<title>Quick Start Guide</title>
<para>
TeleGPS is designed to be easy to use. Requiring no external
components, flying takes just a few steps.
</para>

<chapter>
<title>Handling Precautions</title>
<para>
All Altus Metrum products are sophisticated electronic devices.
When handled gently and properly installed in an air-frame, they
will deliver impressive results. However, as with all electronic
devices, there are some precautions you must take.
</para>
<para>
The Lithium polymer batteries have an
extraordinary power density. This is great because we can fly with
much less battery mass... but if they are punctured
or their contacts are allowed to short, they can and will release their
energy very rapidly!
Thus we recommend that you take some care when handling TeleGPS
to keep conductive material from coming in contact with the exposed metal elements.
</para>
<para>
As with all other rocketry electronics, Altus Metrum devices must
be protected from exposure to corrosive motor exhaust and ejection
charge gasses.

<title>Technical Information</title>
<section>
<title>GPS Receiver</title>
<para>
TeleGPS uses the u-Blox Max-7Q GPS receiver.
</para>
</section>
<section>
<title>Micro-controller</title>
<para>
TeleGPS uses an NXP LPC11U14 micro-controller. This tiny
CPU contains 32kB of flash for the application and 4kB of RAM for
temporary data storage.
</para>
</section>
<section>
<title>Lithium Polymer Battery</title>
<para>
Shipping restrictions may prevent us from including a battery
battery with TeleGPS.
</para>
</section>
<section>
<title>Mechanical Considerations</title>
<para>
TeleGPS is designed to be rugged enough for typical rocketry
applications.
</para>
</section>
<section>
<title>On-board data storage</title>
<para>
TeleGPS has some bytes of non-volatile storage, separate
from the code storage memory. The TeleGPS firmware uses this
to store information about the last completed
flight.
