listitem>
Kalman-filter based flight-tracking. The model based sensor
fusion approach of a Kalman filter means that AltOS now
computes apogee much more accurately than before, generally
within a fraction of a second. In addition, this approach
allows the baro-only TeleMini device to correctly identify
Mach transitions, avoiding the error-prone selection of a Mach
delay.
</listitem>
</itemizedlist>
</para>
<para>
AltosUI Changes
<itemizedlist>
<listitem>
Wait for altimeter when using packet mode. Instead of quicly
timing out when trying to initialize a packet mode
configuration connection, AltosUI now waits indefinitely for
the remote device to appear, providing a cancel button should
the user get bored. This is necessary as the TeleMini can only
be placed in "Idle" mode if AltosUI is polling it.
</listitem>
<listitem>
Add main/apogee voltage graphs to the data plot. This provides
a visual indication if the igniters fail before being fired.
</listitem>
<listitem>
Scan for altimeter devices by watching the defined telemetry
frequencies. This avoids the problem of remembering what
frequency a device was configured to use, which is especially
important with TeleMini which does not include a USB connection.
</listitem>
<listitem>
Monitor altimeter state in "Idle" mode. This provides much of
the information presented in the "Pad" dialog from the Monitor
Flight command, monitoring the igniters, battery and GPS
status withing requiring the flight computer to be armed and
ready for flight.
</listitem>
<listitem>
Pre-load map images from home. For those launch sites which
don't provide free Wi-Fi, this allows you to download the
necessary satellite images given the location of the launch
site. A list of known launch sites is maintained at
altusmetrum.org which AltosUI downloads to populate a menu; if
you've got a launch site not on that list, please send the
name of it, latitude and longitude along with a link to the
web site of the controlling club to the altusmetrum mailing list.
</listitem>
<listitem>
Flight statistics are now displayed in the Graph data
window. These include max height/speed/accel, average descent
rates and a few other bits of information. The Graph Data
window can now be reached from the 'Landed' tab in the Monitor
Flight window so you can immediately see the results of a
flight.
