How LEO Satellites Use Sensing and Positioning Payloads for Accurate Pointing
By
Abhishek Jadhav
Summary
This article provides a technical deep dive into sensing and positioning payloads in low Earth orbit (LEO) satellites. It covers how LEO satellites estimate position, pointing direction, rotational speed, and solar array orientation. The piece explains the critical role of attitude and orbit control systems (AOCS), which integrate sensors, flight software, and control systems to maintain accurate pointing and correct orbit deviations for Earth observation, communications, and scientific missions.

· 3 pulledIn applications such as Earth observation, communications, and scientific missions, accurate pointing is the difference between usable mission data and a wasted downlink.
Attitude and orbit control systems (AOCS) in LEO satellites house the key building blocks—sensors, flight software, and control systems—that work together to correct orbit deviations and maintain.
A low Earth orbit (LEO) satellite constantly estimates its position, pointing direction, rotational speed, payload requirements, and the sun's position relative to its solar arrays.
