Welcome to the Altus Metrum community! Our circuits and software reflect
our passion for both hobby rocketry and Free Software. We hope their
capabilities and performance will delight you in every way, but by
as standard features, and a "companion interface" that will
support optional capabilities in the future.
</p><p>
- The newest device is TeleMini, a dual deploy altimeter with
+ Our second device was TeleMini, a dual deploy altimeter with
radio telemetry and radio direction finding. This device is only
13mm by 38mm (½ inch by 1½ inches) and can fit easily in an 18mm
air-frame.
</p><p>
- Complementing TeleMetrum and TeleMini is TeleDongle, a USB to RF
- interface for communicating with the altimeters. Combined with your
- choice of antenna and
- notebook computer, TeleDongle and our associated user interface software
- form a complete ground station capable of logging and displaying in-flight
- telemetry, aiding rocket recovery, then processing and archiving flight
+ TeleDongle was our first ground station, providing a USB to RF
+ interfaces for communicating with the altimeters. Combined with
+ your choice of antenna and notebook computer, TeleDongle and our
+ associated user interface software form a complete ground
+ station capable of logging and displaying in-flight telemetry,
+ aiding rocket recovery, then processing and archiving flight
data for analysis and review.
+ </p><p>
+ For a slightly more portable ground station experience that also
+ provides direct rocket recovery support, TeleBT offers flight
+ monitoring and data logging using a Bluetooth connection between
+ the receiver and an Android device that has the Altos Droid
+ application installed from the Google Play store.
</p><p>
More products will be added to the Altus Metrum family over time, and
we currently envision that this will be a single, comprehensive manual
for the entire product family.

will deliver impressive results. However, as with all electronic
As with all other rocketry electronics, Altus Metrum altimeters must

TeleMetrum is a 1 inch by 2.75 inch circuit board. It was designed to
fit inside coupler for 29mm air-frame tubing, but using it in a tube that
small in diameter may require some creativity in mounting and wiring
power on/off, and two pairs of wires connecting e-matches for the
apogee and main ejection charges. All Altus Metrum products are
designed for use with single-cell batteries with 3.7 volts nominal.
+ </p><p>
+ The battery connectors are a standard 2-pin JST connector and
+ match batteries sold by Spark Fun. These batteries are
+ single-cell Lithium Polymer batteries that nominally provide 3.7
+ volts. Other vendors sell similar batteries for RC aircraft
+ using mating connectors, however the polarity for those is
+ generally reversed from the batteries used by Altus Metrum
+ products. In particular, the Tenergy batteries supplied for use
+ in Featherweight flight computers are not compatible with Altus
+ Metrum flight computers or battery chargers. <span class="emphasis"><em>Check
+ polarity and voltage before connecting any battery not purchased
+ from Altus Metrum or Spark Fun.</em></span>
</p><p>
By default, we use the unregulated output of the Li-Po battery directly
to fire ejection charges. This works marvelously with standard
connection, and, on TeleMetrum, you can unplug the integrated GPS
antenna and select an appropriate off-board GPS antenna with
cable terminating in a U.FL connector.

Firmware Modes </h2></div></div></div><p>
The AltOS firmware build for the altimeters has two
fundamental modes, "idle" and "flight". Which of these modes
the firmware operates in is determined at start up time. For
flashes before launching! For apogee-only or motor eject
flights, do what makes sense.
</p><p>
- If idle mode is entered, you will hear an audible "di-dit" or see
- two short flashes ("I" for idle), and the flight state machine is
- disengaged, thus no ejection charges will fire. The altimeters also
- listen for the radio link when in idle mode for requests sent via
- TeleDongle. Commands can be issued to a TeleMetrum in idle mode
- over either
- USB or the radio link equivalently. TeleMini only has the radio link.
- Idle mode is useful for configuring the altimeter, for extracting data
- from the on-board storage chip after flight, and for ground testing

TeleMetrum includes a complete GPS receiver. A complete explanation
of how GPS works is beyond the scope of this manual, but the bottom
line is that the TeleMetrum GPS receiver needs to lock onto at least

long before igniter installation and return to the flight line are
complete.

Configuring an Altus Metrum altimeter for flight is very
simple. Even on our baro-only TeleMini board, the use of a Kalman
filter means there is no need to set a "mach delay". The few
configurable parameters can all be set using AltosUI over USB or
or radio link via TeleDongle.

Altus Metrum boards support radio frequencies in the 70cm
band. By default, the configuration interface provides a
list of 10 "standard" frequencies in 100kHz channels starting at
frequency will be used to avoid interference. And of course, both
altimeter and TeleDongle must be configured to the same
frequency to successfully communicate with each other.

Apogee delay is the number of seconds after the altimeter detects flight
apogee that the drogue charge should be fired. In most cases, this
should be left at the default of 0. However, if you are flying
or 3 seconds later to avoid any chance of both charges
firing simultaneously. We've flown several air-frames this
way quite happily, including Keith's successful L3 cert.

By default, the altimeter will fire the main deployment charge at an
elevation of 250 meters (about 820 feet) above ground. We think this
is a good elevation for most air-frames, but feel free to change this
deployment elevation for the backup altimeter to be something lower
than the primary so that both pyrotechnic charges don't fire
simultaneously.

