“Coast Guard RDC evaluates Beyond Visual Line of Sight technology for UAS” –CG-9

V-Bat from Martin UAV

The Acquisitions Directorate has a post, duplicated below, reporting on evaluation of a “Detect and Avoid” (DAA) system mounted on a small unmanned air system (sUAS). To me, the most significant part of the report is at the end,

“What’s on the horizon? Future evaluations will be focused on two capabilities:

  • “Investigating DAA technologies incorporated onboard a long endurance UAS capable of operating for 6.5 hours. This effort will support future UAS operations with Coast Guard vessels not equipped with a flight deck. (emphasis applied–Chuck)
  • “Evaluating vertical takeoff and landing UAS equipped with DAA technologies for operating onboard cutters with a flight deck.”

Operating UAS from non-flight deck equipped cutters is good news. (WPCs, WPBs, and maybe buoy tenders? Apparently they are operating from a 45 foot Response Boat-Medium.) The specificity of the “6.5 hours” operating capability must mean they are looking at a particular system.

The Coast Guard Research and Development Center (RDC) is evaluating Detect and Avoid (DAA) technologies to enable unmanned aircraft systems (UAS) to operate Beyond Visual Line of Sight (BVLOS) without relying on Coast Guard cutter systems for clearing airspace.

Current Federal Aviation Administration (FAA) rules prohibit UAS in national airspace under visual flight rules because UAS cannot detect and avoid other aircraft. DAA technologies may provide one solution to meet national airspace requirements, allowing the Coast Guard to expand its use of UAS to maintain better awareness of activities in the maritime domain.

“The ultimate goal of this project is to provide a pathway for UAS to operate BVLOS for both flight deck-equipped cutters and smaller vessels without a flight deck, providing a tool to increase mission effectiveness for Coast Guard surface operations,” said Steve Dunn, a researcher with the RDC Aviation Branch who is leading this effort.

In addition to supporting operation of UAS to cover greater distances at sea and patrol operational areas from land-based stations, DAA/BVLOS technology could increase Coast Guard efficiency by eliminating the need for a dedicated air direction controller to keep UAS clear of other aircraft.

Acoustic signature system

The RDC evaluated a DAA acoustic signature system called Passive Acoustic Non Cooperative Aircraft Collision Avoidance System (PANCAS) in August 2020 at Air Station Cape Cod, Massachusetts. The objective was to capture audible range data on how far the UAS could detect other aircraft to support future commands for UAS operators to avoid other airborne targets.

The PANCAS technology uses sound rather than radar and computer vision to detect things in its airspace. It has the potential to be used by UAS operators located on cutters or at land-based units, covering the full range of UAS operations.

PANCAS looks for an acoustic signature to identify aircraft in its vicinity and alert the UAS operator, who can then take evasive action to avoid the other aircraft. This equipment is also an example of a passive technology, meaning it is constantly listening for an acoustic signature and has 360 degree listening range. This technology may prove to be an alternative to active transmitters, which may not have 360 field of view and possibly require a lot of power from the UAS’s limited power supply.

The PANCAS evaluation was very successful; however, the technology is not at the stage where it can be submitted to the FAA for approvals. Additional engineering will be done to integrate waterproof microphones into the UAS wing, enabling the system to land in the water.

Long-range directional antenna

The RDC utilized a Cooperative Research and Development Agreement in November 2020 to evaluate a long-range directional antenna developed to extend the operational range of an AeroVironment Puma UAS. With the antenna, the RDC was able to successfully operate the Puma out to a range of 31 nautical miles. For this evaluation, the RDC team established two ground control stations — one land-based unit at Air Station Cape Cod and one onboard a response boat from Coast Guard Station Cape Cod Canal.

The evaluation was successful and proved the antenna’s viability for ground-based operations; data gathered will help support future BVLOS operations using DAA technologies. The demonstration also validated the need for a 360-degree directional antenna for BVLOS operations by the Coast Guard boating community. The RDC team is investigating further partnerships involving directional antennas to provide that capability.

The ability to operate smaller UAS such as a Puma farther away from Coast Guard vessels may unlock the full potential of UAS, providing a force multiplier for non-flight deck equipped cutters. Extending the range and flight time of smaller UAS are key factors for operating BVLOS.

