VINAG - Vision INS GNSS Integrated System for Space Navigation

Obiettivo

In poor visibility situations for a GNSS receiver (i.e in space applications for orbits higher of the GNSS satellites or on the ground applications -eg quadcopter- in low altitude in the presence of urban canyons) it can be difficult the acquisition and tracking of a sufficient number of GNSS satellites. However, a lower number of GNSS satellites can be used to improve the performance of a vision-based navigation system using this available and although limited GNSS pseudorange (and pseudorange rate) measurements. The goal of the project is the development of a vision based navigation system, assisted by inertial sensors (INS) and a GNSS receiver for precision space applications, such as "in orbit servicing", "debris removal", "landing and rovering for lunar exploration".

Attività nel progetto CIRA

The CIRA activities are:

- Review of the state-of- the-art technologies and systems that integrate measurement provided by vision systems, GNSS receiver, IMU (Inertial Measurement Unit) platforms with possible integration of Star Tracker .

- Design and development of an advanced sensor fusion algorithmic architecture.

- Development of the parametric modeling of an IMU platform.

- Fast-time verifications and support for real-time testing with HW-in-the-loop integrated system.

Programma:

From a programmatic point of view, the activities related to the VINAG project, in which the CIRA activities are included, can be divided into the following phases:

1. Definition of operational scenarios and related system requirements

2. Definition of subsystem requirements (i.e  GNSS receivers , IMU , etc ...)

3. Development of sensor fusion algorithms and verification tool

4. Numerical Verifications (Fast -Time and Real – Time)

The current status of the activities is: step 1 completed and step 2 and 3 on-going.

VINAG - Vision INS GNSS Integrated System for Space Navigation
On Board Systems and ATM
Thanks to a founding opportunity of the Italian Space Agency dedicated to Italian SMEs, the company Techno System Developments requested the CIRA support for the implementation of an innovative Navigation Unit for space platforms that integrates traditional inertial sensors (IMU, GNSS receiver) and cameras.
On Board Data System, Optics, Numerical Models (including Fast Time simulation), Optics-Optronics-Lasers-Image processing and data fusion
