ICEYE SAR Satellite Capabilities

The World's First SAR Satellite Under 100 kg in Launch Mass 

ICEYE has developed an innovative radar technology for under 100 kg satellites to better meet the needs of commercial and government customers. SAR technology and optimal resolution choices enable dramatically improved cost-effectiveness over traditional large-size radar satellites.

ICEYE SAR Image Quality Parameters

The following SAR Image quality parameters are indicative of ICEYE SAR sensors, which is representative for performance of satellites developed by ICEYE.

 

General Radiometric Performance

The ICEYE SAR processor compensates the following effects:

  • Range spread loss
  • Elevation antenna pattern
  • Effects of different azimuth and range bandwidths
  • Sensor settings variations ( receiver gain, transmit power, duty cycle)

Radiometric Accuracy

Relative Radiometric Accuracy is the standard deviation of the radiometric error of known targets within one data take. Contributions come from the antenna pattern, the pointing knowledge of the antenna pattern and drifts of the instrument during operation. The relative radiometric accuracy estimate is < 1 dB for Stripmap data.

 

Pixel Geolocation Accuracy

For satellite path oriented (SLC and GRD) products, the pixel geolocation accuracy is primarily determined by the system performance on orbit. For orthorectified and value added products, also the quality of DEM (particularly vertical accuracy) should be taken into account.

Predicted orbit is obtained using the latest post-processed GPS data propagated to the acquisition time. Rapid orbit is obtained as a result of post-processing of GPS data during the ground station pass and provided for processing / georeferencing of the imagery. Typical orbit accuracy levels of small SAR satellite developed by ICEYE as as follows:

  • Predicted orbits: 500 m precision (image planning, emergency services)
  • Rapid orbits: 3 m precision (standard delivery along with the product)
