All PNT/GNSS & Navigation Subsystems

The Dionysos Satellite Observatory (DSO) of the School of Rural, Surveying and Geoinformatics Engineering at the National Technical University of Athens (NTUA) is one of Greece’s key research infrastructures in space geodesy, satellite positioning and geodetic reference systems. Established in the late 1960s, it supports research and education in GNSS, satellite geodesy, crustal deformation, reference frames, tide-gauge monitoring and Earth dynamics. DSO operates a permanent GNSS network across southern Greece, contributes geodetic solutions to European reference-frame activities such as EUREF, and hosts specialised satellite geodesy infrastructure. Within the space ecosystem, its capabilities are directly relevant to precise positioning, navigation and timing, Earth observation geodesy, ground-segment infrastructure and monitoring of geophysical processes using satellite measurements.

Loctio is disrupting the positioning capabilities of IoT devices by combining two technology approach-es. It fuses multiple positioning signals like GNSS, LEO PNT & 5G and migrates the computationally inten-sive calculations to the Cloud or Edge. In this manner, accurate, ubiquitous, secure, and ultra-low power positioning allows the deployment of numerous IoT devices. Now this is not impossible due to power and processing resources limitations. This will be offered as a Location as a Service (LaaS) framework. Loctio’s business pertains to the financially prosperous low-power asset tracking market that yielded €4.5B in rev-enues during 2019 and is projected to reach €30B by 2029. Moreover, the outlook foresees more than 550M low-power asset trackers operating in the field in the same year. Loctio is willing to make available its LaaS framework through subscriptions to logistics, mobility/transportation, surveillance, utilities, and insurance companies deploying millions of IoT devices that need accurate, secure, and ubiquitous outdoor and indoor positioning without sacrificing battery longevity. Hence, recurring revenues from the LaaS comprise the prime revenue stream that is anticipated to bring in tens of millions of revenues after 2024.

Pollux Tech develops a downstream LEO-enabled safety infrastructure layer integrating GNSS positioning, satellite communications, and maritime regulatory frameworks for global operations. Its goal is to establish a continuous, human-centric satellite distress layer within existing maritime safety governance structures. The system introduces a complementary safety layer within existing maritime regulatory frameworks (IMO / SOLAS), leveraging Low-Earth-Orbit (LEO) satellite connectivity to enhance Search and Rescue (SAR) response efficiency and operational resilience.
