**SPOT HRV pushbroom arrangement.** - Uses **thousands of CCDs (Charge-Coupled Devices)** in a linear array — many more detectors than the few that MSS/TM used. - Images a **complete cross-track line in one look**. - **PAN mode** = panchromatic line; **XS mode** = multispectral lines (one linear array per band). - A **steerable mirror (view angle 4.13°)** allows **±27° off-nadir** pointing, producing **stereo-pair** imagery and a **3–5 day revisit** at mid-latitudes.
