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

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.
