This paper describes a broadband wireless network based on aerial platforms to deliver broadband internet throughout the Columbia River skyway. It requires NO terrestial towers.
Sprint’s HAPSMobile has established an innovative wireless platform, now being tested in Hawaii. It uses a solar-powered ultralight drone orbiting at 12 miles. Sprint’s high altitude broadband platform enables ordinary 4G/5G broadband service everywhere in its footprint. It also enables innovative, cost/effective new tools for governments and private agencies including low altitude UAVs and autonomous marine vessels.
– The goal is to provide persistent vision, day and night, for all marine vessels on the Columbia River and enable the development of autonomous boats and Beyond Visual Line of Sight surveillance drones.
– A secondary goal is to provide BLANKET IoT services and consumer broadband ALL along the Columbia River, from Umatilla to Astoria.
– Emergency broadband communications is an additional motivation.
LEO satellites, like those planned by OneWeb and SpaceX, CANNOT link directly to phones. LEO satellites require large antennas. The HAPSMoble UAV platform can. It’s a cell tower. It enables small autonomous water vessels, Beyond Line of Site UAVs, autonomous vehicles, and a multitude of IoT devices. Standard 4G/5G service all along the Columbia River.
NOTE: This paper is an informational overview. Whether high-altitude broadband platforms would be useful and cost/effective for Oregon and Washington stakeholders is beyond the scope of this paper.
12 MILE HIGH CELL TOWER
The Columbia River broadband communications cloud might enable a new era of cost/effective river patrol and transportation, enabling autonomous marine vessels, among other things.
Sprint’s HAPSMobile, using an AeroVironment HAWK30 solar-powered platform, is essentially a cell tower in the sky, 12 miles (20km) high. It delivers cellular service over a 200km (125 mile) diameter area.
One HAWK50 orbiting over Longview could cover Astoria to Portland and would be based at the UAS facility in Tillamook. A second HAWK50, orbiting over The Dalles (60 miles up river) would cover Portland to Umatilla region and would be based at the UAS facility in Pendleton.
The high altitude Sprint/Aerovironment platform (pdf) is positioned at 65,000 feet, delivering cellular service at 1.9 GHz and 2.5 GHz. The Sprint platform is currently being tested at the Pan Pacific UAS Test Range. The solar-powered platforms remain in orbit for months at a time and can deliver seamless broadband coverage, unlike terrestrial towers.
Facebook joined the SoftBank/Sprint program as part of a collaboration between the two companies. Facebook will utilize the 26GHz and 38GHz spectrum (mostly for tower backhaul), but Sprint will use their 2.5 GHz cellular spectrum for direct phone connections. HAPSMobile also has a strategic relationship with Loon, a subsidiary of Alphabet.
Sprint/Softbank hopes to start commercial service in 2023. However, a different drone, the HAWK50, would be required for service at higher longitudes, between 30-50 degrees, where we are located.
OREGON’S DRONE RANGES
The States of Oregon and Hawaii are original partners with Alaska in the Pan-Pacific UAS Test Range Complex (PPUTRC).
Oregon has the ONLY west coast drone test bed in the United States and it includes three different UAS test ranges:
(1) The Pendleton Unmanned Aerial Systems Range, managed by the Alaska-based Pan-Pacific UAS Test Range. The Pendleton airport provides a dedicated 2,800-foot UAS airstrip and a full-service UAS operating area extends over 14,000 square miles: North to the Columbia River; east over the Blue Mountains and Umatilla National Forest. A large UAS industrial park north of the Pendleton airport’s runways is being constructed.
(2) The Tillamook UAS Test Range, managed by NearSpace, Inc. Near Space Corporation has over 20 years of experience conducting flight tests of space and unmanned technologies within the National Airspace System, and operates both the Johnson Near Space Center and the Tillamook UAS Test Range.
PENDLETON DRONE RANGE
Current customers of the Pendleton Unmanned Aerial Systems Range include Airbus, which is testing their autonomous air taxi Vahana, defense contractor PAE ISR with their Resolute Eagle, Pacific Northwest National Laboratory flying their Artic Shark, San Diego-based defense and transportation contractor Cubic Corp with Command and Control products on wildfire drones, and Yamaha’s remotely guided crop-dusting helicopter, the RMAX.
Oregon State University, a longtime partner of UAF on research activities, is also part of the Oregon test site team. Boeing’s Insitu, the drone pioneer based near Hood River, has been flying their Scan Eagle and RQ-21 Blackjack around the Gorge and eastern Oregon for nearly a decade.
