  • FAA approves 9 new LAANC service providers

    FAA approves 9 new LAANC service providers

    FAA also warns about drones interfering with public safety.

    The Federal Aviation Administration (FAA) has announced nine new partners to its Low Altitude Authorization and Notification Capability (LAANC) initiative, a collaboration between the FAA and the drone industry that provides near real-time processing of airspace authorizations for Part 107 drone operators nationwide who fly in controlled airspace.

    Following the FAA’s successful prototype, the initiative was simultaneously opened to additional air traffic control facilities and to new industry partners. The five-month onboarding process that began in April resulted in nine new LAANC partners — Aeronyde, Airbus, AiRXOS, Altitude Angel, Converge, DJI, KittyHawk, UASidekick and Unifly.

    The nine join five companies — AirMap, Harris Corp., Project Wing, Skyward and Thales Group — that have already met the technical and legal requirements to provide LAANC Services.

    LAANC uses airspace data, including UAS facility maps, which shows the maximum altitude around airports where the FAA may authorize operations under Part 107 in controlled airspace. The program gives drone operators the ability to interact with industry developed applications and obtain near real-time authorization from the FAA.

    LAANC, a foundation for developing the Unmanned Aircraft Systems Traffic Management System (UTM), is now available at nearly 300 FAA air traffic facilities across the country, covering approximately 500 airports.

    The FAA next year will accept applications from parties interested in becoming LAANC service providers from Jan. 7 to Feb. 8 and from July 8 to Aug. 9. This is not a standard government acquisition; there is no Screening Information Request (SIR) or Request for Proposal (RFP) related to this effort.

    Interested parties can find information on the application process here.

    FAA targets UAS violators for enforcement

    In a different announcement, the FAA said that drone pilots who interfere with fighting wildfires, law enforcement efforts, or other first responders such as medical flights  now are more likely to face serious civil penalties, even for first-time offenses.

    Deterring interference with first responders is critical as drone use expands exponentially. Firefighting aircraft trying to contain a wildfire have to suspend flights when a drone enters the area to avoid a possible mid-air collision. A drone flying over a crime scene or accident site can hamper police or medical aircraft operations.

    Ultimately, interference by a drone can cost lives.

    The FAA has provided guidance for agency personnel who handle possible drone violations to refer all cases involving interference with first responders to the FAA Chief Counsel’s office for possible enforcement action.

    In July 2016, Congress authorized the FAA to impose a civil penalty of not more than $20,000 for anyone who operates a drone and deliberately or recklessly interferes with wildfire suppression, law enforcement, or emergency response efforts.

    Under FAA guidance, inspectors generally use non-enforcement methods, including education, for correcting unintentional violations that arise from factors such as flawed systems, simple mistakes, or lack of understanding.

    However, given the potential for direct and immediate interference with potentially life-saving operations where minutes matter, offenders will immediately be considered for enforcement actions. Enforcement actions can include revocation or suspension of a pilot certificate, and up to a $20,000 civil penalty per violation.

    Location content provider Nearmap has partnered with the City of Durham, North Carolina, Public Works Department to upgrade its imagery on numerous projects.

    Using real-time imagery from Nearmap in the field, the department streamlines data collection and saves time and money.

    The department manages all infrastructure data for the city, including mapping the impervious area (structures that resist water infiltration) for the city’s $16 million a year Stormwater Utility Fee fund. “That is half a billion square feet of impervious area that we manage through digitization and review daily,” said Edward Cherry, city GIS administrator.

    After using several satellite imagery systems with low resolution and infrequent captures, Cherry and his 14-member GIS staff determined the city needed far superior quality in their mapping imagery to accommodate the city’s explosive growth.

    Captured every six months at a 2.8-inch ground sample distance, Nearmap now supplies Durham with up-to-date images accessible through web-based cloud servers.

    With Nearmap, the Durham Public Works Department has achieved better monitoring of pavement conditions; time savings and documentation of road repairs; more detailed maps of city riparian zones; and accurate and detailed customer billing.

    “With Nearmap, we’ve been able to update development processes and policies to support the revitalization of the downtown district as well as rapid city growth,” Cherry said.

  • SAE International issues new eLoran standards documents

    SAE International’s PNT Committee, a standards development working group within the Systems Management Council (SMC), has issued three new documents.

    The documents provide technical descriptions of the signal-in-space eLoran waveform and two accepted data channel techniques that include explanations and recommended practices.

