ON Semi is proud to report the good performance of its sensors used in NASA Perseverance mission:

"The Perseverance mission has a total of 23 cameras, 19 of them are mounted on the rover itself and 16 of those are intended to be used by the rover while it is on the surface. The remaining seven cameras, both on the rover and the entry vehicle, were there largely to support the EDL phase [Entry, Descent, Landing process] of the journey. Of those seven cameras, ON Semiconductor supplied the image sensors for six of them.

Three of the cameras, designated Parachute Uplook Cameras (PUC), were used purely to observe the parachute as it opened on the descent. Two of the other cameras, designated Rover Uplook Camera (RUC) and Rover Downlook Camera (RDC), provided similar insights and operated at 30 fps for the whole of the EDL period.

The sensors used in the PUC, RUC and RDC are the PYTHON1300, a 1.3 megapixel, ½ in CMOS image sensor with 1280 by 1024 pixels. Together, all three cameras captured over 27,000 images during the ‘seven minutes of terror’.

The sixth ON Semiconductor image sensor now residing on Mars is a PYTHON5000, a 5.3 megapixel image sensor with a 1 inch area and pixel array of 2592 by 2048 pixels. This sensor is used in the Lander Vision System and is referred to as the LCAM. This camera has a field of view of 90° by 90° and provides the input to the onboard map localization Terrain-Relative Navigation system."

The PYTHON series of industrial vision sensors has been designed in the company's design centers in Mechelen, Belgium and in Bangalore, India.
