Sun Direction Sensor

In addition to spacecraft sun sensors find use in ground based weather stations and sun tracking systems and aerial vehicles including balloons and uavs.

Sun direction sensor. A sun sensor is a device that senses the direction to the sun. A sun sensor is a device that senses the direction to the sun to measure the position of the sun or other light sources with respect to the sensor position. To test motor 1 set the steps to 200 the interval to 20ms and the direction to forward. The high sensitivity reached is based on the geometrical dimensions of the design.

Analog sensor whose output signal is a continuous function of sun angle. The sensor inputs since we want to be able to track the sun we need some form of light detector. Sun sensors are used for attitude control solar array pointing gyro updating and fail safe recovery. Click on the run button and you should see motor 1 do one complete revolution in about 4 seconds.

This can be as simple as some solar cells and shades or as complex as a steerable telescope depending on mission requirements. An earth sensor is a device that senses the direction to earth. The sun tracking sensors were experimented in operative conditions with direct exposition to the sun. Field tests of the sun finder sensors.

Iss dx sun sensor measures the incident angle of a sun ray in both orthogonal axes and the solar radiation. A sun sensor is a navigational instrument used by spacecraft to detect the position of the sun. You now have. However the main advantage of pinhole sensor is to work on two axes while the slit sensor is a sun pointing system working only in one direction.
