Save space inside your nanosatellite

Eagle Plus can fit between the solar panels. By mounting these sensors in underutilized areas such as between the solar panels, you not only enhance the efficiency of your satellite but also save valuable space for additional payloads.

CubeSat sun sensor Eagle Plus in a clean room.

Sun sensor Eagle Plus operates independently of the onboard computer. All calculations are performed by the built-in microcontroller, giving you calibrated information about the position angles in two axes. You can then define parameters and corrections for measuring and processing data over time.

Eagle Plus is supplied in a fully space-qualified state, having undergone all essential environmental tests necessary for technologies ready for space flight.

Sample, Hold & Read

The SHR feature enables instant sun position "snapshots" from all utilized Eagle Plus sun sensors in one command. This highly requested function facilitates efficient data retrieval, enhancing the sensor's overall utility and versatility.
