The rich biochemical information
contained within the hyperspectral data
provides better measurements and estimates
of vegetation properties required
to evaluate crop growth stages and
health conditions. It also enables the
identification of inner-pixel variations,
enforces the detection of under-representative
crop species, and differentiates
parcels based on agricultural practices.
The highly accurate spectral data
of Hyperfield would allow European
stakeholders and Global service providers
to automatically map land cover
changes and crops, improve yield forecasting,
and evaluate biomass volume
and carbon content are necessary to address
climate change and food security.
By supplying daily hyperspectral measurements
to Copernicus, Hyperfield
will enrich and extend the optical-based
geophysical and biochemical parameters
derived from Sentinel and other available
Earth Observation instruments and support
the development of global services,
beyond crop monitoring and land use
mapping. It will enhance the extraction
of biogeochemical characteristics of the
global oceans and regional seas, improve
the monitoring of water quality, enable
the identification of harmful algae species,
and extend Blue Economy applications
including aquaculture and blue carbon.
Hyperspectral data can be used to
produce accurate bathymetry maps (up
to 30 m depth) and seafloor substrates
(such as sand, rock, and coral) of coastal
areas by analyzing the intrinsic optical
properties of the water column in different
spectral wavelengths.
It can improve the monitoring of sea
and land ice surfaces in Arctic regions by
providing accurate albedo (reflectivity)
measurements and characterizing permafrost
composition (e.g. ice, organic matter,
and mineral content) based on spectral
information. Additionally, Hyperfield
data has the potential to advance the
measurement of climate change indicators
and the monitoring of atmospheric
pollutants like methane and carbon dioxide.
By delivering information pertinent
to support progress in biomass measurement,
biodiversity mapping, and accurate
change detection in forest and urban areas,
Hyperfield will improve the response
of Copernicus services to health-related
environmental phenomena.

Kuva Space also aims to support Copernicus
safety and security services by
providing near real-time observation
of conflict areas and hazard events and
monitoring their impacts and recovery
processes, by providing spectral information
pertinent to these activities. To
achieve this goal, Kuva Space has also
the intention to offer tasking capacity to
Copernicus for ensuring the provision
of data to disaster management, security
and defense, and climate change services.
Particularly, Hyperfield's unique
imaging technology will enable four
acquisition modes: optimized scanning,
collecting stereo images in off-nadir observation,
producing enhanced-resolution
images via micromovements, and
" staring on " a specific spot for a longer
period of time.
By extending the integration time
during the staring mode, the signalto-noise
ratio can be improved significantly
by a few hundred percent, and
data quality can be enhanced to meet
security requirements. Additionally,
the company plans to integrate GPUs
into its second-generation satellites to
enable AI-based calibration and processing
on board the satellite. This will
allow Kuva Space to align all the spectral
bands, create hyperspectral data
cubes, detect scenes affected by clouds,
and compress the data to reduce volume
and increase the amount of data
that can be transmitted to a network of
ground stations.
Furthermore, the company seeks to
develop its
Sat-to-Sat and Sat-to-IoT
mobile communications to accelerate
the delivery of analytic products to
end users in real-time through secured
API to operational platforms. A good
example of how important such a capacity
is to security services is the detection
and rediscovery of suspicious
vessels. The marine surveillance services
monitor and track vessels based
on their automatic identification systems
(AIS) and radio frequency information
(RFI).
It is very well known that criminal,
stealth or dark vessels tend to turn AIS
off and do not transmit RF signals.
In security operational systems, the
absence of these signals produces an
alert. With Hyperspectral, these vessels
can be detected based on their specCATIONIC

tral signatures, and then automatically
rediscovered and tracked when they
approach ports for parking and must
turn on their AIS systems. In near real-time,
the automatic processing on
board the satellite provides the vessel's
position coordinates to mobile phones
or operational platforms through secured
channels.
During the next five years, the European
Space Agency will evaluate the
quality of Hyperfield data with several
global use cases to ensure that the satellite
data meets the technical, operational,
and security requirements of
Copernicus. Successful evaluation will
grant Kuva Space a commercial contract
to provide hyperspectral data to
the Copernicus program on a permanent
basis.
