Mission Objectives:

The HY-2 satellite is an oceanographic remote sensing satellite series developed by China's National Satellite Ocean Application Service (NSOAS); four satellites are planned: HY-2A (2011), HY-2B (2018), HY-2C (TBD), HY-2D (TBD). The objective of HY-2 is to monitor the dynamic ocean environment with radar sensors to measure sea surface wind field, sea surface height and sea surface temperature. It will include a dual-frequency radar altimeter in Ku and C-bands, a Ku-band rotating scatterometer and microwave imager. The orbit is sun-synchronous: the first 2 years with a 14-day cycle, then one year with geodetic orbit (168-day cycle, 5-day approx. subcycle).

Mission Instrumentation:

HY-2A will have the following instrumentation onboard:

  • Micro-Wave Radiometer
  • Retroreflector Array
  • Ku-band Rotating Pencil-beam Scatterometer
  • Ku- and C-band Pulsed-Limited Nadir Radar Altimeter
  • GPS
