GMES Masters 2012

Chelys is taking part in the GMES Masters European Earth Monitoring Competition 2012 for the second year in a row. Last year, Chelys’ Satellite Rapid Response System (SRRS), which participated in the category “Emergency Management Services”, was the competition’s overall winner of the “Best Service Challenge”. Thank you to all of you who voted for us!

SRRS Participating in GMES Masters Competition – Thank you to all who voted!

GMES Master Competition - Best Service Challenge

In emergency situations it is necessary to provide a response as quickly as possible. When the type of emergency depends on the use of satellite data, it then becomes necessary to plan their acquisition, processing and distribution, having teams ready 24 hours per day, 7 days a week, to respond to this type of situation.

The Satellite Rapid Response System was created by CHELYS precisely with the intent of making satellite data available as quickly as possible, as images and value-added products.

The constellation of satellites known as GMES (Global Monitoring for Environment and Security) that will be launched starting in 2013, thanks to low revisiting times and the planning of the whole mission already present on board the satellite, will allow monitoring of our planet as never seen before.

SRRS is participating in the GMES Masters Competition in the Best Service Challenge. You can visit SRRS at the following link:
gmes.chelys.eu

If you consider this type of service useful, if you like it, if you would like to continue using it with new data that will be made available by GMES, then vote for the service at the following link:

It is also important to note that although SRRS is participating in the Emergency Response category, it actually has a much wider range of applications, such as Ocean, Land or Climate Change.

If you have any thoughts regarding the service or ideas on ways to improve it, please leave us a comment.

Envisat Extension Orbit – Update

41.8N 12.4E

October 28th, 2010 Category: Earth Observation, Events

ESA Envisat-1

The Envisat mission was launched in March 2002 for 5-year nominal lifetime. Consequently the on-board hydrazine capacity was designed for a 5-year duration operation. Careful management of the satellite orbital manoeuvres allowed saving enough hydrazine for operating nominally Envisat for an additional 3.5 years, i.e. until end 2010.

The operations of the Envisat satellite beyond end 2010 require modifying the orbital characteristics of the mission. Careful trading between all possible options led to the selection a new orbit, called the “Envisat Extension Orbit“, which allows:
1) operating the mission for an additional 3 years, with a minimum amount of hydrazine,
2) ensuring the continuity of the maximum number of Envisat applications, with the exception of ASAR interferometry which will be degraded.

The Envisat extension orbit will be implemented through an altitude decrease of 17.4 km which will be reached through different orbital manoeuvres starting on 22 October 2010.

Consequently, the Envisat data flow will be suspended during the period 22 October to 01 November 2010. The data flow will resume on 02 November 2010.

The Envisat mission represents an important goal in the field of Earth Observation. Chelys will follow the entire operation attentively, as we are also the real time image generation software (Miravi) provider for the Meris sensor. This post will be updated in the next few days in order to provide a preview of the Envisat images at the end of the maneuver as soon as its sensors are reactivated.

Update

The last OCM (Orbit Control Manoeuvre) finished in time without problems on October 26th. The satellite instruments are gradually resuming their nominal condition and the dissemination to the users is started. However the ESA disclaimer is clear: users are invited to discard such data until November 2nd, 2010 as they are destined only for the ESA internal verification.

We started generating the first images using the “new” data, and the results, despite some geolocation problems, are very promising. Here below are some images generated after the completion of the manoeuvre.

POLinSAR 2009, The 4th International SAR Workshop

December 3rd, 2008 Category: Earth Observation, Events

The 4th International Workshop on Science and Applications of SAR Polarimetry and Polarimetric Interferometry - POLinSAR 2009

The European Space Agency is organising POLinSAR 2009, the 4th International Workshop on Science and Applications of SAR Polarimetry and Polarimetric Interferometry, which will be hosted in ESRIN, Frascati, Italy on 26-30 January 2009.


Objectives

The main objectives of the workshop are to:

  • Provide a forum for scientific exchange and to initiate and encourage close collaboration between individual research groups
  • Exploitation of spaceborne missions
  • Present new results from the latest studies in the field and to assess the state-of-the-art
  • Present polarimetric and interferometric results from ALOS PALSAR, RADARSAT-2 and TerraSAR-X
  • Assess the available Pol-InSAR tools and datasets
  • Review the bio-geophysical parameters that can be retrieved and their accuracy
  • Make recommendations for algorithm development and new products, future missions and applications
  • Report on progress/status of recommendations of PolInSAR 2007

The workshop will focus on theory and methods in the fields of SAR Polarimetry and Polarimetric Interferometry around the following theme:

  1. SAR Polarimetric Interferometry (Pol-InSAR)
  2. Theoretical Modelling
  3. Applications of SAR Polarimetry
    • Land: Forest, Agriculture, Environment (Urban, global change, land cover), Wetlands
    • Ocean: Pollution Monitoring, Ship detection, Ocean Parameters Retrieval, Sea Features
    • Cryosphere: Snow, Land Ice and Sea Ice Monitoring
    • Hazards: Fire Monitoring, Volcanoes, Flooding, Earthquake
  4. Polarimetry and Persistent Scatterer Interferometry (PSI)
  5. Compact Polarimetry
  6. ALOS PALSAR, TerraSAR-X, RADARSAT-2, COSMO-SkyMed results
  7. Future Spaceborne missions for Pol-InSAR
  8. Airborne Pol-InSAR campaigns

The island of Rhodes

September 9th, 2008 Category: Events, Snapshots

September 9th, 2008 - The island of RhodesGreece

September 9th, 2008 - The island of Rhodes

The island of Rhodes is shaped like a spearhead, 79.7 km (49.5 mi) long and 38 km (24 mi) wide, with a total area of approximately 1,400 square kilometres (541 sq mi) and a coastline of approximately 220 km (137 mi). The city of Rhodes is located at the northern tip of the island, as well as the site of the ancient and modern commercial harbours. The main air gateway (Diagoras International Airport, IATA code: RHO) is located 14 km (9 mi) to the southwest of the city in Paradisi. The road network radiates from the city along the east and west coasts.

In terms of flora and fauna, Rhodes is closer to Asia Minor than to the rest of Greece. The interior of the island is mountainous, sparsely inhabited and covered with forests of pine (Pinus brutia) and cypress (Cupressus sempervirens). The island is home to the Rhodian deer. In Petaludes Valley (Greek for “Valley of the Butterflies”), large numbers of tiger moths gather during the summer months. Mount Attavyros, at 1,216 metres (3,990 ft), is the island’s highest point of elevation. While the shores are rocky, the island has arable strips of land where citrus fruit, wine grapes, vegetables, olives and other crops are grown.

Outside of the city of Rhodes, the island is dotted with small villages and beach resorts, among them Faliraki, Lindos, Kremasti, Haraki, Pefkos, Archangelos, Afantou, Koskinou, Embona (Attavyros), Paradisi, and Trianta (Ialysos). Tourism is the island’s primary source of income.
