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.

L3Harris to build prototype satellite capable of tracking hypersonic weapons
Nathan Strout WASHINGTON — The Missile Defense Agency awarded L3Harris Technologies a $121 million contract to build a prototype satellite capable of tracking hypersonic weapons, the agency announced Jan. 14. Under the contract, L3Harris is tasked with building an on-orbit prototype demonstration for the agency's Hypersonic and Ballistic Tracking Space Sensor, a proliferated constellation in low Earth orbit that is capable of detecting and tracking hypersonic weapons. The constellation is designed to fill the gap in the country's missile defense architecture created by hypersonic weapons, which are dimmer than traditional ballistic missiles, making them harder to see with the nation's infrared sensors based in geosynchronous orbit. In addition, they are able to maneuver around terrestrial sensors. With China and Russia developing these weapons, the Department of Defense is eager to develop a new constellation that can detect and track the threats anywhere in the world. And so is Congress — in December lawmakers set aside $130 million to fund the project. The HBTSS design solves the hypersonic weapon problem by placing the sensor much closer to the Earth's surface in the lower orbit, making it easier to see the threat. But because the sensors are closer to the Earth, they have a far more limited field of view than the sensors in geosynchronous orbit. In order to achieve global coverage, the Missile Defense Agency wants a proliferated constellation made up of dozens of satellites on orbit. L3Harris was one of four companies awarded $20 million contracts in 2019 to develop a prototype payload design and risk reduction demonstration for HBTSS, along with Northrop Grumman, Leidos and Raytheon Technologies. According to the initial contract announcements, work on those designs was due Oct. 31, 2020. With this most recent award, L3Harris has won the subsequent competition between the four companies to build the actual prototype. The company has also been selected to build satellites for the Space Development Agency that will track hypersonic threats and feed data to HBTSS. In October, L3Harris won a $193 million contract to build four of the agency's eight wide field of view (WFOV) satellites, with SpaceX building four more. According to Space Development Agency leaders, their satellites will work in conjunction with HBTSS satellites to track hypersonic threats. The WFOV satellites will provide initial detection and tracing of the weapons, passing custody from satellite to satellite as the threats traverse the globe. Then, the WFOV satellites will pass custody to the medium field of view HBTSS satellites, which can provide targeting solutions with their more accurate sensors. The WFOV satellites are scheduled for launch as early as September 2022. Work on the HBTSS prototype contract will be complete in July 2023. https://www.c4isrnet.com/battlefield-tech/space/2021/01/14/l3harris-to-build-prototype-satellite-capable-of-tracking-hypersonic-weapons/
