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. A typical TeleLaunch
7 system consists of one LCO board and one or more pyro boards. The LCO
8 boards available include the full-featured TeleLCO, and the much simpler
9 TeleLCOTwo. Avaialbe pyro boards include TeleFireOne and TeleFireFour,
10 which control one or four pads, respectively.
14 TeleLCO controls up to 100 TeleFire boxes and is powered by a
15 rechargable lithium polymer
17 * USB connection to charge battery.
19 * Large 1.36 inch LCD display for selected pad
21 * Rotary knobs for pad selection
23 * LED indicators for remote arming, continuity and RF quality
25 * Arming switch and firing button

41 TeleFireFour has four igniter circuits, each of which uses a 70A
42 automotive relay to provide a low resistance path, high-current from
43 the power source to the igniter leads. TeleFireFour can be powered by any
44 10-15V supply, from 3-cell lithium polymer packs used in RC aircraft
45 to a 12V lead acid battery.
47 * Continuity Detection. Igniter continuity uses a low-current sensing
48 system which sends only 100µA through the igniter to prevent false
49 ignition. The circuit also detects a shorted relay.
51 * Local LED continuity, arming and RF quality indicators.
53 * Strobe and Siren. TeleFireFour has two 12V medium current (5A) outputs
54 to drive a siren and strobe light when the launch system is armed
57 * Local arming switch. A positive power switch shutting off the
58 igniters and relays prevents the LCO from engaging the firing

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