= Release Notes for Version 1.0.1

:doctype: article
|
|
|
|
Version 1.0.1 is a major release, adding support for the
|
|
TeleMini device and lots of new AltosUI features
|
|
|
|
== AltOS
|
|
|
|
AltOS New Features
|
|
|
|
* Add TeleMini v1.0 support.
|
|
|
|
* 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.
|
|
|
|
* 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 the radio link in idle mode.
|
|
|
|
* 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.
|
|
|
|
|
|
AltOS Fixes
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
|
|
== AltosUI Application
|
|
|
|
AltosUI New Features
|
|
|
|
* Add main/apogee voltage graphs to the data
|
|
plot. This provides a visual indication if the
|
|
igniters fail before being fired.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
AltosUI Changes
|
|
|
|
* 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.
