ESA, Verification of Small Satellite Market Development Concepts for Commercial Transportable Ground Station Operators – GS (2020 – 2022)
Space-SI has developed a mobile ground station for satellite communications, which will enable satellite operators and GIS service providers to perform not only the classic applications but also to interactively control satellites and transfer data in real or near real time. The goal of the project is to establish close cooperation between the ground station developer (Space-SI), satellite operators, and GIS service providers. With selected operators and GIS service providers we formulated the requirements of individual products and verified them through testing. An assessment of the market potential and expansion of the proposed solutions on the markets of space technologies and applications was carried out.
ESA, Enhanced Scientific Data Acquisition for ESA M5 THESEUS Mission – eTezej (2020 – 2021)
The main objective of the project is to support the Phase A study of the ESA M5 Theseus space mission by exploring the possibilities of how scientific data acquisition from the Theseus satellite can be supported by the STREAM ground station system. With applying this solution to some additional nodes in the equatorial network the scientific community could benefit by gaining additional opportunities to observe gamma-ray bursts in real time, reducing delays and increasing the transmission capacity of useful data of the Theseus mission. Having several ground stations available that can replace each other in the event of a failure of one of them would increase the reliability of the network. Additional nodes proposed by Space-SI will be fully aligned with Theseus’ core satellite communications technologies, operational requirements, data acquisition, processing and transmission processes.
A set of selection criteria is defined to obtain the most cost-effective solutions to increase data transfer and backup capacity and real-time, low-latency scientific data acquisition capabilities. With them, we will objectively compare the potentials of candidate earth station locations in the equatorial belt.
ESA, Novel EO data for improved agricultural drought impact forecasting in the Pannonian basin – DryPan (2019 – 2021)
The Pannonian basin is the western most part of the Eurasian steppes zone and was dominated by forest steppes and then over centuries used as grasslands. Nowadays, it is one of the largest agricultural regions in Europe. Because of the low precipitation, the region relies on the surrounding mountains as the key source of water. The objectives of the DryPan project are to:
- develop and validate a set of novel EO-based products and enhanced data sets dedicated to characterise drought processes in the Pannonian basin;
- foster new scientific results, where space technology may provide a valuable input;
- promote the use of advanced EO datasets for Drought Early Warning and facilitating access; and
- develop a roadmap identifying additional science priorities.
We will further develop different products, such as forecasts of crop yields, forecast anomalies, drought characterisation and compound events. The role of the SPACE-SI is to provide a web site exploiting advanced data access and visualisation tools. Other partners in the project are EODC, TUV and CzechGlobe.

UIA, APPLAUSE (2017 – 2020)
The project APPLAUSE (Alien PLAnt SpEcies ) – from harmful to useful with citizens’ led activities addresses unsolved questions with regard to invasive alien plant species in terms of the zero‑waste approach and circular economy. At present we are composting or incinerating these plants, and with the pilot project for processing plants into paper at a semi‑industrial level we have proven that they can be utilised for other useful purposes. The proposed system of managing invasive foreign plants is based on education and cooperation with the citizens of Ljubljana and three principles of operation:
- »Do it yourself«,
- »Process with us« and
- »Bring to the collection centre
We want to make it easier for the citizens of Ljubljana to recognise invasive non-native plant species on their own and then remove and process them into useful products. If they do not want to do that by themselves they will be able to go to the newly planned re-use centre where we can process them together in workshops or they can simply bring them to the new collection centre where project partners can process them in to useful products and then sell them.
Interreg Danube, project DriDanube – Drought Risk in the Danube Region (2017-2019)

In MARTINA programme the consotium of 16 partners from Slovenia will develop a high-strength steels and aluminum alloys with the aim of achieving material properties which are essential for new applications in the automotive industry to reduce the weight of vehicles and related CO2 footprint and energy consumption during production and the use of vehicles. In the case of multicomponent materials we will take advantage of the ease of use of plastic materials and specific properties of metallic materials. With the introduction of new materials we will develop advanced manufacturing technologies and transformation, which will set new requirements for tools and tool steels. In addition to the properties of tool steels they will challenge even the correct distribution of these features in the tool and sensors, allowing control of the operating conditions of the tool. Due to the increasingly complex shapes of tools, we studied the program procedures innovative 3D printing tools. The result of the program will be prototypes of tool steels. Their properties and the suitability of 3D printing tools will be tested on tools prototypes. The result of the program will also be prototypes visokotrnostnih steel kneading and molding aluminum alloys and prototypes of new multicomponent materials with specific properties. Their properties will be tested and optimized on sample cases, components of the car ilske and electrical industry, which is the horizontal links.
SRA J6-7085 Regional project Chactún: Research of the archeological landscape in the Central Maya Lowlands (2016-2018)
The project includes the extension of the archaeological research carried out in the eastern Mexican state of Campeche in 2013 and 2014, when the remains of three major Mayan city centers Chactún, Tamchén Lagunita were discovered and documentedand.

We will process the raw lidar data taking into account the specific needs of the research and the peculitarities of the environment. Analysis and interpretation of lidar data supplemented with those obtained with field verifications will enable us to determine the extent of settlements and the distribution and characteristics of other types of anthropogenic elements and to identify any correlations with the specificities of the natural environment.

SRA J2-6777 Automatic object-oriented land cover classification of optical remote sensing data (2014-2017)
Although the potential for the use of satellite imagery is well demonstrated, their actual exploitation has not increased in recent years. The main reasons for this, other than the price, are time-consuming and complex pre-processing, and a complicated classification procedure. Due to increase in spatial and spectral resolution of satellite imagery pixel-based classification has been replaced almost entirely by object-based classification. Potential of its main steps – i.e. segmentation and classification – is not yet fully studied, however. The main aim of the proposed project is to develop an automatic procedure for geometric and radiometric correction of satellite images, and production of a land cover map (vector layer) that can be used directly by end-users in their analyses using geographic information systems (GIS).

Compared to competitive semiconductor technology, ferroelectrics have a fast response exhibit low-leakage currents resulting in lower power dissipation and they represent a cost-effective solution. In addition, their functional response is irradiation-resistant, which is strongly beneficial for space applications.

The layers were irradiated with doses of neutrons and gamma rays, which go beyond the value that could be obtained in the orbits of earth satellites. We found out that with With designing layer microstructue stable dielectric properties in both kHz as in the GHz range can be achieved. The antenna system has proved suitable functional properties for use in satellites.
