3 AltOS is the name of Keith's firmware "operating system" for
4 [TeleMetrum](../TeleMetrum/) and [TeleDongle](../TeleDongle/).
6 In addition to the firmware for [TeleMetrum](../TeleMetrum) and
7 [TeleDongle](../TeleDongle) boards, the AltOS source tree also
8 includes AltosUI, which provides for flight monitoring, post-flight
9 analysis, device configuration and firmware updating. AltosUI runs on
10 Linux, Mac OS X and Windows. It's written in [Java](http://java.com)
11 and offers the same functionality and interface on all three
12 platforms. A small platform-specific library communicates with the USB
13 interface on the Altus Metrum devices.
15 There are also Linux-specific tools that provide lower level access to
16 the devices which are useful for developing firmware for the devices.
18 The firmware and associated software are licensed [GPL version
19 2](http://www.gnu.org/licenses/old-licenses/gpl-2.0.html)
21 ## Available Versions ##
23 There is a single manual for all Altus Metrum products, which is available
24 in [html](doc/altusmetrum.html) and [pdf](doc/altusmetrum.pdf) formats.
26 [[!inline pages="./releases/* and !*/Discussion and !*.bz2 and !*.zip and !*.exe" show="10" rss="no" raw="yes" ]]
28 The latest source, which may include unreleased work in progress, is always
29 available from [git.gag.com](http://git.gag.com)
30 in the project [fw/altos](http://git.gag.com/?p=fw/altos;a=summary).
32 If you need to debug code on an Altus Metrum product, you may want our special
33 version of SDCC containing a highly modified sdcdb with support for the cc1111
34 debugging interface, which you can find on [git.gag.com](http://git.gag.com)
35 in the project [fw/sdcc](http://git.gag.com/?p=fw/sdcc;a=summary). This is
36 not necessary if you just want to rebuild AltOS and use it.
38 ### Version 0.9.2 Features ###
40 Version 0.9.2 is an AltosUI bug-fix release, with no firmware changes.
42 * Fix plotting problems due to missing file in the Mac OS install image.
44 * Always read whole eeprom blocks, mark empty records invalid, display
45 parsing errors to user.
47 * Add software version to Configure AltosUI dialog
49 ### Version 0.9 Features ###
51 Version 0.9 adds a few new firmware features and accompanying AltosUI
52 changes, along with new hardware support.
54 * Support for TeleMetrum v1.1 hardware. Sources for the flash memory
55 part used in v1.0 dried up, so v1.1 uses a different part which
56 required a new driver and support for explicit flight log erasing.
58 * Multiple flight log support. This stores more than one flight log
59 in the on-board flash memory. It also requires the user to
60 explicitly erase flights so that you won't lose flight logs just
61 because you fly the same board twice in one day.
63 * Telemetry support for devices with serial number >= 256. Previous
64 versions used a telemetry packet format that provided only 8 bits
65 for the device serial number. This change requires that both ends
66 of the telemetry link be running the 0.9 firmware or they will not
69 ### Version 0.8 Features ###
71 Version 0.8 offers a major upgrade in the AltosUI
72 interface. Significant new features include:
74 * Post-flight graphing tool. This lets you explore the behaviour of
75 your rocket after flight with a scroll-able and zoom-able chart
76 showing the altitude, speed and acceleration of the airframe along
77 with events recorded by the flight computer. You can export graphs
78 to PNG files, or print them directly.
80 * Real-time moving map which overlays the in-progress flight on
81 satellite imagery fetched from
82 [Google Maps](http://maps.google.com). This lets you see in pictures
83 where your rocket has landed, allowing you to plan recovery
84 activities more accurately.
86 * Wireless recovery system testing. Prep your rocket for flight and test
87 fire the deployment charges to make sure things work as
88 expected. All without threading wires through holes in your
91 * Optimized flight status displays. Each flight state now has it's own
92 custom 'tab' in the flight monitoring window so you can focus on the
93 most important details. Pre-flight, the system shows a set of
94 red/green status indicators for battery voltage, apogee/main igniter
95 continutity and GPS reception. Wait until they're all green and your
96 rocket is ready for flight. There are also tabs for ascent, descent
97 and landing along with the original tabular view of the data.
99 * Monitor multiple flights simultaneously. If you have more than one
100 TeleDongle, you can monitor a flight with each one on the same
103 * Automatic flight monitoring at startup. Plug TeleDongle into the
104 machine before starting AltosUI and it will automatically connect to
105 it and prepare to monitor a flight.
107 * Exports Google Earth flight tracks. Using the Keyhole Markup
108 Language (.kml) file format, this provides a 3D view of your rocket
109 flight through the Google Earth program.
111 ### Version 0.7.1 Features ###
113 Version 0.7.1 is the first release containing our new cross-platform Java-based user interface. AltosUI can:
115 * Receive and log telemetry from a connected TeleDongle device. All data
116 received is saved to log files named with the current date and the connected
117 rocket serial and flight numbers. There is no mode in which telemetry data
120 * Download logged data from TeleMetrum devices, either through a direct USB
121 connection or over the air through a TeleDongle device.
123 * Configure a TeleMetrum device, setting the radio channel, callsign, apogee
124 delay and main deploy height. This can be done through either a USB
125 connection or over a radio link via a TeleDongle device.
