Register for the Final Presentation of the NAVISP EL1 -045 Project " Multi-Layer PNT for SAR (HASARDS)”
The purpose of this project is to investigate the added value that HAPS could bring to SAR, through feasibility study and demonstration via simulations and field experiments.
Combining High Altitude Pseudo Satellite (HAPS) with multi-layer LEO/MEO/GEOSAR ranging would improve beacon localisation. HAPS can also be quickly moved over a specific location within the designated service area. Another HAPS benefit is the improved link budget, between 30 and 40 dB, depending on its altitude. Furthermore, TOA/FOA measurements with considerably increased SNR are expected to improve the independent localisation of distress beacons in challenging environments. The HAPS could also bring additional features to the SAR system such as augmented reality (e.g. real-time imaging superimposed with localization), shorter transmission path (e.g. signal directly redirected to rescue teams below), and direct georeferencing.
HASARDS project also addressed whether proposed enhancements could be either done by integrating the already existing beacon-MEOSAR link as an additional collaborating layer or acting as a standalone & new member of the COSPAS-SARSAT system. The most plausible scenario consists of regional HAPS layers designed and built to interact directly with Rescue Coordination Centres (RCC) rather than the COSPAS-SARSAT system. Rescue Coordination Centers could make use of the independent data products provided by the HAPS layer together with the traditional COSPAS-SARSAT services.
This project proposes an architecture and set of features to be embarked on a layer of HAPS deployed for the purpose of augmenting the search and rescue efforts in areas of interest such as migrant corridors.
The project was carried out in the scope of NAVISP Element 1, which is dedicated to technology innovation of the European industry in the wider PNT sector.
