The specifications state that the unit has 'extended squitter' compatible
with ADS-B. What exactly does this mean?

It sounds like the unit can interface with a GPS signal source and include
that data with the Mode S data.

A correspondent wrote to me that "The rather rude term "squitter" refers
to the burst transmission that Mode S uses; the extended squitter has an
uplink as well as a downlink and has more capacity to transmit
additional data such as gps position that can then be used as the basis
of an anti-collision warning system."

I also heard that the FAA has picked two technologies (to work side by
side) for that datalink, and one of them is Mode S Extended Squitter,
which is already a capability of most Mode S airborne equipment (e.g.
the GTX330). "It's the same datalink over which the FAA provides its
Traffic Information System".

There's a Mode S FAQ here:

http://www.eurocontrol.int/mode_s/FAQ/mode_s_faq.htm

on which I found: "The Mode S transponder extended squitter is also an
enabler for ADS-B operation".

If anyone knows more, or finds this inaccurate and can correct it, I
should be grateful for that information.

By the way, the Volkslogger Mode S transponder which has been in
progress for some time is now announced as having EASA certification.
[See http://www.volkslogger.de/ .]

I imagine that it will therefore soon be on sale in Europe.

Incidentally, I am not an agent for nor sell their products, but I own a
VL logger and may buy their transponder in due course.

Fransois van Haaff, the technical officer for Airspace and Equipment of =

(e.g. the expected release dates and prices of LAST) may be outdated, as =
his article is from 2004/4.

By the way, I am still angered at this essentially compulsory =
requirement to buy new and expensive equipment. It may have become =
desirable and even essential in very busy areas, but for those of us who =
fly where traffic is not dense, airspace is simple and where see and =
avoid has never failed, it feels like extortion. More so when the ATC =
agencies themselves have delayed implementing mode-S enabled ground =
equipment.
