10 Add TeleMini v1.0 support.
11 </li><li class="listitem">
12 Support operation of TeleMetrum with the antenna pointing
13 aft. Previous firmware versions required the antenna to be
14 pointing upwards, now there is a configuration option
15 allowing the antenna to point aft, to aid installation in

18 Ability to disable telemetry. For airframes where an antenna
19 just isn’t possible, or where radio transmissions might
20 cause trouble with other electronics, there’s a
21 configuration option to disable all telemetry. Note that the
22 board will still enable the radio link in idle mode.
23 </li><li class="listitem">
24 Arbitrary frequency selection. The radios in Altus Metrum
25 devices can be programmed to a wide range of frequencies, so
26 instead of limiting devices to 10 pre-selected <span class="emphasis"><em>channels</em></span>,
27 the new firmware allows the user to choose any frequency in
28 the 70cm band. Note that the RF matching circuit on the
29 boards is tuned for around 435MHz, so frequencies far from
30 that may reduce the available range.

32 Change telemetry to be encoded in multiple 32-byte
33 packets. This enables support for TeleMini and other devices
34 without requiring further updates to the TeleDongle
36 </li><li class="listitem">
37 Kalman-filter based flight-tracking. The model based sensor
38 fusion approach of a Kalman filter means that AltOS now
39 computes apogee much more accurately than before, generally
40 within a fraction of a second. In addition, this approach
41 allows the baro-only TeleMini device to correctly identify
42 Mach transitions, avoiding the error-prone selection of a

45 Add main/apogee voltage graphs to the data
46 plot. This provides a visual indication if the
47 igniters fail before being fired.
48 </li><li class="listitem">
49 Scan for altimeter devices by watching the defined
50 telemetry frequencies. This avoids the problem of
51 remembering what frequency a device was configured
52 to use, which is especially important with TeleMini
53 which does not include a USB connection.
54 </li><li class="listitem">
55 Monitor altimeter state in "Idle" mode. This
56 provides much of the information presented in the
57 "Pad" dialog from the Monitor Flight command,
58 monitoring the igniters, battery and GPS status
59 withing requiring the flight computer to be armed
61 </li><li class="listitem">
62 Pre-load map images from home. For those launch
63 sites which don’t provide free Wi-Fi, this allows
64 you to download the necessary satellite images
65 given the location of the launch site. A list of
66 known launch sites is maintained at altusmetrum.org
67 which AltosUI downloads to populate a menu; if
68 you’ve got a launch site not on that list, please
69 send the name of it, latitude and longitude along
70 with a link to the web site of the controlling club
71 to the altusmetrum mailing list.

73 Flight statistics are now displayed in the Graph
74 data window. These include max height/speed/accel,
75 average descent rates and a few other bits of
76 information. The Graph Data window can now be
77 reached from the <span class="emphasis"><em>Landed</em></span> tab in the Monitor Flight

81 Wait for altimeter when using packet mode. Instead
82 of quicly timing out when trying to initialize a
83 packet mode configuration connection, AltosUI now
84 waits indefinitely for the remote device to appear,
85 providing a cancel button should the user get
86 bored. This is necessary as the TeleMini can only be
87 placed in "Idle" mode if AltosUI is polling it.
