3 # TeleLaunch — Multi-channel Wireless Launch Controller System #
5 TeleLaunch is secure radio-controlled rocket launch system capable of
6 operating up to 400 pads from a single controler. TeleLaunch consists
7 of two pieces, TeleLCO and TeleFire.
11 TeleLCO controls up to 100 TeleFire boxes and is powered by a
12 rechargable lithium polymer
14 * USB connection to charge battery.
16 * Large 1.36 inch LCD display for selected pad
18 * Rotary knobs for pad selection
20 * LED indicators for remote arming, continuity and RF quality
22 * Arming switch and firing button

30 TeleFire has four igniter circuits, each of which uses a 70A
31 automotive relay to provide a low resistance path, high-current from
32 the power source to the igniter leads. TeleFire can be powered by any
33 10-15V supply, from 3-cell lithium polymer packs used in RC aircraft
34 to a 12V lead acid battery.
36 * Continuity Detection. Igniter continuity uses a low-current sensing
37 system which sends only 100µA through the igniter to prevent false
38 ignition. The circuit also detects a shorted relay.
40 * Local LED continuity, arming and RF quality indicators.
42 * Strobe and Siren. TeleFire has two 12V medium current (5A) outputs
43 to drive a siren and strobe light when the launch system is armed
46 * Local arming switch. A positive power switch shutting off the
47 igniters and relays prevents the LCO from engaging the firing

54 ## Radio Communications ##
56 TeleLaunch uses a two-way digital radio communications system for
57 positive indication of all operations. The communications link is
58 secured with AES CBC-MAC to prevent accidental or intentional
59 operation from unauthorized transmitters.
61 TeleLaunch operates in the 70cm amateur band at 10mW to avoid
62 interference with any rocketry electronics.
