We aim to improve the quality of our Earth
by understanding the nature of its changes


Research and services provider enterprise in the Earth Observation field


isardSAT is an R&D enterprise that provides services and solutions in the Earth Observation field. We develop projects that require the knowledge of the system, which are led by engineers, and projects that require a deeper knowledge of the final product, led by scientists.

Science & Technology

isardSAT carries out scientific-technologic projects in the Earth Observation field, developing on-board and on-ground algorithms to process microwave instruments data.

Scientific Applications

isardSAT performs studies for scientific applications with the data obtained by Earth Observation instruments. Application projects revolve around different hydrological applications.


isardSAT develops customised services that benefit from the usage of Earth Observation data. We provide final and complete products: we start by defining the specs and designing the final solution, and end up delivering and supporting our operational code to the customers. We also improve existing services by the addition of EO data into our partner's algorithms, adding value to their solutions as an EO-specialist trusted partner.


isardSAT is involved in the design, calibration and maintenance of civil remote sensing instruments, it means, from the development of algorithms for data processing to calibration and maintenance after the launch. Finally, isardSAT performs studies for scientific applications with the data acquired by these instruments and develops customised services using EO data.


The data as acquired by an instrument are not of any use for scientists. Scientists need these data to be transformed into physical variables. The process between the data as acquired by the instrument and the data as used by the scientist require the development of physical and engineering based algorithms, which also includes the instrumental corrections (see instrumental calibration section).

In particular, isardSAT’s main expertise is in the first levels of instrument processing, from the instruments source packets (Level 0 / Level 1 processing) to retracking algorithms for Level 2 processing.


Validation is the process of assessing, by independent means, the quality of the data products derived from satellite instrument measurements.

Geophysical products are generated from satellite data by applying an algorithm that is either physically or empirically based. Comparing the retrieved products, and their trends with in-situ observations or model outputs is an important part of the process to assess and document the reliability of given retrieval algorithms in deriving these products as well as to define its domain of applicability.

For many products validation is a complex problem since the comparison between products derived from satellite measurements and independent reference products often from in situ measurements is subject to several errors: (1) an inherent satellite-derived product error, (2) the error in the reference data, and (3) the error introduced by the comparison methodology, often due to non-collocation in time and space.

Validation of satellite-derived parameters and products can be carried out using the following sources:

  • Surface-based in-situ measurements
  • Surface-based remote sensing measurements
  • Model comparison and assimilation
  • Other satellite-derived or blended products of a similar type


Calibration is the process of quantitatively defining the satellite instrument response to known, controlled signal inputs. Instrument calibration is critical for any higher-level data processing, especially for deriving quantitative products or when data from different instruments need to be merged. For climate applications, the requirement for accurate calibration is particularly stringent since detection of small trends over long periods requires comparability of different instruments flown on different satellites at different times. Building homogeneous climate data records is contingent on very good calibration and error characterisation.

Satellite instrument calibration should take into account all phases of an instrument’s lifetime: from design and pre-launch phases to post-launch, and in-orbit operations.


The toolboxes are widely used in the remote sensing community in order to easily open and visualise Earth Observation data. They include basic functionalities to display optical or SAR images over the Earth or plot different variables along time. They could also include more complex functionalities to process some parameters on a different way than they are normally processed by the official processors and use them in research activities.

Toolboxes can be internal scripts that companies run themselves to test their research studies or can be free open source developed and distributed from the space agencies to the scientific community. This is the case of the Sentinel Toolboxes, developed by ESA under the Scientific Exploitation of Operational Missions (SEOM) program inheriting the functionalities of the historical toolboxes.

Dissemination & Outreach

This activity includes different tasks with the objective to inform and involve the wider community in each particular project:

  • Promote the project outputs within the relevant scientific and operational communities
  • Present the project results at scientific meetings.
  • Establish and mantain the project web page.
  • Submit  papers to international peer-reviewed journal(s), publishing the results of the project.
  • Produce project Brochures and other outreach material.
  • Create a profile of the project on social networks and post relevant information.
  • Organise seminars or workshops

Isardsat Logo

isardSAT was founded in 2006 in Barcelona with the mission to improve the knowledge of our planet Earth through Remote Sensing. isardSAT develops engineering and scientific projects with the objective of becoming the leading company in active and passive microwave remote sensing and preferred partner in the Earth Observation research field.

The years-long experience in the remote sensing field and its scientific applications has provided isardSAT with a large number of professional relationships and contacts within the international community, consolidating isardSAT as the leading enterprise in the first processing levels of altimetry data of European satellites.

isardSAT UK was opened in April 2013 in Guildford, at the Surrey Research Park. As a member of the Surrey Space Incubator, the company has rapidly grown and is hosting the leading team implementing the algorithms and processors developed by the company researchers.

isardSAT Poland was opened in August 2013 in Warszawa. Nowadays the company is based in Gdynia, where it is leading our research in altimetry-based Ocean Current studies.