This configures the frequency to use for both telemetry and
packet command mode. Set this before starting any operation
involving packet command mode so that it will use the right
frequency. Telemetry monitoring mode also provides a menu to
change the frequency, and that menu also sets the same Java

The radios in every Altus Metrum device are calibrated at the
factory to ensure that they transmit and receive on the
specified frequency. To change a TeleDongle's calibration,
you must reprogram the unit completely, so this entry simply
shows the current value and doesn't allow any changes.

This activates the igniter circuits in TeleMetrum to help test
recovery systems deployment. Because this command can operate
over the Packet Command Link, you can prepare the rocket as
you have 10 seconds to press the 'Fire' button or the system
will deactivate, at which point you start over again at
selecting the desired igniter.

This listens for telemetry packets on all of the configured
frequencies, displaying information about each device it
receives a packet from. You can select which of the three
telemetry formats should be tried; by default, it only listens
for the standard telemetry packets used in v1.0 and later

Before heading out to a new launch site, you can use this to
load satellite images in case you don't have internet
connectivity at the site. This loads a fairly large area
once, so if you load more than one launch site, you may get
some gray areas in the map which indicate that Google is tired
of sending data to you. Try again later.

Building high-power rockets that fly safely is hard enough. Mix
in some sophisticated electronics and a bunch of radio energy
and oftentimes you find few perfect solutions. This chapter
contains some suggestions about how to install Altus Metrum
products into the rocket air-frame, including how to safely and
reliably mix a variety of electronics into the same air-frame.
- </p><div class="section"

><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="idp3940432"></a>1. Mounting the Altimeter</h2></div></div></div><p>
The first consideration is to ensure that the altimeter is
securely fastened to the air-frame. For TeleMetrum, we use
nylon standoffs and nylon screws; they're good to at least 50G
Watch for any metal touching components on the
board. Shorting out connections on the bottom of the board
can cause the altimeter to fail during flight.

><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="idp3942768"></a>2. Dealing with the Antenna</h2></div></div></div><p>
The antenna supplied is just a piece of solid, insulated,
wire. If it gets damaged or broken, it can be easily
replaced. It should be kept straight and not cut; bending or
SMA connector, and then run 50Ω coax from the board to the
antenna. Building a remote antenna is beyond the scope of this
manual.

The GPS antenna and receiver in TeleMetrum are highly
sensitive and normally have no trouble tracking enough
satellites to provide accurate position information for
antenna as that's covered with a ground plane. But, keep
wires and metal out from above the patch antenna.

Any altimeter will generate RFI; the digital circuits use
high-frequency clocks that spray radio interference across a
wide band. Altus Metrum altimeters generate intentional radio
Voltages are induced when radio frequency energy is
transmitted from one circuit to another. Here are things that
influence the induced voltage and current:

simple ratio of that length; essentially any multiple of 1/4
of the wavelength (17.5cm).

><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="idp3953208"></a>5. The Barometric Sensor</h2></div></div></div><p>
Altusmetrum altimeters measure altitude with a barometric
sensor, essentially measuring the amount of air above the
rocket to figure out how high it is. A large number of
chemical damage from the products of APCP or BP combustion, so
make sure the ebay is carefully sealed from any compartment
which contains ejection charges or motors.

><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="idp3955048"></a>6. Ground Testing</h2></div></div></div><p>
The most important aspect of any installation is careful
ground testing. Bringing an air-frame up to the LCO table which
hasn't been ground tested can lead to delays or ejection
interface through a TeleDongle to command each charge to
fire. Make sure the charge is sufficient to robustly separate
the air-frame and deploy the recovery system.

The big concept to understand is that you have to use a
TeleDongle as a programmer to update a TeleMetrum or TeleMini,
and a TeleMetrum or other TeleDongle to program the TeleDongle
version from <a class="ulink" href="http://www.altusmetrum.org/AltOS/" target="_top">http://www.altusmetrum.org/AltOS/</a>.
</p><p>
We recommend updating the altimeter first, before updating TeleDongle.

TeleMetrum seems to shut off when disconnected from the
computer. Make sure the battery is adequately charged. Remember the
unit will pull more power than the USB port can deliver before the
data after physically retrieving your altimeter. Make sure to save
the on-board data after each flight; while the TeleMetrum can store
multiple flights, you never know when you'll lose the altimeter...

There are only two calibrations required for a TeleMetrum board, and
only one for TeleDongle and TeleMini. All boards are shipped from
the factory pre-calibrated, but the procedures are documented here
AltosUI, you must connect to the board with a serial terminal program
and interact directly with the on-board command interpreter to effect
calibration.

The radio frequency is synthesized from a clock based on the 48 MHz
crystal on the board. The actual frequency of this oscillator
must be measured to generate a calibration constant. While our
radio frequency is reset to the default 434.550 Mhz. If you want
to use another frequency, you will have to set that again after
calibration is completed.

The TeleMetrum accelerometer we use has its own 5 volt power
supply and
the output must be passed through a resistive voltage divider to match
to the index post on the 4-pin end of the programming cable, and
power up the board. It should come up in 'idle mode' (two beeps),
allowing a re-cal.
