Updated for software version 1.3. Version 1.3 adds support
for TeleMega, TeleMetrum v2.0, TeleMini v2.0 and EasyMini
and fixes bugs in AltosUI and the AltOS firmware.
Updated for software version 0.9. Note that 0.9 represents a
telemetry format change, meaning both ends of a link (TeleMetrum and
TeleDongle) must be updated or communications will fail.

When handled gently and properly installed in an air-frame, they
will deliver impressive results. However, as with all electronic
As with all other rocketry electronics, Altus Metrum altimeters must
be protected from exposure to corrosive motor exhaust and ejection

TeleMetrum is a 1 inch by 2¾ 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
the e-matches for apogee and main ejection charges depart from the
fin can end of the board, meaning an ideal “simple” avionics
bay for TeleMetrum should have at least 10 inches of interior length.

TeleMini v1.0 is ½ inches by 1½ inches. It was
designed to fit inside an 18mm air-frame tube, but using it in
a tube that small in diameter may require some creativity in
screw terminals for the battery and power switch. The larger
board fits in a 24mm coupler. There's also a battery connector
for a LiPo battery if you want to use one of those.

EasyMini is built on a 0.8 inch by 1½ inch circuit board. It's
designed to fit in a 24mm coupler tube. The connectors and
screw terminals match TeleMini v2.0, so you can easily swap between
EasyMini and TeleMini.

TeleMega is a 1¼ inch by 3¼ inch circuit board. It was
designed to easily fit in a 38mm coupler. Like TeleMetrum,
TeleMega has an accelerometer and so it must be mounted so that
the board is aligned with the flight axis. It can be mounted
either antenna up or down.

Each flight computer logs data at 100 samples per second
during ascent and 10 samples per second during descent, except
for TeleMini v1.0, which records ascent at 10 samples per
second and descent at 1 sample per second. Data are logged to
an on-board flash memory part, which can be partitioned into
several equal-sized blocks, one for each flight.

The on-board flash is partitioned into separate flight logs,
each of a fixed maximum size. Increase the maximum size of
each log and you reduce the number of flights that can be
from the flight computer before it fills up. The flight
computer will still successfully control the flight even if it
cannot log data, so the only thing you will lose is the data.

the firmware operates in is determined at start up time. For

short beep while "dah" means a long beep (three times as
long). “Brap” means a long dissonant tone.

complete explanation of how GPS works is beyond the scope of
this manual, but the bottom line is that the GPS receiver
is turned back on, the GPS system should lock very quickly, typically
long before igniter installation and return to the flight line are
complete.

One of the unique features of the Altus Metrum system is the
ability to create a two way command link between TeleDongle
and an altimeter using the digital radio transceivers
lights on the devices. The red LED will flash each time a packet
is transmitted, while the green LED will light up on TeleDongle when
it is waiting to receive a packet from the altimeter.

An important aspect of preparing a rocket using electronic deployment

or main charges from a safe distance using your computer and

Our flight computers all incorporate an RF transceiver, but
it's not a full duplex system... each end can only be transmitting or
receiving at any given moment. So we had to decide how to manage the
packet takes a full second to transmit, we recommend an
interval of at least 5 seconds to avoid consuming too much
battery power or radio channel bandwidth.

Configuring an Altus Metrum altimeter for flight is very
simple. Even on our baro-only TeleMini and EasyMini boards, 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.

The AltosUI program provides a graphical user interface for
interacting with the Altus Metrum product family. AltosUI can
monitor telemetry data, configure devices and many other
buttons, one for each major activity in the system. This chapter
is split into sections, each of which documents one of the tasks
provided from the top-level toolbar.

receives. To download that to a computer for use with AltosUI,
simply remove the SD card from your Android device, or connect

We've designed a simple GPS based radio tracker called TeleGPS.
If all goes well, we hope to introduce this in the first
half of 2014.

Building high-power rockets that fly safely is hard enough. Mix
in some sophisticated electronics and a bunch of radio energy
and some creativity and/or compromise may be required. This chapter
contains some suggestions about how to install Altus Metrum
products into a rocket air-frame, including how to safely and
reliably mix a variety of electronics into the same air-frame.

The first consideration is to ensure that the altimeter is
securely fastened to the air-frame. For most of our products, we
prefer 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.

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 used in TeleMetrum and TeleMega is
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
70cm amateur band, so you should avoid lengths that are a
simple ratio of that length; essentially any multiple of ¼
of the wavelength (17.5cm).

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
the products of APCP or BP combustion, so make sure the ebay is
carefully sealed from any compartment which contains ejection
charges or motors.

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.

There are only two calibrations required for TeleMetrum and
TeleMega, and only one for TeleDongle, TeleMini and EasyMini.
All boards are shipped from the factory pre-calibrated, but
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
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.

While barometric sensors are factory-calibrated,
accelerometers are not, and so each must be calibrated once
installed in a flight computer. Explicitly calibrating the
