This new antenna networks UAVs to expand battlefield comms
By: Maddy Longwell Persistent Systems, a New York City-based global communications technology company, has introduced a portable antenna system to incorporate unmanned aerial vehicles into a networked battlefield. The auto-tracking antenna system is an easily collapsible ground-to-air antenna that operates on the Wave Relay mobile ad hoc network (MANET), which Persistent Systems manufactures, a news release said. Persistent Systems hopes the antenna could be used in Special Operations Command's Mid-Endurance Unmanned Aircraft Systems III program. The 5-foot parabolic dish is designed to be deployed within 15 minutes and can track and rotate to follow MANET-connected technology in the air, expanding the network bubble. Persistent Systems predicts this will reduce costs by decreasing dependence on satellite communications. “The antenna helps connect far-flung forces, acting like a cheaper, locally controlled low-Earth satellite with a greater data rate,” Erik Schechter, a Persistent Systems spokesperson, said in an email. The IP67-rated antenna system, designed for any weather environment, has interchangeable S-Band, L-Band and C-Band MIMO feeds and supports high data rates, video and voice communications up to 130 miles, yet can be stored compactly and fit into a standard-sized SUV, according to the Persistent Systems press release. Schechter also said that the antenna can also be used for longer-range chemical, biological, radiological, nuclear and explosives command missions, like ones in Syria. The auto-tracking antenna system is expected to improve full-motion video and sensor data transmission from drones and is automatically calibrated to reduce user error. “The idea is for the Army, Navy, [Special Operations Command] and foreign customers to use it for better communications relays,” Schechter said. SOCOM announced in May that UTC Aerospace Systems had been selected for its MEUAS III program and would provide SOCOM with flight management and imaging systems. Previously, SOCOM had selected Insitu, a company owned by Boeing and Textron Systems, to provide technology for intelligence and surveillance. https://www.c4isrnet.com/unmanned/2018/07/23/this-new-antenna-networks-uavs-to-expand-battlefield-comms/
