eOsphere Ground Stations   

The VxEos Ground System is eOsphere’s MODIS ground system designed for users who want to receive and process data from NASA's Earth Observing System (EOS) Aqua and Terra, Joint Polar Satellite System (JPSS), Suomi-NPP, NOAA's Polar Orbiting Environmental Satellites and EUMETSAT Polar System satellites. Please see the eOsphere VxEos brochure for further details.

Since 2007 eOsphere Limited (formerly Vexcel UK) has successfully delivered the VxEos Ground System to customers in locations throughout the world, including: China, China, India, Mongolia, UK, Iraq, Sudan, Malaysia, Indonesia, Vietnam and Greece (see map).     

The eOsphere ground station delivered to the Mongolian Ministry of Nature and Environment provides an excellent example of how remote sensing can be used to serve a large country (1,564,116 km2) which relies heavily on its natural land resources. A publication by Dr. Erdenetuya has described how their VxEos ground station is being used as a part of the Mongolian National Geo-Information Centre for Natural Resources Management programme to monitor drought, desertification, fires, snow, land cover, biomass for pasture.

Other applications include fires hot-spot detection, as well as the detection of smoke and volcanic ash, and oceanographic applications such as ocean sea surface temperature and ocean quality issues including sediment and chlorophyll monitoring.

Basic components of the system include a parabolic reflector, pedestal, RF/IF electronics, data capture, processing and visualisation system and ground system control software to automate the process of scheduling tracking, reception, processing and archiving of data.

Features and benefits

- Affordable turnkey solution for reception and processing of EOS Terra and Aqua MODIS and future planned NPP and NPOESS satellite data built on eOsphere's proven ground station technology.   
X-Y pedestal with no overhead cone-of-silence for complete hemispherical coverage. Low slew rates minimise wear and tear on gearboxes and mechanical components and therefore reduce maintenance costs.
- Program track, using NORAD two-line elements and orbital model, with optional auto-track.  
Optional sandwich foam core radome, hydrolam coated, impedance matched for reception of X-band transmissions around 8.2 GHz.
- Compact design using drive-bay receiver and plug-in data capture cards – no rack-mounted equipment.
- High specification, dual processor, off-the-shelf PC workstations running Linux or MS Windows.  Use of off-the-shelf components reduces maintenance costs.
- Fully automated scheduling, tracking, reception processing and archiving, completely configurable through the use of processing schedules and scripts.
- User friendly graphical user interfaces for all aspects of configuration, processing and visualisation of MODIS and other data.
- Choice of standard NASA GSFC, IMAPP or SeaDAS L0, L1 and L2 processors and data products.
- Import of NASA GSFC, IMAPP and SeaDAS archived data products.
- Automated or manual image re-projection and mosaicing to user-definable geocoded areas of interest in a number of different standard map projections.
- Integrated, fully featured image viewer for visualisation and processing of received imagery, including:

- Multiple image windows for concurrent display of different images or channels,
- Grey scale or false colour composite display, both as single frames and as animation sequences,
- Interactive real-time zooming and panning of displayed imagery,
- Re-projection to standard map areas,
- Contrast & colour palette enhancements,
- Statistical measures and plots,
- Convolution filters,
- User definable vector, symbol and text annotations,
- Geographic feature vector overlays and basemap underlays,
- Export to standard bitmap formats (PNG, JPG, GeoTIFF etc.).

- Programmers API for interfacing to received data and system libraries.