127 * Replay a flight in real-time. This takes a saved telemetry log or eeprom
128 download and replays it through the user interface so you can relive your
129 favorite rocket flights.
131 * Reprogram Altus Metrum devices. Using an Altus Metrum device connected via
132 USB, another Altus Metrum device can be reprogrammed using the supplied
133 programming cable between the two devices.
135 * Export Flight data to a comma-separated-values file. This takes either
136 telemetry or on-board flight data and generates data suitable for use in
137 external applications. All data is exported using standard units so that no
138 device-specific knowledge is needed to handle the data.
140 * Speak to you during the flight. Instead of spending the flight hunched over
141 your laptop looking at the screen, enjoy the view while the computer tells
142 you what’s going on up there. During ascent, you hear the current flight
143 state and altitude information. During descent, you get azimuth, elevation
144 and range information to try and help you find your rocket in the air. Once
145 on the ground, the direction and distance are reported.
147 AltosUI provides all of these features on the three target operating systems,
148 Linux, Mac OS X (version 10.5 or newer) and Windows (XP, Vista or 7). The bulk
149 of the software is written in Java and is built once and tested and delivered
150 on all three target platforms. A tiny ‘shim’ library is built on each system
151 to provide access to the Altus Metrum devices connected over the USB link.
155 Bug reports, feature requests, and planning for AltOS releases happens
156 on the [Altus Metrum Trac Site](http://trac.gag.com/altusmetrum).
158 A number of features are implemented or in process in the sources available
159 in our publicly visible repository that are not part of the current stable
162 * A Kalman-filter based approach to apogee detection using more than just the
163 baro sensor, so that we can safely control apogee ejection on flights to
164 altitudes beyond the range of our baro sensor alone. Unlike the other items
165 on the list, this will be a significant change to the in-rocket TeleMetrum
166 firmware. It may therefore be a while before this becomes part of a stable
169 * Motor characterization. Because TeleMetrum contains a
170 high-resolution, high-frequency accelerometer, it is possible to
171 take the data from that and compute an accurate thrust curve for
174 * Comprehensive PDF and/or HTML -based flight report. Construct a
175 complete report of the flight suitable for publication on the web
176 that includes graphs of the flight and details about motor
179 * Publish flight data to the Altus Metrum web site. This will allow
180 you to share your flight data with others, and let you download
181 flights published by others.
183 There are any number of additions that could be made to this list; feel free
184 to send along ideas that you’ve got. Of course, all of this software is
185 licensed under the GNU General Public License, so you can get the source and
186 hack on it in the comfort of your own home.
188 ## Platform Specific Notes ##
192 If you use [Debian](http://www.debian.org), then a pre-built package for
193 32-bit x86 is currently available here:
195 wget -O - http://altusmetrum.org/apt/altusmetrum.key | apt-key add -
196 wget -O /etc/apt/sources.list.d/altos.list http://altusmetrum.org/apt/altos.list
198 apt-get install altos
200 If you use some other distribution of Linux, then
201 a Linux package of our second-generation Java bits that
202 should run on any distribution with a modern Java version is also
203 available. Unlike the Debian pacakge, which depends on various libraries
204 already part of the Debian distribution, this package includes a "fat" jar
205 file with all of the Java libraries that aren't part of the basic Java runtime
206 environment included, so it should "just work" on any system with
207 Java 6. Development and testing is done with OpenJDK 6, but current
208 downloads from [java.com](http://java.com) should be fine too.
210 If you'd rather build from source, our source tree includes documentation on
211 how to build packages for various
212 Linux systems such as [Arch Linux](http://www.archlinux.org), and the
213 debian/ directory contains all the control
214 files for building the Debian packages on other architectures or derivatives
215 such as [Ubuntu](http://ubuntu.com).
217 Bdale has also created a theme for
218 [GDM](http://projects.gnome.org/gdm/) that he uses on his primary notebook,
220 [Simple Login Manager](http://slim.berlios.de/) that he uses on all of his
221 other machines and which is ideally suited for machines dedicated to AltOS
222 ground station use. It includes a photo of a drag-race between
223 nearly-identical rockets
224 built by Keith and Bdale, that was the first time either of us gave TeleMetrum
225 complete control of a rocket flight without some other backup! See the themes/
226 directory in the source tree (the themes are included in the Debian package).
230 A Mac OS X package that is compatible with versions 10.5 "Leopard" and
231 later (including 10.6 "Snow Leopard") is available. The Mac operating
232 system includes Java, and all Altus Metrum products show up as simple
233 USB serial ports, so this should just work with no additional drivers
234 or other dependency issues. Older versions of the Mac operating
235 system, and even newer versions for PowerPC-based machines, come with
236 Java version 5 or older, which is too old for use with Altus Metrum
237 software. We know of no way to update the Java version other than
238 upgrading to a newer operating system (for Intel based macs) or
239 purchasing new hardware (for PowerPC based macs).
243 Our Windows package is known to work on at least some flavors of XP, Vista, and
244 Windows 7 Enterprise. If you don't already have Java installed,
245 download and install a current Java 6 version from [java.com](http://java.com)
246 first. Then download our installer and run it. Windows already has
247 the required USB serial device driver, and our package should do the right
248 things to bind it to our devices, but if you get a complaint about the device
249 being unrecognized, try pointing to the copy of the telemetrum.inf file
250 included in the package directory manually.