What’s on the horizon?

Future evaluations will be focused on two capabilities:

  • Investigating DAA technologies incorporated onboard a long endurance UAS capable of operating for 6.5 hours. This effort will support future UAS operations with Coast Guard vessels not equipped with a flight deck.
  • Evaluating vertical takeoff and landing UAS equipped with DAA technologies for operating onboard cutters with a flight deck.

The goal of both efforts is to obtain an FAA Certificate of Authorization to use DAA technologies for operating BVLOS. The RDC plans to continue evaluations through early 2023; however, schedules may be impacted by COVID-related travel restrictions.

“New Drone Surveillance System to be Deployed on Canadian Coast Guard Vessels in Trials Funded by DRDC” –Kongsberg Geospatial

Image credit: Kongsberg Geospatial

Below is a news release from .Kongsberg Geospatial. It talks about a demonstration of their sensor data management system, called MIDAS, to be conducted with the Canadian Coast Guard, in conjunction with the Martin UAV V-BAT fixed-wing vertical take-off and landing (VTOL) Unmanned Aerial System (UAS).

What really got my attention is that their illustration, above, appears to indicate that they expect to operate the V-BAT from Hero Class Cutters. These cutters are closely related to the USCG Webber class, but are smaller, 14 feet shorter and over three feet narrower. If they do succeed in operating it off the Hero Class, then we should also be able to operate it off the Webber class cutters.

We have talked about V-BAT before, and in fact, it was operated for a short evaluation from USCGC Harriet Lane. You can read about V-BAT here and here.

Sounds like a very interesting demonstration. Perhaps CG R&D could send an observer.


New Drone Surveillance System to be Deployed on Canadian Coast Guard Vessels in Trials Funded by DRDC

Ottawa, CA: Kongsberg Geospatial announced today that it has been selected by Defence Research and Development Canada (DRDC) to conduct trials of a new long-endurance UAV surveillance system for the Canadian Coast Guard. The Martin UAV V-BAT aircraft was selected to provide the unique ability to combine take off and landing from the small confines aboard ship with the long endurance of a fixed-wing aircraft while carrying multiple sensors.

Combining a unique Vertical Take-off aircraft and new sensor data PED solution allows for rapid collection and analysis of sensor data

The aircraft will communicate with the Kongsberg Geospatial sensor data management system, called MIDAS, which allows a range of sensor data, including full-motion video from unmanned systems to be processed and exploited in near real-time by analysts on board Canadian Coast Guard ships. MIDAS provides the capability to compare historical and live data from the mission area, and to examine sensor data with a variety of tools, including motion and object detection, in near-real time. This near real-time analytical capability can greatly enhance the effectiveness of UAVs for a variety of mission types.

The V-BAT Unmanned Aerial System (UAS) provided by Martin UAV is a fixed-wing vertical take-off and landing (VTOL) aircraft specifically designed to operate from very small spaces on ships, land, and nearly any environment. The V-BAT is a long-endurance aircraft capable of carrying multiple sensors, including land and maritime wide area surveillance.

Kongsberg Geospatial’s MIDAS is derived from technologies created for the NATO Alliance Ground Surveillance project which required the storage and retrieval of vast amounts of intelligence data for Intelligence Analysts. The system directly addresses the problem that the vast majority of UAVs have no standards-compliant capability to process, exploit, and distribute (PED) their sensor data where it is being used. MIDAS provides a fully standards-compliant system that allows intelligence analysts to view, process, and analyze sensor data in near real-time, from where the drone is being operated. MIDAS has packaged these capabilities into a tactical and portable form factor to enables those surveillance capabilities to be deployed as a portable system on board a ship, or in a temporary command post.

CINTIQS Military Technology Consulting will be providing consulting services for the planning and conduct of the flight trials and sensor employment to validate systems performance.

The combination of the Martin UAV V-BAT and the Kongsberg MIDAS sensor data management system will allow Coast Guard vessels to significantly expand their surveillance range for search and rescue missions, and for the surveillance of the movement of icebergs, without requiring the use of manned aircraft.

