INTECS has acquired a unique expertise in Europe on “Software Defined Radio” (SDR) systems applied to Satellite Navigation.
INTECS employes such technologies for mobile terminals (based on NavCom technologies) and within space programmes like GALILEO (ESA), MIOSAT (ASI) and technological studies such as “Micro-satellites Formation“ (ASI).


These projects are developed according to the ECSS standards for the space programmes.

Satellite Navigation Applications

PossybliCom (Positioning System for Blind)
PossybliCom is a mobile device for visually impaired people supporting pedestrian navigation and giving indications on the surrounding and additional services.
PossiblyCom integrates the information received from numerous Navigation and Communication devices by means of  software components capable of correlating in an intelligent way the information received from the various sources. The hardware devices used are:

1 – Mobile Terminal (Smartphone or PDA)  with the following connections: GSM/GPRS/UMTS, Bluetooth and Wi-FI
2 – GPS Receiver (compatible with EGNOS and GALILEO);
3 - Inertial unit and magnetic compass
4 – Connection to the SISNeT

There are currently in-progress developments and adaptations (shape and weight) to the product in order to improve usability.


GALILEO Ground System Validation Tests
INTECS participates to the “Local Test Station” project providing analysis and measurement tools of the GALILEO signal characteristics to support the “GALILEO System Integration & Validation” activities.


Software Defined Radio for Satellite Navigation
Since 2005, INTECS employes “Software Defined Radio” technology  applied to Satellitare Navigation signals capable of integrating GPS, EGNOS and the GALILEO signal (today available as an experimental service). Such systems are developed on standard platforms and are able to receive and digitize GALILEO and GPS signals to obtain a unique positioning information.
Such instruments are currently used within a number of systems, such as the “Galileo Test Range” (permanent laboratory for GALILEO signal validation), and the GALILEO Ground Segment Integration & Validation.


Software Receiver On-Board Satellite and Navigation Applications
INTECS participates to an ASI project (leaded by Thales Alenia Space) related to the study and analysis of new missions based on “Microsatellites Formations“ for Earth Observation. In this project the use of a Software Receiver is proposed for On-Board Satellite navigation applications.


Furthermore INTECS participates to the MIOSAT program on the Payload for Satellite Navigation based on techniques of Software Defined Radio.
