1. An optical payload (100) for directing a primary pointing axis at a target area comprising:
- a yoke assembly (105) rotatably attached to a support structure (145) and driven to rotate about an azimuth axis (A);
an optical payload assembly (110) rotatably attached to the yoke assembly (105) and driven to rotate about an elevation axis (E) wherein the optical payload assembly includes a primary video camera (310) suitable for rendering a primary video image of the target area and a secondary video camera (315) suitable for rendering a secondary video image of the target area;
an electrical control system (700) comprising a payload controller (720), housed in the optical payload assembly (110), for operating the primary and secondary video cameras (310, 315), and a master controller (760), housed in the yoke assembly (105) for correcting a primary video image of the target area, a secondary video image of the target area, a network switch (816) for receiving each of the corrected primary and secondary video images therein and a communication processor (820) in communications with a network switch (816) for merging the corrected primary and secondary images into a single network packetized data stream suitable for transmission over a radio transceiver (705) wherein data packets associated with the primary video image are addressed to a first IP address and data packets associated with the secondary video image are addressed to a second IP address.
