EARTH OBSERVATION
Sharp-Eyed Proba-V Works Around The Clock
by Staff Writers
Paris (ESA) Feb 20, 2014


Proba-V images the Black Sea, including the Winter Olympics host city of Sochi (centre of image). Cloud covers much of the Black Sea itself. This Proba-V Vegetation image was acquired on 7 February 2014 at 333 m resolution. Image courtesy ESA/VITO. For a larger version of this image please go here.

More than 5000 images, 65 daily global maps and six 10-day global syntheses, plus a quick peek at the Olympics: in its first two months of work, the vegetation-monitoring Proba-V minisatellite has yielded a valuable harvest for around a hundred scientific teams around the globe.

Measuring less than a cubic metre, Proba-V tracks vegetation growth across the world on a near-daily basis - 93% of the globe is covered in one day, 100% in two days - using its main wide-viewing Vegetation camera.

Launched last May, the satellite began its routine working life in early December.

Scientists can use the Proba-V output with confidence, knowing they have been cross-calibrated with its predecessor, the Vegetation sensor on France's Spot-5 satellite.

The new camera improves on Spot's in one important respect: while the first-generation instrument images the world at 1 km resolution, Proba-V's vision is much sharper.

It offers daily near-global coverage at 333 m resolution with a geolocation accuracy better than one pixel.

For the central 500 km of Proba-V's 2250 km field of view the resolution is even sharper - about 100 m in the visible and near-infrared and some 200 m in the shortwave infrared.

In fact, Proba-V's excellent performance means global products with 100 m resolution are probably possible in the near future. A future 100 m-resolution Proba mission is now being studied.

The output is processed for ESA by Belgium's Flemish institute for technological research, VITO. "VITO has developed a processing chain for 100 m visible and near infrared syntheses," explained Bart Deronde, its Proba-V operations manager.

"But before we go on to develop an operational product a thorough analysis needs to be made on the product quality - so we are asking interested research teams to contact VITO if they want to contribute to this effort, planned during the next six months."

Commercial Vietnamese cousin
Proba-V is set to gain a commercial 'cousin' - the minisatellite's Belgian builder, QinetiQ Space, has sold a comparable mission, including satellite and ground station, to Vietnam.

A Belgian consortium has signed a contract with the Vietnam Academy of Science and Technology for a mission called VNREDSat-1B: Vietnam Natural Resources, Environment and Disaster Monitoring satellite.

This hyperspectral Earth observation mission, comparable in design to the Proba-V platform and elements of its payload, will be used for agricultural monitoring, including crop cultivation tracking and water management.

With a 100 km field of view to gather high-resolution hyperspectral and panchromatic imagery from its 640 km-altitude orbit, VNREDSat-1B will revisit any single point on Earth every five days.

Its predecessor was launched on the same Vega rocket as Proba-V, on 7 May 2013.

The contract comprises a total package for building and supply of a complete satellite infrastructure to Vietnam: this includes the satellite, test facilities, ground station and its operation for one year.

Other members of the consortium include space software specialist Spacebel, optomechanical manufacturer Amos, the Centre Spatial de Liege research centre and VITO, working on the user segment design.

NASA Data Find Some Hope for Water in Aral Sea Basin
Washington DC (SPX) Feb 19, 2014
A new study using data from NASA satellite missions finds that, although the long-term water picture for the Aral Sea watershed in Central Asia remains bleak, short-term prospects are better than previously thought. Once the fourth largest inland sea in the world, the Aral Sea has lost 90 percent of its water volume over the last 50 years. Its watershed - the enormous closed basin around ... read more
