1.   Anticyclone Systems Ltd
Anticyclone Systems Ltd, founded in 1998, is a established design
house combining a unique blend of skills to bring innovative,
tightly coupled hardware and software solutions to the marketplace.
We are proud of our proven ability to deliver highly competitive
products world-wide and have built a reputation for delivering our
products within tight time scales.
We are also proud of the direct relationship we have with our
customers, and despite other organisations claiming they do this, we
are one of the few who really do centre our designs on real customer
feedback based on active products in the marketplace.
The unique combination of hardware and software expertise
available to us is our key to success. Anticyclone Systems Ltd is
currently focused on the RS232 data logging market and our AntiLog product range are good
examples of tightly coupled designs which give world class
We have historically provided software only solutions and
microcontroller based solutions to meet individual customer needs.
Examples include our WxWatch real time weather satellite image
reception system for the Royal Navy in the UK, a completely digital
radiosonde meteorological measurement system and a unique antenna
ground station control system for Azimuth/Elevation and X-Y tracking

2.   RS232 data logging
There are a vast range of electronic devices in the world that
can output data in RS232 format. Examples include Global
Positioning System (GPS) receivers, test and measurement equipment,
process control systems and communication systems. There is also a
sizeable requirement to log this data reliably. For example, to
performing system analysis, field trials data recording, or
equipment verification and validation.
With the advent of the personal computer (PC), RS232 data logging
was simplified because most PCs came as standard with an RS232
serial port, could run application software to log data from this
port and had sufficient disk storage to record the results. Since
then, laptops, palm tops and PDAS have been developed which can now
offer a portable data logging capability.
However, although the technology has improved, RS232 data logging
has not improved with it. Laptops, PDAs and the like were not
designed to be dedicated data logging devices and the operating
systems around them are generatlly not real time, so compromises in
terms of speed, reliability and ease of use have had to be made to
allow these devices to be as general purpose as possible. To log
RS232 data effectively requires a reliable, dedicated data logging
Our AntiLog product was
designed from the ground up to be this dedicated, reliable data
logging solution. We have combined a powerful stand alone
microcontroller solution with some tightly coupled software to
realise a highly portable RS232 data logging system which can write
to extremely small, lightweight, solid state FLASH media.
AntiLog is now in use
throughout the world in a very diverse range of applications
including transport development, civil and military GPS receiver
data logging, medical equipment monitoring, wildlife monitoring,
Unmanned Aircraft flight data recording, sea trials, crop yield
control, crane safety and a whole host of process control
So next time you need to log RS232 data, why not look at our AntiLog product range and see for
yourself the benefits of a dedicated data recording device.
3.   Receiving weather satellite images
There is no doubt that meteorological imagery from weather
satellite systems has greatly enhanced our ability to predict
weather conditions around the world. Visual and infra-red imagery
from weather satellites can see everything from small localised
changes in temperature to large tropical storms.
Processed weather satellite images are commonly used
by television stations to give viewers a more visual impression of
weather conditions. The weather is important to those who travel
and those who supply services that can be affected by the
There are two main types of satellite which can provide
unencrypted services to users almost anywhere in the world. The
first are polar orbiting satellites whose low earth orbits are
designed to give sun synchronous coverage of the earth. The orbits
extend up toward the polar regions of the earth. Geostationary
satellites are placed in orbits which maintain their relative
position to the earth's surface and can provide continuous coverage
over the same earth region from high altitude.
What is not commonly known is that live images from these weather
satellites can easily be decoded by anyone using low cost equipment.
There are several commercial and public domain programs and hardware
solutions available and very satisfactory images can be obtained.
However, not all systems are the same. What most systems lack is
very easy to use features with truly powerful automated facilities
for image reception requiring no user interaction (despite the
claims on their packaging!). It is also important to be able to
process images without any noticeable speed reduction whilst
decoding live images.
The first major product developed by
Anticyclone Systems Ltd was a professional weather satellite
reception solution that was packed with advanced features for the
time (WxWatch). The system was
supplied into the Royal Navy in the United Kingdom and had image
projection onto mapped surfaces, GPS position and time augmentation,
full overlay gridding with high resolution map overlays, automated
image reception, automated image administration. The system also
contained a full suite of image processing options including
contrast stretches, false colour, image combinations, unique
weighted digital filtering system and comprehensive meteorological
symbol editing including placement and editing of meteorological
symbols, text and weather fronts.
Although the software is an important part of the system, it is
also important to use the right hardware. A dedicated weather
satellite receiver must be used for good signal reception. Several
sources of radio signal exist close to the polar orbiting weather
satellite band (e.g. telephone paging systems in the United
Kingdom) which can cause reception interference to weather satellite
signals. It is also important to decode these incoming signals
correctly. Most systems use an 'interface card' which consists of
an analogue to digital converter in some kind of phased locked loop.
Some cards don't even do this, they just sample the incoming signal
asynchronously to keep the costs down. After extensive development,
Anticyclone Systems Ltd was able to offer a unique advanced
microprocessor controlled synchronous decoder (which also performed
simple asynchronous reception for Facsimile transmissions). The
decoder unit was also responsible for direct control of the weather
satellite radio receiver.
