European Meteorological Agency EUMETSAT Employs Time-Series Data Analysis to Monitor Satellites

Visual Numerics® TS-WAVE™ Automates Satellite Telemetry Data Plotting to Ensure Satellites Function Properly

HOUSTON, TX -- (MARKET WIRE) -- May 23, 2006 -- Visual Numerics, Inc., celebrating 35 years of producing leading numerical analysis and visualization software, today announced that EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites, is using Visual Numerics TS-WAVE™ to automate their telemetry data plot graphing for two Meteosat Second Generation (MSG) satellites. With TS-WAVE, an application for custom time series data analysis, EUMETSAT operations engineers are able to easily interpret data results and monitor the satellites to ensure both are functioning properly and able to disperse vital information such as weather changes.

The Meteosat Second Generation satellite series consists of four identically built satellites. Meteosat satellites disseminate updated information and imagery for weather forecasting as well as information on hydrology, agriculture and environmental/climate studies. The data collected is routinely used for studying weather and climate change, particularly severe weather changes, which has helped reduce losses of human life and property.

With the implementation of TS-WAVE, EUMETSAT can automatically produce 100 plots with approximately 250 parameters on a weekly basis in only 30 seconds without any user interaction. The European weather satellite organization can also produce long-term forecasts with a year's worth of data, a task that had been impossible to perform previously.

"TS-WAVE saved us countless hours in manually creating plots," said Jenni Doonan, Spacecraft Operations Engineer at EUMETSAT. "Now we can automate runs overnight so that graphical satellite behavior reports are ready for our operations engineers' review the following morning. As a result, we're able to protect Europe's investment in satellites 24/7 and ensure they are always functioning optimally. We can also anticipate changes in performance and make adjustments to the satellites before any transmission problems occur."

In addition to automating processes, TS-WAVE's scripting ability made it easier for EUMETSAT to save templates and perform standardized checks on their data. Furthermore, TS-WAVE interfaces well with EUMETSAT's legacy tool PARDET. PARDET was previously developed to use in conjunction with Microsoft Excel to produce a text file output that could be imported and plotted. However limitations in Excel, with respect to the amount of data that could be plotted, prevented long-term data analysis. The ability to write new data handlers in TS-WAVE was used to make PARDET interface to TS-WAVE. This resulted in minimal changes to TS-WAVE but enormous improvement in the ability to analyze data.

"Satellite tracking can be difficult because it requires agencies to collect multiple channels of data at fixed or irregular times. Then agencies must transform, analyze and chart that data either in an exploratory post-processing mode or a real-time data collection mode. Most agencies find it difficult to synthesize the data quickly enough to produce instantaneous answers," said Phil Fraher, president and CEO of Visual Numerics. "We're thrilled that EUMETSAT relies on TS-WAVE for automatically plotting, visualizing, analyzing, and batch processing this sensitive time-based data, and proud that we can support their 14 year long project with a complete and cost-effective solution."


TS-WAVE is the time series analysis component of the PV-WAVE® Family of products. It is a highly extensible application that allows plot creation and batch processing of data. For those working with time-based data, it is the most reliable application base available for custom time-series data analysis. TS-WAVE is easy to use and customize for proprietary data formats, and is often used for telemetry data gathered from flight tests, range tests or satellite instruments. No other product offers TS-WAVE's data import features for proprietary and large file formats.


The European Organisation for the Exploitation of Meteorological Satellites is an intergovernmental organisation that establishes and maintains operational meteorological satellites for 19 European States (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland, Turkey and the United Kingdom). EUMETSAT has signed 11 Cooperating State Agreements. Those with Bulgaria, Croatia, Hungary, Latvia, Lithuania, Poland, Romania, Slovenia and the Czech Republic have entered into force whereas the Agreements with Serbia and Montenegro and Iceland are to be ratified in the near future.

EUMETSAT is currently operating Meteosat-6, -7 and -8 over Europe and Africa, and Meteosat-5 over the Indian Ocean.

The data, product and services from EUMETSAT's satellites make a significant contribution to weather forecasting and to the monitoring of the global climate.