    • SAE9990 − Transmitted Enhanced Loran (eLoran) Signal Standard. This transmitted eLoran signal standard provides technical descriptions of the waveform, specifications, and explanations. The data channel, receiver specification, and recommended practices are described in the SAE9990 family of standards.
    • SAE9990/1 − Tri-State Pulse Modulation Data Channel Modulation Techniques. This eLoran transmitted signal standard provides technical descriptions of a data channel based on the tri-state pulse position modulation technique. The eLoran transmitted signal standard, to which this data channel technique applies, is part of the SAE9990 family of standards covering data channels, receiver specifications, and recommended practices for eLoran.
    • SAE9990/2 − 9th Pulse Modulation Data Channel Modulation Techniques. This eLoran transmitted signal standard provides technical descriptions of the data channel using ninth pulse modulation techniques. The eLoran transmitted signal standard, to which this data channel technique applies, is part of the SAE9990 family of standards covering data channels, receiver specifications, and recommended practices for eLoran.

    The standards demonstrate the PNT Committee’s far-reaching vision and purpose of safeguarding the operations of the global economy and critical infrastructure from being overly dependent on single-source PNT services, SAE said.

    Noting that there is a growing consensus supporting the development of independent, complimentary, multi-domain PNT services that can interoperate with GPS and other GNSS, SAE is leading the charge to issue standards for eLoran.

    These three documents, when combined with future SAE PNT Committee work products, will define architectures, sensors, interfaces, training and certification recommended practices, so that the commercial marketplace can continue to develop products and capabilities to provide robust and resilient PNT solutions for consumers.

    In a field that is already experiencing unprecedented growth, these standards will promote the development of new PNT innovations, while also ensuring safe, secure and reliable operations for all modes of transport and other applications that exist on a foundation of accurate, reliable and trusted PNT capabilities, SAE said.

    As the PNT Committee is comprised of technical subject matter experts from private sector companies, consulting firms, government departments and others across the aerospace and defense industries, collaborative efforts result in mandated processes that empower users and enhance performance.

  • City emergency support improved with Nearmap imagery

    Nearmap aerial imagery in ArcMap. (Screenshot: Nearmap)
    Nearmap aerial imagery in ArcMap. (Screenshot: Nearmap)

    The Shelby County, Tennessee, Emergency Communications District has implemented Nearmap high-resolution aerial imagery to geocode and plot new addresses and developments into its 911 mapping systems.

    The mapping systems help fire and rescue, emergency medical services and law enforcement get instant access to updated maps needed to get to the right locations as soon as possible.

    The Emergency Communications District is responsible for establishing local emergency telephone service, providing the network call-handling equipment, and updating the geographic information systems (GIS) data for each Public Safety Answering Point within Shelby County.

    Nearmap provides frequently updated, high-quality aerial captures to ensure that the district’s GIS data, geocoding and the 911 mapping systems are up to date, providing public safety and law enforcement the most accurate information, the company said.

    Benefits of Nearmap aerial imagery for the Emergency Communications District include:

      • The imagery is delivered through the cloud as a subscription service, making it accessible to all team members via mobile and desktop.
      • Nearmap imagery is taken at least twice a year, both leaf-on and leaf-off to provide different views of locations in different seasons.
      • Aerial captures integrate directly into Esri ArcMap, ArcPro and ArcGIS Online applications, so GIS information can overlay directly onto the high-resolution imagery.

    Before Nearmap, Shelby County’s aerial image process required a contracted flight to photograph the county areas. Because of the high cost of capturing those images, the county purchased images once every two years, after pooling resources from various county entities.

    “With our old aerial imagery provider, there were issues with mosaicking separate images together, and since the imagery was taken every two years, many rural and unincorporated areas were out of date,” said Timothy Zimmer, GIS administrator for Shelby County’s Emergency Communications District.

    With out of date images, the county had to develop alternate methods to locate addresses for the 911 systems. Now, the combined impact of data services, base maps, Nearmap imagery and third-party data are improving all aspects of public safety, including law enforcement, fire and emergency medical services, Nearmap said. Even other agencies are using the district’s imagery and GIS data.

    “There’s a certain context and currency you can get from Nearmap imagery that you simply can’t get from any other imagery products,” Zimmer said. “Other agencies, such as the County Clerk and the Utility Company, are using our addressing data because Nearmap has helped enable us to be much more current.”
