# TeleLaunch — Multi-channel Wireless Launch Controller System #
TeleLaunch is secure radio-controlled rocket launch system capable of
operating up to 792 pads from a single controler. A typical TeleLaunch
system consists of one LCO unit and one or more pyro units.
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 low power using
Altus Metrum's proven modulation and coding schem to avoid interference
with any rocketry electronics or other communication devices.
All boards in the TeleLaunch system are easily configured using USB for
parameters like operating frequency, callsign, cryptographic key, and
in the case of pyro units the designated bank number.
## Launch Control Products ##
All launch control units in the TeleLaunch system are designed to use
a lithium polymer battery that can be recharged over USB. They support
distinct arm and fire switches, continuous indication of igniter
continuity, and have super-bright LED indicators for remote arming,
continuity, and RF link quality plus an audible indication of arming.
### TeleLCO ###
TeleLCO controls up to 99 TeleFire banks, comes packaged in a rugged
case, and is typically placed on a table for use by the designated LCO.
* Large 1.36 inch LCD display for selected bank and pad
* Rotary knob for pad selection
* Packaged in [Pelican 1170 orange box](https://www.pelican.com/us/en/product/cases/protector/1170)
Drag races are supported with a separate normal/drag mode selection switch,
drag mode LED, and select pushbutton. Channels that are included in the
current drag race selection have blinking continuity indicators.
The TeleLCO hardware design is available from
[git.gag.com](http://git.gag.com) in the project
[hw/telelco](http://git.gag.com/?p=hw/telelco;a=summary).
### TeleLCOTwo ###
A small LCO unit capable of handling up to two pyro channels. TeleLCOTwo
is ideal for individuals, or clubs that have an existing launch control
system but want to use TeleLaunch for an "away" launch cell.
TeleLCOTwo is configured in advance by USB to know which two pyro channels
it should interact with, and then a simple rocker switch selects between
the two during use.
TeleLCOTwo comes packaged in a weather-sealed polycarbonate box with
switches on one face, and BNC antenna connector and USB connectors
through the box walls. It can be placed on a table, but is typically
hand-held during operation.
The TeleLCOTwo hardware design is available from

[hw/telelcotwo](http://git.gag.com/?p=hw/telelcotwo;a=summary).
## Pyro Boards ##
Each pyro board in the TeleLaunch system uses FET technology for lowest
possible resistance paths, allowing maximum current to be reliably
delivered from the power source to the igniter leads. TeleFire boards can
be powered by any 10-15V supply. This would typically be a 12V lead acid
battery, but 3-cell lithium polymer packs used in RC aircraft are also
suitable.
Each board features:
* Continuity Detection. Igniter continuity uses a low-current sensing
system which sends only 100µA through the igniter to prevent false
ignition.
* Super-bright LEDs for 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. When in the safe position, power is completely
disconnected from the igniter circuits to prevent any possibility
of the LCO accidentally engaging firing circuits during rocket
preparations at the pad.
* Each board is designed to fit in a standard Hammond weather-sealed
polycarbonate enclosure with weather-sealed rocker switches for
power and arming plus cable glands for DC input cable and igniter
output cables. Alternatively, boards can be configured to mount
in the user's choice of enclosure, such as a metal ammo box or
larger NEMA enclosure with space for the user's choice of
external connectors.
### TeleFireTwo ###
TeleFireTwo is a pyro board supporting two igniter circuits. This
makes TeleFireTwo ideal for individuals, launch trailers, or for "away
cells" at larger club launches.
All high-current connections are made on the board using standard
1/4-inch spade lugs, with screw terminals for the siren and strobe. This
allows for easy packaging and quick board swaps.
The photo above is of an early single-channel prototype, the design has
changed significantly since then and we'll take new photos someday. The two
switches are for power on/off and safe/arm. The two cables are for DC power
in and igniter leads out.
The TeleFireOne hardware design is available from
[git.gag.com](http://git.gag.com) in the project
[hw/telefiretwo](http://git.gag.com/?p=hw/telefiretwo;a=summary).
### TeleFireEight ###
TeleFireEight has eight igniter circuits, making it ideal for use at
club launches. Larger clubs or launch site setups can use multiple
boards to organize the site into multiple banks with up to 8 rockets
each.
For ease of use and quick reconfiguration, a simple DIP switch on the board
inside the ammo box is used to select any of the first 8 banks, which is more
than sufficient for most club needs. If all switches are off, the bank
number up to 99 configured over USB will be used instead.
The above photo shows a fully packaged early production version, with integral
12 Ah sealed lead acid battery. There are another four pyro outlets on the
other side of the box, making the design ideal for placing in the middle of
an 8-rail bank.
The TeleFireEight hardware design is available from
[git.gag.com](http://git.gag.com) in the project
[hw/telefireeight](http://git.gag.com/?p=hw/telefireeight;a=summary).
## Documentation ##
There's a cheat-sheat inside the lid of TeleLCO that has proven to be
completely sufficient for our prototype users to figure out and use the
system.
A complete manual for the TeleLaunch system is available in
[html](../AltOS/doc/telelaunch.html) and [pdf](../AltOS/doc/telelaunch.pdf)
formats.
## Software ##
TeleLaunch firmware is part of the larger [AltOS](/AltOS) suite of
software. For now, configuration of frequencies, callsigns, and crypto
keys requires a laptop with terminal emulator and a USB cable, but we are
likely to produce an easier to use configuration program eventually.
## Availability ##
TeleLCO and TeleFireEight are now in production, and available for purchase
directly through the [Garbee and Garbee](https://shop.gag.com) online store.
Prototypes of the other products in this family have been built, deployed,
and used successfully. Updates to the designs are underway and we hope to
have additional products available in 2019.
