About

The PST3S-K4 is a micro-miniature star tracker featuring a deployment baffle, designed for high precision attitude determination on small satellites where space is at a premium. With a total folded installation footprint of just 40x40x34.6 mm3 (expanding to 40x40x75.7 mm3 with the baffle deployed) and a mass of only 60g, it is engineered for space-saving integration. It draws just 0.9W of power, uses a refractive optical lens design, and features a radiation-resistant design suitable for the space environment. It communicates via RS422/CAN interfaces, operates on a 5V input, and has a rated life time of 5 years.
