Satellites

relative spectral response (RSR)

Aerospace; Satellites

The relative spectral transmittance as a function of wavelength. Relative spectral response (RSR) measurements are assumed to be constant for all detectors covered by a common filter and are ...

spectral response

Aerospace; Satellites

The response of a material as a function of wavelength to incident electromagnetic energy, particularly in terms of the measurable energy reflected from and emitted by the material.

temporal resolution

Aerospace; Satellites

the revisit time of a satellite over a given geographic location. The revisit time for Landsat 4, 5, and 7 is 16 days. For Landsat 1, 2, and 3 it was 18 days.

roll

Aerospace; Satellites

The rotation of a spacecraft about its longitudinal axis (in the along-track direction) so as to cause a side-up or side-down attitude. The roll axis is referred to as the "y" axis. See attitude.

The rotation of a spacecraft about its vertical axis so as to cause the spacecraft's longitudinal axis to deviate left or right from the direction of flight. The yaw axis is referred to as the "Z" ...

pitch

Aerospace; Satellites

The rotation of a spacecraft about the horizontal axis normal to its longitudinal axis (in the along-track direction) so as to cause a nose-up or nose-down, attitude. The pitch axis is referred to as ...

telemetry

Aerospace; Satellites

The science of measuring a quantity or quantities, transmitting the measured value to a distant station, and there interpreting, indicating, or recording the quantities measured. A telemetry link, ...
