SUN SENSOR MARKET OVERVIEW

The global sun sensor market size is estimated at USD 0.04 Billion in 2026, set to expand to USD 0.13 Billion by 2035, growing at a CAGR of 11.4% during the forecast from 2026 to 2035.

A sun sensor is a navigational instrument used by spacecraft to detect the position of the sun. They are used for attitude control, solar array pointing, gyro updating, and reliable recovery. There are various types of sun sensors, which differ in their technology and performance characteristics. Sun presence sensors provide a binary output, indicating when the sun is within the sensor's field of view. Ana log and digital sensors in contrast indicate the angle of the sun by continuous and discrete signal outputs correspondingly. It is a device that senses direction to the sun to measure the position of the sun or other light sources with detail to sensor position.  The sensor is operated based on the entry of light into a thin split on top of a rectangular chamber whose bottom part is lined with a group of light-sensitive cells. The chamber performs an image of a thin line on the chamber bottom. The cells at the bottom measure the distance of the image from a centreline and control the refraction angle by using the chamber height. The cells are functioned based on the photoelectric effect. They convert the incoming photons into electrons and hence voltages which are in turn converted into a digital signal. They are widely used in spacecraft elevation determination systems for measuring the sun vector in spacecraft coordinates. A typical sensor operates based on the entry of light into a thin slit on top of a rectangular chamber whose bottom part is lined with a group of light-sensitive cells. Participants are fixing their efforts on encouraging R&D. Technological development are supporting the regional market growth.
