DSD-INT 2018 High Altitude Pseudo-Satellites for monitoring and crisis management - Bos

  1. 1. Delft, 15 November 2018 High Altitude Pseudo-Satellites for monitoring and crisis management a feasibility study DSD-INT 2018 Data Science Symposium Chris Bremmer, Rogier Westerhoff, Marco de Kleine, Liduin Bos- Burgering
  2. 2. Content Introduction - Back…to the future HAPS in general: Specs Satellites vs HAPS Platform types Sensors and resolution HAPS applications Future prospects / timeline Conclusions Room for discussion 15 November 2018
  3. 3. Back… to the Future •First stratospheric flights using pressurized balloons 1930s •First aircrafts able to reach stratospheric altitudes 1950-1960 •First experimental projects for HAPS research 1969 •Launch projects aimed to analyze potential HAPS applications 1990-2000 •Launch projects performed by a.o. Google, Facebook, Airbus and WorldView 2014-2018 15 November 2018 Source: Rodrigez et al. (2017) – HAPS4ESA When was the first stratospheric flight reported with a HAPS forerunner? Any guesses?
  4. 4. HAPS - general Fast developing ESA: HAPS4ESA conference 2017 Maritime security/border surveillance and Air quality High variety of sensors: 30-50 km field-of-view Fills gaps between: Airplanes Satellites Drones 15 November 2018
  5. 5. HAPS - Specs 15 November 2018 Quasi-stationary airships or aircrafts Altitude: ~20 km Solar powered
  6. 6. Satellites or HAPS? HAPS Satellites Altitude ~20 km >~180 km Telecommunications link budget Low High Power consumption Low High Signal latency Less More Round-trip delay Less More Deployment in terms of development and launch Rapidly deployable and comparatively less expensive Significant time and monetary resources Landing for maintenance or mounting of a different payload Possible Impossible 15 November 2018

  12. 12. Conclusions HAPS are seriously explored in the space sector and will be deployed within 3 – 4 years Hyperspectral possible already – SAR very promising Opportunities for Deltares in flood management and environmental monitoring: Incorporate HAPS-data stream in operational flood forecasting Dedicated field survey for validation of models Follow-up scenarios: A. Wait and see B. Review for RWS C. Prepare for RWS-demonstration – Airbus or ESA D. Go international 15 November 2018
