== Introduction and Overview
|
|
|
|
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
|
|
releasing all of our hardware and software designs under open licenses,
|
|
we also hope to empower you to take as active a role in our collective
|
|
future as you wish!
|
|
|
|
Our goal is to include in this document all of the information required
|
|
to successfully configure and use Altus Metrum products. But
|
|
documentation is a lot like software in that it can contain "bugs",
|
|
and can probably always be improved! If you have questions that
|
|
aren't answered in this manual, or just need a little help figuring
|
|
things out, we strongly suggest joining the Altus Metrum user email
|
|
list, which you can do by visiting
|
|
https://lists.gag.com/mailman/listinfo/altusmetrum. There's a lot
|
|
of useful information in the mailing list archives!
|
|
|
|
The first device created for our community was TeleMetrum, a dual
|
|
deploy altimeter with fully integrated GPS and radio telemetry
|
|
as standard features, and a “companion interface” that will
|
|
support optional capabilities in the future. The later versions
|
|
of TeleMetrum, v2 and newer, have all of the same features but with
|
|
improved sensors and radio to offer increased performance.
|
|
|
|
Our second device was TeleMini, a dual deploy altimeter with
|
|
radio telemetry and radio direction finding. The first version
|
|
of this device was only 13mm by 38mm (½ inch by 1½ inches) and
|
|
could fit easily in an 18mm air-frame. The latest version, v3.0,
|
|
includes a beeper, higher power radio, extended on-board
|
|
flight logging and an improved barometric sensor.
|
|
|
|
TeleMega is our most sophisticated device, including six pyro
|
|
channels (four of which are fully programmable), integrated GPS,
|
|
integrated gyroscopes for staging/air-start inhibit and high
|
|
performance telemetry.
|
|
|
|
EasyMini is a dual-deploy altimeter with logging and built-in
|
|
USB data download.
|
|
|
|
EasyMega is essentially a TeleMega board with the GPS receiver
|
|
and telemetry transmitter removed. It offers the same 6 pyro
|
|
channels and integrated gyroscopes for staging/air-start inhibit.
|
|
|
|
TeleDongle v0.2 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. The latest version, TeleDongle
|
|
v3, has all new electronics with a higher performance radio
|
|
for improved range.
|
|
|
|
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 AltosDroid
|
|
application installed from the Google Play store.
|
|
|
|
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.
