Role in the IGS
JPL hosts the IGS Central Bureau.
JPL also hosts an IGS analysis center (AC) which currently contributes rapid, final, and reprocessed GPS-only orbit and clock products to the IGS. JPL’s contributions are created using the multi-technique (GNSS, SLR, VLBI, DORIS) and multi-constellation GipsyX software processing package, which replaced GIPSY-OASIS in 2017. The JPL AC is currently in the process of transitioning to produce GPS+Galileo orbit and clock products and hopes to start delivering these to the IGS in the near future. JPL contributes to several IGS working groups and currently has an elected member of the IGS governing board.
Finally, JPL also hosts an Ionospheric Associate Analysis Centre (IAAC) contributing daily final and rapid Global Ionospheric Maps to the IGS Ionospheric Committee.
Institution Description
The Jet Propulsion Laboratory is a unique national research facility that carries out robotic space and Earth science missions. JPL helped open the Space Age by developing America’s first Earth-orbiting science satellite, creating the first successful interplanetary spacecraft, and sending robotic missions to study all the planets in the solar system as well as asteroids, comets and Earth’s moon. In addition to its missions, JPL developed and manages NASA’s Deep Space Network, a worldwide system of antennas that communicates with interplanetary spacecraft.
JPL is a federally funded research and development center managed for NASA by Caltech. From the long history of leaders drawn from the university’s faculty to joint programs and appointments, JPL’s intellectual environment and identity are profoundly shaped by its role as part of Caltech.
Today JPL continues its world-leading innovation, implementing programs in planetary exploration, Earth science, space-based astronomy and technology development, while applying its capabilities to technical and scientific problems of national significance. JPL technology developed to enable new missions is also applied on Earth to benefit our everyday lives.

Role in the IGS
The Astronomical Institute of the University of Bern (AIUB) hosts the CODE analysis center (AC) of the IGS. It is one of the leading ACs since the beginning contributing to the operational ultra-rapid, rapid, final series since the beginning of the IGS. The computation is mainly performed on the high-performance computing system of the University of Bern using the Bernese GNSS Software package.
A strength of the CODE AC are developments in the field of orbit models (e.g., the ECOM series is used by many of the AC groups). Since 2003 operational CODE products are computed based on GPS and GLONASS measurements; in 2019 Galileo has been added to the legacy rapid and ultra-rapid contributions. With this strong background in multi-GNSS processing, CODE is supporting the MGEX pilot project of the IGS with a five-system solution, including GPS, GLONASS, Galileo, BeiDou, and QZSS.
Members of the AIUB team contribute to various IGS working groups. In particular the chair of the Antenna Working Group is currently located at AIUB. Furthermore, AIUB members have been elected to the Governing Board and to the IGS Executive Committee.

The satellite geodesy research group has a well-established experience on geodetic applications of Global Navigation Satellite Systems (GNSS), in particular on precise orbit determinations of GNSS satellites and low earth orbiting satellites (LEO) tracked by GNSS. A specific focus is also put to satellites dedicated to gravity field determination. In this context AIUB is hosting the COST-G coordination, a product center of IAG’s International Gravity Field Service (IGFS) combining time-variable gravity field solutions from various analysis centers. In addition, the research group is active in processing SLR measurements for various purposes.

Members of the AIUB team contribute to various working groups. In particular the president of IAG’s Commission-2 (Gravity Field) is currently located at AIUB. Furthermore AIUB members have been elected to the IAG Executive Committee and to the GGOS Executive Committee.
Role in the IGS
The Center for Orbit Determination in Europe (CODE) acts as one of the global analysis centers (ACs) of the IGS since 1992, the beginning of the IGS pilot phase. The operational products are generated at AIUB whereas the computations for the reprocessing campaigns are performed at IAPG/TUM. The Bernese GNSS Software is used for all activities at CODE.
Apart from GNSS satellite orbit, receiver and satellite clock correction including code and phase biases (e.g., needed for ambiguity resolution in a PPP processing), ERP, coordinate products also troposphere corrections and various ionosphere models are computed and made available. Since May 2003 the operational CODE solution is generated as a combined GPS and GLONASS solution. In September 2019 CODE started to include Galileo to the operational rapid and ultra-rapid series.
Members from the institutions of the CODE consortium support numerous of the IGS working groups, chair two of the working groups, contribute to the IGS Governing Board and Executive Committee.
Institution Description
The Center for Orbit Determination in Europe (CODE) is a joint venture between
- the Astronomical Institute of the University of Bern (AIUB, Bern, Switzerland)

- the Federal Agency for Cartography and Geodesy (BKG. Frankfurt a. M., Germany), and
- the Institute for Astronomical and Physical Geodesy, Technical University of Munich (IAPG/TUM, Munich, Germany).
The collaboration within the CODE consortium goes much beyond the IGS activities. It includes activities in the frame of EUREF – the European densification of the global reference frame – but also other space geodetic techniques like Very Long Baseline Interferometry (VLBI) and Satellite Laser Ranging (SLR), e.g., where the consistency of the BKG-contribution to the ILRS is made as consistent as possible to the CODE IGS solution.
The two contributing national mapping agencies use the CODE products and the software for their own reference frame maintenance activities. A consistent use of products and software enables a consistent alignment of international, European, and national reference frames. On the other hand, the academic institutions get input for their research activities

Institution Description
From ocean to land, and from outer space to the deepest ocean floors. The Norwegian Mapping Authority’s field of work is extensive and diverse. Geographical and ratified information are the common denominators when it comes to the tasks performed by the Norwegian Mapping Authority. This might include datasets that provide the basis for a map, place names, property boundaries or registered rights associated with a specific place. We collate, systemise, manage and communicate public geographical information.

GSI’s national GNSS CORS network, GEONET (GNSS Earth Observation Network System), plays a pivotal role in providing sustained access to the national geodetic datum with dense spatial coverage. GNSS CORSs, located approximately 20km apart, routinely obtain daily coordinates and constantly monitor the crustal deformation. The crustal deformation data is essential for maintaining geodetic datums in countries, such as Japan, where tectonic movements are active. Observation data and coordinate time series are publicly available. They support research activities in a wide range of scientific fields, as well as socioeconomic activities such as public surveying and location-based services.
