1 = Release Notes for Version 1.0.1
5 Version 1.0.1 is a major release, adding support for the
6 TeleMini device and lots of new AltosUI features
12 * Add TeleMini v1.0 support.
14 * Support operation of TeleMetrum with the antenna pointing
15 aft. Previous firmware versions required the antenna to be
16 pointing upwards, now there is a configuration option
17 allowing the antenna to point aft, to aid installation in
20 * Ability to disable telemetry. For airframes where an antenna
21 just isn't possible, or where radio transmissions might
22 cause trouble with other electronics, there's a
23 configuration option to disable all telemetry. Note that the
24 board will still enable the radio link in idle mode.
26 * Arbitrary frequency selection. The radios in Altus Metrum
27 devices can be programmed to a wide range of frequencies, so
28 instead of limiting devices to 10 pre-selected 'channels',
29 the new firmware allows the user to choose any frequency in
30 the 70cm band. Note that the RF matching circuit on the
31 boards is tuned for around 435MHz, so frequencies far from
32 that may reduce the available range.
37 * Change telemetry to be encoded in multiple 32-byte
38 packets. This enables support for TeleMini and other devices
39 without requiring further updates to the TeleDongle
42 * Kalman-filter based flight-tracking. The model based sensor
43 fusion approach of a Kalman filter means that AltOS now
44 computes apogee much more accurately than before, generally
45 within a fraction of a second. In addition, this approach
46 allows the baro-only TeleMini device to correctly identify
47 Mach transitions, avoiding the error-prone selection of a
51 == AltosUI Application
55 * Add main/apogee voltage graphs to the data
56 plot. This provides a visual indication if the
57 igniters fail before being fired.
59 * Scan for altimeter devices by watching the defined
60 telemetry frequencies. This avoids the problem of
61 remembering what frequency a device was configured
62 to use, which is especially important with TeleMini
63 which does not include a USB connection.
65 * Monitor altimeter state in "Idle" mode. This
66 provides much of the information presented in the
67 "Pad" dialog from the Monitor Flight command,
68 monitoring the igniters, battery and GPS status
69 withing requiring the flight computer to be armed
73 * Pre-load map images from home. For those launch
74 sites which don't provide free Wi-Fi, this allows
75 you to download the necessary satellite images
76 given the location of the launch site. A list of
77 known launch sites is maintained at altusmetrum.org
78 which AltosUI downloads to populate a menu; if
79 you've got a launch site not on that list, please
80 send the name of it, latitude and longitude along
81 with a link to the web site of the controlling club
82 to the altusmetrum mailing list.
84 * Flight statistics are now displayed in the Graph
85 data window. These include max height/speed/accel,
86 average descent rates and a few other bits of
87 information. The Graph Data window can now be
88 reached from the 'Landed' tab in the Monitor Flight
89 window so you can immediately see the results of a
94 * Wait for altimeter when using packet mode. Instead
95 of quicly timing out when trying to initialize a
96 packet mode configuration connection, AltosUI now
97 waits indefinitely for the remote device to appear,
98 providing a cancel button should the user get
99 bored. This is necessary as the TeleMini can only be
100 placed in "Idle" mode if AltosUI is polling it.
