Integrated Galileo Reference Infrastructure and technology development for height modernization

Register for the Final Presentation of the NAVISP EL3-024 Project: " Integrated Galileo Reference Infrastructure and technology development for height modernization (INGRIM)"

The INGRIM (Integrated Galileo Reference Infrastructure and technology development for height modernization) project targeted a complex solution to introduce multi-GNSS in geodetic height determination practice exploiting the synergies of multi-GNSS and InSAR. The approach offers modernized reference network infrastructure and digital database as alternative for the traditional leveling benchmarks, which can be maintained cost-efficiently using satellite technologies. The elaborated approach also understood as a quantum leap in geodesy generating semi-kinematic height reference, where the Lechner Knowledge Center was able to consider the ground motion in height determination.

In INGRIM, a pilot network comprising seven integrated multipurpose stations equipped with multi-GNSS CORS and InSAR corner reflectors was established. These stations are also part of the networked RTK service and are envisioned as the new generation of primary height benchmarks in the long term.

A new digital geodetic height reference was generated, combining the static geoid with high-resolution, time-variable ground motion data derived from GNSS and InSAR. This concept and database were successfully tested in field campaigns, demonstrating the superiority of the multi-GNSS and kinematic approach. The Lechner Knowledge Center accounted for ground motion over the past decades.

The INGRIM project became the flagship of the modernization of the Hungarian geodetic infrastructure. Thanks to the successful INGRIM demonstration the network extension process has already started, all of our CORS from building tops will be moved down to the ground. The new network and station concept will provide higher quality data and a resilient network prepared for extreme cases like the ongoing solar maximum with disturbed ionosphere. 

The project was part of NAVISP Element 3, aiming to support national PNT strategies by providing support per country and possibly per domain for the development and promotion of products, applications and services based on PNT systems to foster national and international cooperation.
