Also known as Orbview-2, the SeaStar satellite carries one imaging sensor: SeaWiFS. SeaWiFS consists of eight, narrow channels selected for ocean observation, so the channels are primarily in the blue and green regions of the spectrum, with longer wavelength channels for atmospheric correction of the data. The satellite has a polar, circular, sun-synchronous 705-km orbit, and is pointable in the along-track direction to +20, 0 -20 degrees to avoid sun glint from the sea surface.

| 3 | 480-500 (cyan) | 1.13 |
| 4 | 500-520 (green) | 1.13 |
| 5 | 545-565 (green) | 1.13 |