“UAVs are a useful tool, but they only truly effective if they can collect sensor data that results in actionable intelligence”, said Ranald McGillis, President of Kongsberg Geospatial. “Our MIDAS system allows users to fully exploit raw sensor data, and derive useful intelligence at the tactical edge where the UAV is being used. In a search and rescue context, that could mean using infrared sensors, or near real-time motion detection to locate a subject when visibility or weather conditions are poor.”

Martin V-BAT “Guard evaluates new technology for unmanned aircraft system operations” –Acquisitions Directorate (CG-9)

Below I have reproduced a story from the CG-9 Website. To put this into perspective the V-Bat system has a slightly smaller wing span than the ScanEagle (9′ vs 10’3″) and weighs about twice as much (88 lbs (40 kg) vs 44-48.5 lb. (22 kg)), heavier, but still easily handled. There is a skid under the nose to allows the V-BAT to be laid on the deck. Cruise speeds are similar. Dash speed is actually a little higher for the V-BAT (90 vs 80 knots). V-BAT has “Wind Limitations: 20 kt + 5 kt gust spread” for takeoff that should be relatively easy to achieve by adjusting course and speed to minimize wind over deck, but it might be a factor if we want to launch during a chase. V-BAT has a 182cc 15 HP 2-cylinder EFI engine which can use either a Gas-Oil Mix or JP-4/5/8. It has a remote start and can provide 500 watts onboard electrical power. It has a 350 mile range (statute miles I presume, so about 300 nautical miles) and has a highly accurate fuel monitoring system

Interestingly, for operation from say a Webber Class FRC, there is also a smaller electric eV-BAT.

  • Wing Span: 5 ft
  • Length: 4 ft
  • Weight: 18 lbs
  • Ceiling: 5k ft
  • Speed: 50 kts
  • Propulsion: 3 HP electric motor

The electric eV-BAT is probably both very reliable and very quiet. I am guessing, based on what I know the technology it has an endurance of about 20 minutes. Its sensors would be limited by the lower payload weight.

Don’t believe any of these smaller UAVs have a “sense and avoid” system to prevent mid-airs so they, and the surrounding air space, has to be monitored while they are airborne.

The Coast Guard Research and Development Center (RDC), Coast Guard Atlantic Area and U.S. Southern Command (USSOUTHCOM) conducted a collaborative unmanned aircraft system (UAS) pilot program utilizing a vertical takeoff and landing (VTOL) UAS Aug. 13-14. The pilot program utilized contractor-owned, contractor-operated UAS services on-board Coast Guard Cutter Harriet Lane in the USSOUTHCOM area of responsibility for a short-term deployment.

“SOUTHCOM has long had interest in the demonstration of this technology, and we are always looking for opportunities to advance our knowledge of its capabilities,” said Cameron Stanley, command science adviser for USSOUTHCOM. “This was a great opportunity to evaluate the potential use of this technology alongside our critical interagency partners to advance the state of practice and enable our collective response to common operational challenges.”

The Martin UAV V-BAT was used for this program; it is the first-ever VTOL medium range UAS to be evaluated during an operational Coast Guard patrol. Because of the vertical takeoff, a VTOL UAS does not require any additional gear on the flight deck to support operations, unlike other UAS that require launch and recovery devices.

The deployment is providing the RDC invaluable data for supporting future VTOL medium range UAS capabilities and efforts involving Beyond Visual Line of Sight operations. While the evaluation is looking at how successfully VTOL systems take off and land on board a Coast Guard cutter, patrol data can be used to refine the concept of operations and requirements for installing and integrating VTOL UAS across current and future cutter classes.

UAS technology has already proven to be a game changer for the Coast Guard. Information provided by sensors aboard UAS “impacts timelines for obtaining a statement of no objection for boarding vessels, provides situational awareness for boarding crews prior to embarking on targets of interest and provides a better covert means for tracking targets of interest,” resulting in enhanced maritime domain awareness and mission execution, explained Stephen Dunn, RDC aviation research scientist. “The VTOL system takes things a step further by reducing the footprint of the UAS for future Coast Guard cutter acquisitions,” Dunn said.
