The SPIDER (Ship Position and Detection Radar) is a novel low SWaP payload, based on COTS components, tailored to support persistent and reliable maritime security and surveillance from HAPS. SPIDER is specifically designed for ship position, detection, and tracking. It is complementary to and can provide cueing to other maritime sensors. SPIDER design is compatible with deployment on Zephyr S with potential progression to a low-cost space-borne payload. This paper provides an overview of the SPIDER concept and the results of the proof of concept trials undertaken in late 2017 under joint CEOI and Airbus funding.
