uAvionix ADS-B solution implemented by V-TOL for disaster management in South West Pacific

Posted by uAvionix Australia on

Cyclone Gita

Category 4 Cyclone Gita hit Tonga in February this year with winds up to 233km/h. Gita was reported as the worst cyclone to pass so close to Tonga in 60 years causing widespread and severe damage. Emergency response teams struggled to assess damage around the capital on the main Island of Tongatapu. As a result, the Brisbane based V-TOL Aerospace Disaster Response Team was deployed by the World Bank with the support of the Australian Government with their GosHawk II UAVs to survey the Tongatapu Island Group. The GosHawk UAVs were launched from the Fua’amotu International Airport to map the main island as rapidly as possible.

ADS-B mandatory for unrestricted Beyond Visual Line of Sight (BVLOS)

Automatic Dependent Surveillance – Broadcasting (ADS-B) was mandatory for the unrestricted integrated BVLOS operations during the Gita Response. The uAvionix ping20s transponder and FYXnav-B GPS ADS-B solution installed on the GosHawk facilitated real-time monitoring by Air Traffic Control (ATC) at Fua’amotu International Airport Tonga, the V-TOL team on Tonga, V-TOL HQ in Brisbane, commercial jets and Civil Aviation Authority of New Zealand. The ADS-B output was used by ATC as the primary means of separating commercial aircraft movements from the uAvionix ADS-B equipped UAVs when operating BVLOS from the tower.

2,500km of survey operations were flown 1000ft AMSL in just 5 days

At the completion of flight operations conducted by V-TOL:

  • 100% of Tongatapu was imaged (approximately 300km²)
  • 2,500km of BVLOS survey operations were flown 1000ft AMSL
  • 15km BVLOS range was reached from the V-TOL Team
  • 500GB of data was collected and processed into maps for damage assessment

uAvionix Australia firmly believe the fitment of such equipment may provide a basis for CASA to approve commercial UAV operations BVLOS and flights closer to controlled airspace. V-TOL Aerospace intends to use the Ping technology to transit all classes of airspace in 2018.

uAvionix Australia would like to thank V-TOL Aerospace for their continued support. The deployment to Tonga has enhanced the development process of uAvionix products in Australia that will enable future capabilities for all UAV operators.
