Astrometric tests based on data from Event-Based Sensor camera

Joachim Krüger, Krzysztof Kamiński

Monitoring of artificial earth satellites is an important task, because the amount of active satellites and space debris is constantly growing, which increases the risk of collision, and in the long term will significantly hinder the use of the most popular orbits. Optical observations are a cheaper alternative to other expensive tracking systems based on radars or laser ranging. Due to the high temporal resolution, EBS cameras have the potential to use them in observations of artificial Earth satellites. Especially in the area of detecting and tracking satellites in low orbits. We present novel algorithms of astrometric measurements designed specifically to analyze the EBS data stream. The basic variant uses only x,y positions recorded by the camera, the advanced version is also using timing data of each individual event. The algorithm has been tested on real observational data recorded in 2018. The accuracy of position measurements has been estimated at about 1.5 arcesc when using data with a pixel scale of 7 arcsec/pix.
