Terra Drone India undertakes digital preservation of 16th-century monument

Terra Drone India undertakes digital preservation of 16th-century monument

Hyderabad-based drone startup Terra Drone India has successfully completed a multi-sensor, multi-platform scanning of internationally recognized landmark Charminar. Built in 1591, the monument, which is often called as ‘Arc de Triomphe of the East’, suffered significant damage in May 2019 when a huge chunk of lime-plaster from its south-west minaret broke and fell off. This incident made the digital preservation of Charminar extremely time-sensitive and important for the Indian government, and the IT department of Telangana state government invited Terra Drone India to provide innovative technological solutions for the digital preservation of Charminar. 

On Thursday, Terra Drone India scanned and surveyed the damaged minaret using multiple technologies. The solution-set included:

1.       Air Gap Measurement through Ultrasonic Pulse Velocity Testing technique: The Archaeological Survey of India, the Indian government body responsible for archaeological research and the conservation and preservation of cultural monuments in the country, had expressed concern regarding the increasing air gap between the plaster and the actual facade of Charminar. Terra Drone India carried out Ultrasonic Pulse Velocity Testing, a non-destructive testing technique, to measure the air gaps that have developed in the areas of concern till date.

2.       True Color 3D Model Creation using Visual (RGB) Sensor: A high-accuracy Visual (RGB) scan was carried out to maintain a record of the facade, actual color, and any visible cracks or crevices. Through this, a true color 3D model will be created.

3.       Thermal Scanning: The scan was conducted to detect differences in temperature between different areas of the monument and identify how the different materials used in the monument are reacting to heat and how they are at risk of damage.

4.       LiDAR 3D Profiling and Model Generation using LiDAR: In order to preserve the current existing infrastructural design and layout of the monument for future rebuilding or repair works, a LiDAR survey was carried out to create a high accuracy 3D model, accurate up to the millimetric level.

Wing Commander Polu Sreedhar, Chief Operating Office, Terra Drone India, says, “Heritage monuments like Charminar are the treasures of our nation and symbolize the pride of our civilization. Terra Drone India has collated multiple technologies under one umbrella and provided it as a holistic solution to the Archaeological Survey of India to help preserve the monument that speaks volumes about our Indian heritage, culture and ancestral prominence.”

80% of drone airprox reports are misclassified by the UK Airprox Board

80% of drone airprox reports are misclassified by the UK Airprox Board

Following a Freedom of Information Act request, the UK Airprox Board, the official body which collates airprox (‘near miss’) reports from pilots, described the process they use for classifying a drone airprox:

The Board adopts a pragmatic approach wherein if a pilot can positively identify the object as a drone (e.g. number of rotors, recognition of a particular type) then the reporter’s identification is taken at face-value. If a reporter can only describe the object in generic terms (e.g. a rectangular object) then the UKAB classify it as an unknown object.

Analysis of the 216 airprox reports published in the current format using this ‘pragmatic approach’ reveals that 187 (over 80%) have been misclassified as ‘drone’. Shockingly 6 out of the 7 airproxes published in April 2019 were misclassified as ‘drone’.

Some examples:

Airprox 2018032 – ‘Drone’ The F15 pilot reports that he was on the ILS approach when both crew saw something go down the right side of the aircraft. They both thought that it was not a bird but that it could be a ‘gyrocopter’ or some type of UAS. The pilot advised the crew in an aircraft that was behind them on the approach who did not see anything.

Airprox 2018089 – ‘Drone’: The B787 pilot reports that on passing 800ft in the climb-out from Heathrow RW09R, a black object about 1-2ft wide, believed to be ‘copter’ shaped, passed 100ft down the left-hand-side of the aircraft. ATC were informed.

Airprox 2018222 – ‘Drone’: The B737 pilot reports that they were being vectored for RW22 at Stansted when the Captain called ‘drone’, at which point the FO looked up and saw a dark coloured square/rectangle shaped object pass down the right side of the aircraft with minimal separation. The airframe was inspected on the ground after landing for any evidence of suspected contact or damage and none was observed. The incident was reported to ATC immediately after making visual contact and, following confirmation, ATC confirmed they would be filing a report.

Airprox 2018275 – ‘Drone’: The A319 pilot reports that they were at 7nm final on the ILS to Heathrow RW27L, when they passed a flying object. It was V shaped, yellow and about 1m in diameter. The type of the object was not clearly identifiable, but it was thought to be a drone.

Simon Dale of Airprox Reality Check said

“Using the UK Airprox Board’s own stated ‘approach’, more than 80% of drone airproxes should in fact have been published as ‘Unknown Object’. In other words, in the last two years the UKAB’s figure is in fact forty three drone airprox reports, not two hundred and sixteen. The rest are literally UFO reports.”

The UK Airprox Board must reclassify all of their more than three hundred and fifty published drone airprox reports and notify the Minister for Aviation as soon as possible

5G!DRONES – EU H2020 Project

5G!DRONES – EU H2020 Project

5G!DRONES aim is to trial several UAV use-cases covering eMBB, URLLC, and mMTC 5G services, and to validate 5G KPIs for supporting such challenging use-cases. The project will drive the UAV verticals and 5G networks to a win-win position, on one hand by showing that 5G is able to guarantee UAV vertical KPIs, and on the other hand by demonstrating that 5G can support challenging use-cases that put pressure on network resources, such as low-latency and reliable communication, massive number of connections and high bandwidth requirements, simultaneously. 5G!DRONES will build on top of the 5G facilities provided by the ICT-17 projects and a number of support sites while identifying and developing the missing components to trial UAV use-cases.

The project will feature Network Slicing as the key component to simultaneously run the three types of UAV services on the same 5G infrastructure (including the RAN, back/fronthaul, Core), demonstrating that each UAV application runs independently and does not affect the performance of other UAV applications while covering different 5G services. While considering verticals will be the main users of 5G!DRONES, the project will build a software layer to automate the run of trials that exposes a high-level API to request the execution of a trial according to the scenario defined by the vertical, while enforcing the trial’s scenario using the API exposed by the 5G facility, as well as the 5G!DRONES enablers API deployed at the facility.

Thus, 5G!DRONES will enable abstracting all the low-level details to run the trials for a vertical and aims at validating 5G KPIs to support several UAV use-cases via trials using a 5G shared infrastructure, showing that 5G supports the performance requirements of UAVs with several simultaneous UAV applications with different characteristics (eMBB, uRLLC and mMTC). Using the obtained results, 5G!DRONES will allow the UAV association to make recommendations for further improvements on 5G.
