Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Small satellite platforms with television cameras onboard became popular in recent years. Many of these devices are non-commercial and are student-built. The small budget of such a mission suggests mainly educational use. Meanwhile, high-quality pre-flight radiometric calibration of onboard equipment will significantly expand the range of remote sensing tasks performed by the mission. This article describes a method and equipment for measuring the main energy characteristics of television cameras - signal transmission function, zone characteristics, noise signal of matrix detector. The proposed equipment provides a high dynamic range with good accuracy and has a low cost.
