GARISS, Mission accomplished!

Qascom has successfully achieved the first positioning fix on board the International Space Station combining the high accuracy L5 band signals of the US GPS and the European Galileo Global Navigation Satellite Systems as part of the Galileo Receiver for the ISS (GARISS) mission.

The project, started in 2016, is a joint initiative of NASA and ESA that have started a cooperation for the demonstration of the benefits of the dual constellation, GPS plus GALILEO, space navigation.

GARISS mission has introduced innovative concepts for space positioning exploiting the Software Defined radio technology installed in the Space Communication and Navigation (SCaN) Test Bed on the ISS since 2012, and Qascom software solution that has been recently uploaded in space.

The waveform, combination of software and firmware, has been developed according to the Space Telecommunications Radio System (STRS) framework that has been initiated by NASA to define a new standard architecture for space-qualified radios in support of future missions.

The STRS allows the developers to prepare software in a modular, portable, reconfigurable and reusable way.

The ISS on orbit operations are being jointly coordinated by Qascom engineers in Italy and the NASA Mission and Control center at the Glenn Research Center (GRC) in Cleveland. The GARISS Telemetry data are then downloaded through the NASA Space Network and validated in Qascom laboratories. Multiple configurations have been tested to collect GNSS measurements different modes: GPS only, Galileo only and GPS – Galileo combined.

Samuele Fantinato and Andrea Dalla Chiara chief System Engineers of the project report that, “during the in SPACE experiments, the GARISS software has acquired and tracked GPS and Galileo signals exploiting an advanced assisted acquisition mode for space, similar to the technologies currently used in the smartphones: satellites and ISS orbit data aiding have been uploaded from ground stations in order to achieve a faster position fix and to maximize the availability of ISS trajectory data”.

Samuele Fantinato adds “the mission has been very challenging and we are now all excited for the excellent results and the cooperation with ESA and NASA. We intend to exploit more the advanced processing technologies in future evolutions of Qascom space receiver”.

Oscar Pozzobon, Director of Qascom and GARISS Mission Manager says “It has been a mission impossible but we all made it: We have experienced software and hardware failures, we had to construct replicas of the system to mimic any space equipment issues. We achieved the first ever L5 only GPS and Galileo positioning on a very challenging environment. This has demonstrated the excellence of the team in Qascom, NASA and ESA”

For Qascom, GARISS has been the first step in the development of an innovative Space GNSS platform based of Software Defined Radio Technology with advanced features including the Configurability for Multi Applications and the support to future Galileo authentication services.

Galileo Receiver for the ISS

Qascom is developing for NASA and ESA GARISS, a software defined space GNSS receiver for the International Space Station.

The Space Communications and Navigation (SCaN) is a facility developed by NASA and hosted on board the International Space Station (ISS) on an external truss since 2013.

It has the objective of testing navigation and communication experimentations with a Software Defined Radio (SDR) approach, which permits software updates for testing new experimentations.

NASA has developed the Space Telecommunications Radio System (STRS) architecture standard for SDRs used in space and ground-based platforms to provide commonality among radio developments to provide enhanced capability. The hardware is equipped with both L band front-end radios and the NASA space network communicates with it using S-band, Ku-band and Ka-band links.

In May 2016 Qascom started GARISS (GPS and Galileo Receiver for the ISS), an activity of experimentation in collaboration with ESA and NASA that has the objective to develop and validate the acquisition and processing of combined GPS and Galileo signals on board the ISS SCaN testbed.

The preliminary results include GPS and Galileo processing from space signals, the challenges and trade off decisions, the high level STRS architecture and foreseen experimentation campaign. Detailed results from the test campaigns are expected in 2018.

Inside GNSS, Interference Localization from Space

Qascom has published two papers on two consecutive issues of Inside GNSS (Nov/Dec 2016 and Jan/Feb 2017) on the topic of interference localization from space.

Radio frequency interference causes the satellite industry to lose millions of dollars per year due to detrimental effects, ranging from a degradation in the quality of service to the complete loss of service. As a consequence, it is becoming critically important to design space systems that are able to localize the source of interference, allowing actions that can prevent future repetitions of similar behaviors.

The first of the two articles discusses the theoretical aspects associated with single-interferer localization approaches, describing how to extract those features providing information on the interference source location from the received interference signal itself, and how to compute a position fix by merging the collected information.

The second of the two articles focuses on practical aspects associated with single-interferer localization approaches. It describes two different types of localization architectures, ground-based and space-based, discussing simulation results for each and showing the performance that such architectures can achieve in specific scenarios Download Brochure

Qascom's hi-tech for Nasa and Esa

NASA, ESA and Qascom are collaborating to build the first GPS and Galileo receiver to be tested on board the International Space Station (ISS) Space Communications and Navigation (SCaN) Testbed.

QSCaN is a payload developed by NASA that has been hosted on board the International Space Station on an external truss since late 2012. The goal is to test experiments on navigation and on communications with a software-based approach, or Software Defined Radio (SDR) that allows easy system upgrades.

In May 2016, Qascom was awarded with the “GPS and Galileo Receiver for the ISS” (GARISS), in support of an experiment that aims to develop and validate the acquisition and processing of the combined GPS and Galileo signals on the Station: it is also the first attempt to develop a software scan through an international collaboration between the US and Europe.

To date, the combined team of NASA, ESA and Qascom has acquired and successfully processed GPS and Galileo signals on two separate frequencies. One of the challenges is indeed the acquisition of radio navigation signals in space using the limited resources of the instrument. In addition, the big difference between the orbital dynamics of the station, which in low orbit travels at a speed of 27,600 km / h, and the dynamics of the system GPS and Galileo's medium Earth orbit, creates additional complexity.

"The importance of the project with ESA and NASA" - says mission manager Oscar Pozzobon - "is given by the first trial that the two space agencies are jointly testing the American GPS system with the European system Galileo into space, respectively. Both represent the future of satellite navigation: 14 Galileo satellites already in orbit and another 4 ready for launch in November, the two positioning systems to ensure all land applications, including those based on smartphones. Test of the combined use in space is of strategic importance for all future space missions. "

Advanced Satellite Multimedia Systems Conference and Signal Processing for Space Communications Workshop, ASMS/SPSC 2016, Palma de Mallorca (Spain)

Qascom presented an abstract entitled Satellite-Based Interference Localization Techniques.
Radio Frequency Interference (RFI) represents a serious threat for the satellite industry: it is one of the most important operational problem affecting customer services on geostationary satellites, causing the SATCOM it is also a major threat to navigation systems and their users.

In this context, it is becoming of critical importance to design space systems that are able to localize the interference source, allowing the competent authorities to react quickly and prevent future repetitions of similar behaviours.

This tutorial gave an overview of localization approaches that are based on processing the signal sent by a target, covering aspects such as:

1) the extraction of basic features from the received signal, which define loci of points within which the target may be located;
2) the computation of a position fix from multiple loci of points;
3) the challenges associated to a satellite based localization approach, with particular emphasis to a single satellite architecture.

In addition to it, the localization results obtained with a software simulator developed by Qascom have been shown and discussed.
