55 <title>Quick Start Guide</title>
57 TeleGPS is designed to be easy to use. Requiring no external
58 components, flying takes just a few steps.
62 <title>Handling Precautions</title>
64 All Altus Metrum products are sophisticated electronic devices.
65 When handled gently and properly installed in an air-frame, they
66 will deliver impressive results. However, as with all electronic
67 devices, there are some precautions you must take.
70 The Lithium polymer batteries have an
71 extraordinary power density. This is great because we can fly with
72 much less battery mass... but if they are punctured
73 or their contacts are allowed to short, they can and will release their
75 Thus we recommend that you take some care when handling TeleGPS
76 to keep conductive material from coming in contact with the exposed metal elements.
79 As with all other rocketry electronics, Altus Metrum devices must
80 be protected from exposure to corrosive motor exhaust and ejection

87 <title>GPS Receiver</title>
89 TeleGPS uses the u-Blox Max-7Q GPS receiver.
93 <title>Micro-controller</title>
95 TeleGPS uses an NXP LPC11U14 micro-controller. This tiny
96 CPU contains 32kB of flash for the application and 4kB of RAM for
97 temporary data storage.
101 <title>Lithium Polymer Battery</title>
103 Shipping restrictions may prevent us from including a battery
104 battery with TeleGPS.
108 <title>Mechanical Considerations</title>
110 TeleGPS is designed to be rugged enough for typical rocketry
115 <title>On-board data storage</title>
117 TeleGPS has some bytes of non-volatile storage, separate
118 from the code storage memory. The TeleGPS firmware uses this
