I do not see the need for a $9000 ADS-B out ?transponder replacement? for general
aviation by the year 2020.
Look at our chip for the Narco Avionics AT-155 transponder. There is a front panel
for controls, a microwave receiver to hear ?radar? interrogations, a microwave
transmitter to reply, a power supply, and our ?chip?, an Actel 42MX24 FPGA. In
the AT-155 you get a free AIS-P out. When the transponder is not busy
transponding, it sends out a single short (64 microsecond) Mode S packet that
states aircraft position and velocity. Works everywhere right now, ?radar? can
listen. The point is not what is out there, is no longer in production, for free.
The point is, ADS-B out is an AT-155 with the microwave receiver and front panel
controls and microprocessor removed, so why should ADS-B out cost $9000 when
the TailLight transponder only costs a few hundred dollars to manufacture. AS-B
out should cost half the price of the AT-155, because there is so much costly stuff
that doesn?t have to be there.
All you need for ADS-B out is the microwave transmitter, a power supply, and ?the
chip?, do not need all those front panel controls or the microprocessor or
microwave receiver.
In order to get the cost down from $9000 for ADS-B out, the TailLight Consortium
will make the following offer: The TailLight Consortium will offer, for a $100 license
fee, ?the chip? for each ADS-B out. It will be the AT-155 chip, with ATCRBS
transponder function removed. That gives you AIS-P out for free, which works
everywhere now, and ?radar? can listen ? don?t need new expensive ground
equipment. And we will offer it with ADS-B protocol in addition. We offer this with
the following improvement:
The TailLight AIS-P/ADS-B out will transmit the aircraft ID, which is a part of the
ADS-B protocol not a part of the AIS-P protocol (or else it wouldn?t be an ADS-B
out, just an AT-155 without a working transponder). Because identity
transmission, part of the ADS-B protocol, enables automatic computer generated
monthly billing for ?air time?, enables automatic computer generated ticket writing
for off-altitude or sticking a wingtip into restricted airspace, enables (and this is the
most important part) terrorist exposure to both the air traffic control system and to
air travel; we will generate a new unique aircraft identity randomly every time that
the aircraft is power up for flight. This improvement will cost nothing, and is a part
of the offer.
