# TeleLaunch — Multi-channel Wireless Launch Controller System #
TeleLaunch is secure radio-controlled rocket launch system capable of
operating up to 400 pads from a single controler. A typical TeleLaunch
system consists of one LCO board and one or more pyro boards. The LCO
boards available include the full-featured TeleLCO, and the much simpler
TeleLCOTwo. Avaialbe pyro boards include TeleFireOne and TeleFireFour,
which control one or four pads, respectively.
## TeleLCO ##
TeleLCO controls up to 100 TeleFire boxes and is powered by a
rechargable lithium polymer
* USB connection to charge battery.
* Large 1.36 inch LCD display for selected pad
* Rotary knobs for pad selection
* LED indicators for remote arming, continuity and RF quality
* Arming switch and firing button
Circuit diagrams and PCB layouts are provided here:

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

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