SATELLITES & MISSIONS

PRISMA

(PRecursore IperSpettrale della Missione Applicativa)

Prisma is the first European Satellite with hyperspectral instrument and panchromatic camera on board. The satellite was realized for the Italian Space Agency (ASI) by a consortium led by OHB Italia S.p.A. as Prime Contractor.

It was successfully launched atop a Vega launcher on 22nd March 2019 from Arianespace Spaceport in Kourou, French Guyana. Now PRISMA is in orbit (commissioning completed) and it is acquiring, downloading, processing, delivering fundamental images for monitoring our Planet. Since April 2020 free access to the system has been made available to the Users Community an average of five thousands spot images per month.


Activity carried out under ASI contract.

NAOS

(National Advanced Optical System)

It is an Earth Observation mission for Luxembourg Government. NAOS is a very high resolution optical satellite system developed by OHB Italia S.p.A. as the Prime Contractor.

NAOS contract is an end-to-end agreement for the provision both of the satellite and of its ground segment.

NAOS Space Segment:

  • Composed of one satellite, placed in Low Earth Orbit
  • Equipped with a very high-resolution optical camera

NAOS Ground Segment:

  • Characterized by a distributed architecture
  • All the relevant Centers are connected through a Ground Communication Network in order to allow system management

URANO CONSTELLATION

Urano constellation is composed of 57 Eaglet II mini-satellites with worldwide coverage and very small revisit time (every 30 min.).

Thanks to its frequency and definition characteristics, it offers a type of service currently unavailable worldwide.

The constellation will monitor climate changes, marine/land surveillance as well as enable security and emergency services.

Features:

N. of Satellites: 57
Orbit: SSO 467Km
Revisit time: 30min
Imaging Capacity: 100 – 400 (with polar station)
Payloads: optical/AIS
X Band: Data transmission to the Ground Segment until 100Mbps
Memory: 32GB
Dimension: 20cmx20cmx50cm
Mass: 25Kg
Operative Life: min. three years

COMET INTERCEPTOR

It is a new fast class ESA mission comprising three spacecrafts, with the target to visit a truly pristine comet or another interstellar object. It will offer a new insight into the evolution of comets as they migrate inwards from the periphery of the Solar System.

The mission comprises one main spacecraft and two small probes that will fly together towards a yet-to-be-discovered comet. The main spacecraft and the two probes will separate prior to arriving and intercepting the comet’s coma, each performing simultaneous measurements and offering the opportunity to perform science observations at multiple locations. In addition, they will carry complimentary remote sensing and in-situ measurement payloads to investigate the comet’s nucleus, its outgassing and trailing materials and the plasma environment. OHB Italia’s responsibilities, as prime contractor, are the mission analysis, system engineering, procurement, integration, testing and other important tasks.

HERA MISSION

The Mission is an international double-spacecraft collaboration NASA/ESA for planetary defence. Target is a binary asteroid system, the Didymos pair of near-Earth asteroids.

OHB Italia is responsible for system engineering support, harness, AIT support, Electrical Power Subsystem, Satellite EMC, charging and radiation analysis.

BIOMASS

Earth Explorer Mission of ESA for Biomass and Tropical Forest Observation (distribution, annual changes, links with Earth climate). Essential support to UN treaties on the reduction of emissions from deforestation and forest degradation.

It will carry the first P-band synthetic aperture radar, able to deliver accurate maps of tropical, temperate and boreal forest biomass.