The city of Pendleton is expected to receive a $3 million federal grant for the range’s final phase, a large UAS industrial park north of the Pendleton airport’s runways. This will attract more high profile UAS business to the region.
Non-line of sight developments may expand the range and impact into protected airspace such as the Columbia River Corridor.
Operations in Hawaii are quickly developing, including a UAS test facility on Lanai (where Sprint is testing its’ HAPs Mobile platform). As with OSU, the University of Hawaii has a long-standing academic partnership with Hawaii’s UAS test facility.
DRONE OPERATIONS IN NATIONAL AIRSPACE
One of the main goals of drone testing at the Pendleton Airport is to test the integration of drones into the National Airspace System (NAS).
The Air National Guard at the Pendleton Airport currently flies the Group 3 RQ-7 Shadow drone. The DOD plans to replace this model with something similar to the PAE Resolute Eagle, also being tested in Pendleton.
The PAE Resolution Eagle doesn’t need a catapult, like the RQ-7 Shadow. PAE expects to conduct operations in the National Airspace in 2020, integrated with civilian aircraft.
AUTONOMOUS MARINE VESSELS
Oregon Iron Works has delivered multiple unmanned surface vessels and is often responsible for concept through the detail design.
The Vigor/Oregon Iron Works Mine Countermeasures Unmanned Surface Vehicle (MCM USV) is a long endurance, semi-autonomous, diesel-powered, all-aluminum surface craft that supports various MCM payloads. Oregon Iron Works is developing autonomous seaplanes for EO/ISR and communications relay missions like the Sea Scout air vehicle.
Bluefin Robotics uses low-bandwidth communications, with Iridium for remote connections, radio for local links and acoustic communications underwater.
Enabling drones to fly in controlled airspace may be the next frontier. ADS–B boxes use GPS to determine an airplane’s position, broadcasting it to other aircraft. ADS-B will be mandated for all aircraft starting in 2020 and is available in the size of a business card today. A 12 mile high cell tower can also relay video from low altitude drones – well beyond line of sight – for improved situational awareness.
Currently, collision avoidance for drones requires a number of terrestrial radars along the drone track. Echodyne radar on UAVs can detect and avoid other aircraft while in flight while Echodyne ground-based radars scan the skies for aircraft entering their operating area.
The University of Alaska’s Unmanned Aircraft Program conducted the first ever beyond-visual-line-of-sight (BVLOS) drone operation. It was powered by Iris Automation’s on-board system and Echodyne’s ground-based, detect-and-avoid system integrated onto a small Skyfront Perimeter UAV.
BEYOND LINE OF SIGHT
Insitu has successfully demonstrated a ground-based airspace situational awareness system for drones. It detects nearby aircraft while flying, either within or beyond visual line of sight. “We’re developing our ability to fly long distances with our UASs that satisfies the airspace regulators, providing UAS operators with access to information that we previously just couldn’t obtain otherwise,” said Mark Bauman, Vice President and General Manager, Insitu Commercial.
Predator drones, in partnership with the FAA, NASA, and industry partners, are also helping to define airspace regulations for Anti-Collision Systems that will allow further integration of drones into civilian airspace.
SPY IN THE SKY
Line of sight communications links are required between drones and controllers but that limits their range. Persistent Systems uses their MPU5 Wave Relay mobile ad hoc networking (MANET). Their platform agnostic radio can operate not just from Resolute Eagle drones, but from multiple drones, ground robots, and in systems carried by people on foot. By contrast, Silvus Technologies creates a high-throughput IP network connecting situational awareness resources including drones, body-worn cameras, smart devices, and IP-enabled sensors.
LIVE FROM HERE
Wide Area Surveillance packages are being tested on Insitu’s Integrator aircraft in Eastern Oregon for 24/7 “Eye in the Sky” surveillance that may revolutionize policing – for better AND for worse.
The Redkite package consists of a 50-megapixel sensor that snaps an image every other second. It can monitor a nearly 5 by 5 square mile area from 12,000 feet. Redkite stores the collected imagery on solid state drives and also beams it to ground stations via data link such as Sprint’s HAPSMobile.
Spooked by surveillance technology? Nearly every street corner, office and store has cameras pointed at you.
Clearly, surveillance technology is controversial. Drones over the Columbia river might, at least, provide some standoff distance, as well as provide some significant safety and economic advantages.
WHAT TO DO?
Technology happens. Autonomous cars, autonomous vessels, autonomous airplanes. Broadband everywhere. Spies in the sky. Where is it going? Who knows. Let’s dip our toes in the water. Try something. Apply for some grants. Get it out there. Some applications will be useful and worthwhile. Some not. Let’s keep the conversation open.
