Water Resources Satellite
-
Objective
Develop water resources satellites (imaging and communication) and establish the infrastructure and application framework needed to monitor water-related disasters, such as floods and droughts.
-
Period
2022 – 2028
-
Contents
- Develop and launch payloads for water resources satellites (imaging and communication)
- Develop calibration and validation (Cal/Val) and application technologies for water resources satellites
- Establish an integrated satellite operations system and a ground operations center
Deliver services that help keep people safe from water-related hazards by establishing a wide-area water-disaster monitoring system that operates without interruption, 365 days a year.
- Secure satellites for wide-area monitoring of water resources and water-related disasters that are unaffected by day/night cycles or adverse weather.
- Stablish systems to collect hydrological data in real time and monitor rivers and dam watersheds using satellite imagery.
