Sun Direction Sensor

This can be as simple as some solar cells and shades or as complex as a steerable telescope depending on mission requirements.

Sun direction sensor.

Field tests of the sun finder sensors. A sun sensor is a navigational instrument used by spacecraft to detect the position of the sun. Sun sensors are usually classified into three types. Its characteristics make it a suitable tool for high accurate sun tracking and positioning systems with low power consumption and high reliability.

In addition to spacecraft sun sensors find use in ground based weather stations and sun tracking systems and aerial vehicles including balloons and uavs. Click on the run button and you should see motor 1 do one complete revolution in about 4 seconds. Analog sensor whose output signal is a continuous function of sun angle. 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. The sun tracking sensors were experimented in operative conditions with direct exposition to the sun. To test motor 1 set the steps to 200 the interval to 20ms and the direction to forward. Stepperbee are simple to use.

An earth sensor is a device that senses the direction to earth. A sun sensor is a device that senses the direction to the sun. The high sensitivity reached is based on the geometrical dimensions of the design. Iss dx sun sensor measures the incident angle of a sun ray in both orthogonal axes and the solar radiation.
