About us

Star2Earth is a Starlab business unit focusing on delivery of Earth Observation products and downstream services. Star2Earth mission is to transform science into technologies with a profound positive impact on society. Our vision is to make science more useful, alive, vibrant, and faster.

Starlab

At Star2Earth we provide advanced solutions integrating Earth Observation augmented services and products into the decision chain for more competitive and sustainable operations. Our clients include international and national enterprises and administrations in the water management, energy, agriculture and environmental management sectors. Star2Earth is a key service provider and high-tech consultancy deeply committed to maximising our clients’ efficiency and general resource optimization.

Technologies:

At Star2earth we have a track record in the use of consolidated as well as cutting edge technology to solve our clients’ needs. Our expertise in the processing of satellite data allows us to extract relevant information to be included in our products and services. For the creation of space applications we carry out some of the following activities:

  • New algorithms and models for Earth Observation:
  • Development and tailoring of algorithms and signal processing techniques for ocean and land remote sensing.
  • Implementation of new models to enhance the capabilities of estimation of geophysical parameters and to enable the monitoring of new variables of interest.

At Starlab we are experts in the following technology:

Advanced Radar Systems (including SAR)

Our expertise in radar systems is mainly based, but not only, on Synthetic Aperture Radar (SAR). The key expertise of Starlab in this area includes mission analysis, design, and performance estimation of a wide number of radar concepts, including: interferometry, multi-dimensional parameter retrieval, and wide-swath coverage.

Global Navigation System of Systems Reflectometry (GNSS-R):

The use of Global Navigation Satellite Systems signals (GNSS) for Earth Observation is an evolving technology that allows a multi-purpose exploitation of navigation signals using their reflections on the Earth’s surface.

The instrument we have developed based in this technology is able to retrieve numerous geophysical parameters such as soil moisture, vegetation, ocean roughness or waves, topography).

Altimetry:

Starlab’s expertise in altimetry covers advanced mono-static space altimetry technical consulting. We are specialised in processing satellite altimeter high-resolution data and extracting relevant geophysical information, as well as providing assessment of on-board and on-ground processing techniques.

Optical data processing:

Nowadays, with satellite and aerial optical data we are able to gain sustainable knowledge about our planet’s condition and the use of its surface precisely and extensively. Some of the main areas of application of our optical data processing are agriculture, urban environments (through land use detection), marine environment, among others.

Our expertise provides well established, highly reliable and cost-effective solutions for data handling and processing services for different customer needs and design technologies that can be implemented using state-of-the-art IT technologies related to data reception, processing, backup, and service.

Satellite-based persistent scatterer interferometry*

Satellite-based Persistent Scatterer Interferometry (PSI) is a powerful remote sensing technique used to measure and monitor deformation of land, structures and infrastructures. The PSI technique requires a set of SAR images acquired over the same area. Its main products include a map of deformation velocity and a time series of deformation over the observed period. The technique can be used to monitor different types of deformation phenomena, like deformation of structures (e.g. buildings) and infrastructures (e.g. dikes, bridges, highways, etc.), land subsidence, landslides, tectonic and volcanic activities, among others.

Real-aperture-radar interferometry*

The Real-Aperture-Radar (RAR) interferometry is a ground-based remote sensing technique to measure the vibration characteristics of structures and infrastructures. The technique offers three interesting vibration monitoring capabilities: a very high sensitivity to displacements, up to a few microns; the capability to sample the vibrations in time at high frequencies; and all this is achieved by non-contact and easy-to-make remote sensing measurements. The technique at hand is based on a RAR device, which sends microwaves that propagate in the atmosphere, interact with the targets and return to the same sensor. It can be used to study the vibration characteristics of building, bridges, viaduct, towers, etc.

*The products and services based on these technologies are offered by Starlab in virtue of a framework agreement with the Geomatics Division of CTTC (Centre Tecnològic de Telecomunicacions de Catalunya)
