7 Version 1.0 is a major release, adding support for the TeleMini
8 device and lots of new AltosUI features
11 AltOS Firmware Changes
14 Add TeleMini v1.0 support. Firmware images for TeleMini are
15 included in AltOS releases.
18 Change telemetry to be encoded in multiple 32-byte packets. This
19 enables support for TeleMini and other devices without requiring
20 further updates to the TeleDongle firmware.
23 Support operation of TeleMetrum with the antenna pointing
24 aft. Previous firmware versions required the antenna to be
25 pointing upwards, now there is a configuration option allowing
26 the antenna to point aft, to aid installation in some airframes.
29 Arbitrary frequency selection. The radios in Altus Metrum
30 devices can be programmed to a wide range of frequencies, so
31 instead of limiting devices to 10 pre-selected 'channels', the
32 new firmware allows the user to choose any frequency in the
33 70cm band. Note that the RF matching circuit on the boards is
34 tuned for around 435MHz, so frequencies far from that may
35 reduce the available range.
38 Kalman-filter based flight-tracking. The model based sensor
39 fusion approach of a Kalman filter means that AltOS now
40 computes apogee much more accurately than before, generally
41 within a fraction of a second. In addition, this approach
42 allows the baro-only TeleMini device to correctly identify
43 Mach transitions, avoiding the error-prone selection of a Mach
52 Wait for altimeter when using packet mode. Instead of quicly
53 timing out when trying to initialize a packet mode
54 configuration connection, AltosUI now waits indefinitely for
55 the remote device to appear, providing a cancel button should
56 the user get bored. This is necessary as the TeleMini can only
57 be placed in "Idle" mode if AltosUI is polling it.
60 Add main/apogee voltage graphs to the data plot. This provides
61 a visual indication if the igniters fail before being fired.
64 Scan for altimeter devices by watching the defined telemetry
65 frequencies. This avoids the problem of remembering what
66 frequency a device was configured to use, which is especially
67 important with TeleMini which does not include a USB connection.
70 Monitor altimeter state in "Idle" mode. This provides much of
71 the information presented in the "Pad" dialog from the Monitor
72 Flight command, monitoring the igniters, battery and GPS
73 status withing requiring the flight computer to be armed and
77 Pre-load map images from home. For those launch sites which
78 don't provide free Wi-Fi, this allows you to download the
79 necessary satellite images given the location of the launch
80 site. A list of known launch sites is maintained at
81 altusmetrum.org which AltosUI downloads to populate a menu; if
82 you've got a launch site not on that list, please send the
83 name of it, latitude and longitude along with a link to the
84 web site of the controlling club to the altusmetrum mailing list.
87 Flight statistics are now displayed in the Graph data
88 window. These include max height/speed/accel, average descent
89 rates and a few other bits of information. The Graph Data
90 window can now be reached from the 'Landed' tab in the Monitor
91 Flight window so you can immediately see the results of a
