Just a quick idea of the measurements.

1.1 Ground based measurements

1.2 Space based measurements

To take your measurements.

Some optical measurements of small debris in LEO have been done, but in general radars outperform telescopes for measurements in LEO.

The models and measurements developed are identical in many respects to the models and measurements used to understand the interplanetary meteoroid environment.

Basically two types of radars are used for space object measurements

The measurements provide the latitude dependence of ionospheric electron content (TEC).

119. In general, measurements are performed through the use of sensors.

Together with other measurements performed as part of MTPE, these data will help form the first long term integrated measurements of the Earth s land, air, water and life processes.

So, I was trying to basically make measurements.

While synoptic scale measurements are mainly derived from satellite data, ground based and airborne measurements add increased temporal and spatial resolution, and provide critical validation of satellite sensors.
