- Moving Weather for Automatic Message Switching System


Moving Weather is an automatic message switching system fully conforming to all applicable WMO and ICAO regulations. It is designed to operate according to the store-and-forward principle, but you are free to provide your own value by compilation of new information out of the received data. You will be surprised how well Moving Weather fits your expectations.

Message and file switching system that will lead you on the information highway.

WMO Plan for Migration to TDCF:
“Migration of the category 1 meteorological observation data (SYNOP, TEMP, PILOT, CLIMAT) should be completed in November 2010”

Is your switching system ready for this change?

Choose one that is prepared!

Moving Weather is an automatic message switching system fully conforming to all applicable WMO and ICAO regulations. It is designed to operate according to the store-and-forward principle, but you are free to provide your own value by compilation of new information out of the received data. You will be surprised how well Moving Weather fits your expectations.

Exploit the full power of Moving Weather and enjoy the reliability and versatility of this state-of-the-art system fully customized to what you really need. Do not waste your time looking for a needle in a haystack. We are at the beginning of the new millennium and the world of information & communication technologies has never been more fascinating. But, at the same time, it has never been more complicated. Fortunately, the solution is at your fingertips. Just reach out your hand…

Basic Information

Table-driven Code Forms

There is no need to despair. Thoughts the WMO-requested migration plan to BUFR/CREX is knocking at your door (November 2005), with Moving Weather you are always on the safe side. And you can still use the old formats, for how long your desire.

Non-WMO Data Switching

Ever wonder what to do with oh-so-many data in non-WMO formats? NWP outputs, MPEG videos, JPEG images, and the like…? Now just wait until you hear what Moving Weather is capable of: FTP, SFTP, SCP, RCP, RSYNC, SMB… file distribution has never been easier. Just think of message switching — only now with files too!

ICAO Amendment 73

There have been recently some changes in formats of the METAR/SPECI and TAF messages. With Moving Weather, you will never stay behind: receive these new formats on input AND provide them in your own compiled bulletins… just a couple of clicks needed. What? Oh, yes, you can still use the old formats…

Powerful & Reliable

With Moving Weather, the words powerful and reliable take on a new meaning. You have never before seen a switching system that is more “rock-stable”. Fault-tolerancy is our second name… high availability is second-to-none. Just sit back and enjoy the power of up to 500 messages switched per second.

Lines and More

Still using legacy TELEX machines? Or perhaps X.25 is your good ol’ network? “Aha!” you say, “but I want e-mail, RMDCN, FTP, ISDN… how about that?” Well, in Moving Weather you have no problem. Just name the technology and you will get it.

Modern User Interface

We are sure you have already met a program that kept getting in your way and tried to control YOU. Do not fear — you would have to look hard (and in vain) to find a more user-friendly system than Moving Weather. Its modern, intuitive and highly ergonomic user interface is just imploring to be unleashed.

Store & Forward

The principial mode of operation of Moving Weather adheres to the store & forward principle: data reception, storage and data transmission. However, an added value is asserted by the possibility to compile new information out of existing data. All operations are in strict conformance with applicable WMO and ICAO regulations.

Circuits and Lines

There are many types of data circuits and communication lines supported in Moving Weather: TCP, FTP, RMDCN, e-mail, phone, fax, X.25, TELEX, async lines, AFTN/CIDIN, MDD, SADIS, RETIM… Up to 64000 different lines organized into arbitrary groups are possible.

Data Formats

Moving Weather system operates on all kinds of meteorological data, including WMO messages of the textual (SYNOP, METAR, TAF, CLIMAT…) and binary (BUFR, GRIB) types, as well as arbitrary (non-WMO) files such as NWP outputs, video sequences, static images etc.

Modern User Interface

A tremendous effort is spent to make Moving Weather the most user-friendly system on the market, making the daily work of operators and other users as comfortable and ergonomic as possible. It is easy to get absorbed by the simplicity of the routine tasks carried out using standard mouse-and-keyboard operations.

Extensible & Open

New principles, technologies and rules emerge almost every day. Moving Weather system keeps the pace thanks to its open and easily extensible architecture designed and developed using modern object-oriented technologies (C++, multi-threading, …).

Standalone PC

Are you tight on budget but still in need of switching system? Moving Weather is prepared to run on as little as a standalone PC, even in an unattended mode. Once you decide that you need something more, you can upgrade to a more powerful server or a server cluster. Do not worry about your data: scalability means they will go with you.

HA Cluster

Your data is one of the most valuable assets of your meteorological infrastructure. Moving Weather offers to you two ways to assert their integrity: fault-tolerancy and high-availability. You can safely rely on the fault-tolerant hardware with duplicated hot-plug components. And for yet more safety, a tandem of two HA servers will never let you down.

Integration and Scalability

There is no such thing today as an isolated system. Moving Weather is not an exception and it has to be integrated into your communication and processing infrastructure. Well, more than that: this is the heart and soul of your meteorological network.
