Altus Metrum flight computers need an external power switch
to turn them on. This disconnects both the computer and the
pyro charges from the battery, preventing the charges from
firing when in the Off position. The switch is in-line with
the positive battery terminal.

As mentioned above in the section on hooking up pyro
charges, one lead for each of the pyro charges is connected
through the power switch directly to the positive battery
circuit between the negative pyro terminal and the ground
terminal, firing the igniter. Specific instructions on how
to hook this up will be found in each section below.

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.

TeleMega provides explicit support for an external pyro
battery. All that is required is to remove the jumper
between the lipo terminal (Bottom 3) and the pyro terminal
(Bottom 1) and the positive pyro battery to the pyro battery
input (Bottom 2). You can then use the existing pyro screw
terminals to hook up all of the pyro charges.

Because TeleMega has built-in support for a separate pyro
battery, if you want to fly with just one battery running
both the computer and firing the charges, you need to
circuit. TeleMega has two screw terminals for this—hook a
wire from the Lipo terminal (Bottom 3) to the Pyro terminal
(Bottom 2).

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.

fundamental modes, “idle” and “flight”. Which of these modes
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.

TeleMetrum and TeleMega include 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 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.

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
40mW devices. We hope to fly boards to higher altitudes over
time, and would of course appreciate customer feedback on
performance in higher altitude flights!

TeleMetrum v2.0 and TeleMega can send APRS if desired, and the
interval between APRS packets can be configured. As each APRS
packet takes a full second to transmit, we recommend an
arbitrary text in it. AltOS uses this to send status
information about the flight computer. It sends four fields as
shown in the following table.

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
using AltosUI over USB or or radio link via TeleDongle. Read
the Configure Altimeter section in the AltosUI chapter below
for more information.

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

altimeter and TeleDongle must be configured to the same
frequency to successfully communicate with each other.

This sets the callsign used for telemetry, APRS and the
packet link. For telemetry and APRS, this is used to
identify the device. For the packet link, the callsign must
match that configured in AltosUI or the link will not
work. This is to prevent accidental configuration of another
Altus Metrum flight computer operating on the same frequency nearby.

This selects how often APRS packets are transmitted. Set
this to zero to disable APRS without also disabling the
regular telemetry and RDF transmissions. As APRS takes a
full second to transmit a single position report, we
recommend sending packets no more than once every 5 seconds.

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.

Selecting this item brings up a dialog box listing all of the
connected TeleDongle devices. When you choose one of these,
AltosUI will create a window to display telemetry data as
data relevant to the current state of the flight. You can select
other tabs at any time. The final 'table' tab displays all of
the raw telemetry values in one place in a spreadsheet-like format.

The 'Launch Pad' tab shows information used to decide when the
rocket is ready for flight. The first elements include red/green
indicators, if any of these is red, you'll want to evaluate
The Launchpad tab also shows the computed launch pad position
and altitude, averaging many reported positions to improve the
accuracy of the fix.

This tab is shown during Boost, Fast and Coast
phases. The information displayed here helps monitor the
rocket as it heads towards apogee.
Finally, the current igniter voltages are reported as in the
Launch Pad tab. This can help diagnose deployment failures
caused by wiring which comes loose under high acceleration.

Once the rocket has reached apogee and (we hope) activated the
apogee charge, attention switches to tracking the rocket on
the way back to the ground, and for dual-deploy flights,
e-matches are designed to retain continuity even after being
fired, and will continue to show as green or return from red to
green after firing.

adapter instead of feedline between the antenna feedpoint and

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.

479648"></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 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.

490000"></a>4. Radio Frequency Interference</h2></div></div></div><p>
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
