We work with Sprng Energy to bring the advantages of drone based hydrology solutions that climate proof their most valuable solar assets.
This is the story of how a nation that has often found itself at the back foot playing regulatory catch up with emerging technologies went from effectively banning drones or Unmanned Aerial Systems (UAS) outright to embracing them in less than 3 years by formulating a comprehensive regulatory framework that could change how drones contribute to India. This is also the story of how we like many were unable to take flight to capitalise on the 100$ billion dollar opportunity found ourselves part of a much larger story that would concern the digital evolution of the world’s fastest growing economy.
Oct 2014 - Oct 2017: Shift from regulate and forget
To understand the full scope of challenges in forming regulatory frameworks in this day and age, it helps to look at what drones mean to different stakeholders. Strangely enough, the Director General of Civil Aviation (DGCA) circular from 2014 outlines these perspectives with poignant purpose through carefully worded lines
- “However, its [UAS] use besides being a safety issue, also poses a security threat.”
Translation: “National security” is often the first word used to shoot down drones. The DGCA cited security concerns raised on behalf of ministerial heavy-weights such as the Ministry of Home Affairs. This is understandable because in a geographically diverse and geo-politically complex country like India it is exceedingly difficult to monitor things even on a ground-level.
- “The civil operation of UAS will require approval from the Air Navigation Service provider, defence, Ministry of Home Affairs, and other concerned security agencies, besides the DGCA..”
Translation: Although shared airspace is shared responsibility, someone has to take the first step towards regulatory ownership. Amidst the increased instances of illegal drones incidents and government ministries such as the Railways and Mines advocating their responsible use, the DGCA presented a set of draft regulations in April 2016 and November 2017. This represented the first framework for drones to be registered and flown, however, the regulations required interacting with multiple agencies for possibly weeks before flying. The move on drones was more of a “two steps forward one step back” approach but in the right direction.
- “…Till such regulations are issued, no non-government agency, organization, or an individual will launch a UAS in Indian Civil Airspace for any purpose whatsoever.”
Translation: The people, the startups and everyone else can either wait or facilitate regulations going forward. Through 2014, 2016 and 2017 the DGCA went from restricting to trying to formulate a way to regulate drone usage. This was significant, but to make it practical for businesses and commercial users, it was clear that the ecosystem had to facilitate a solution that had something tangible for everyone to benefit from.
Nov 2017- July 2018: Ideate, prototype and test
Amidst the flood of inputs that resulted from the November’17 draft, we were invited to a stakeholder-wide open house meet to be addressed by Jayant Sinha, Minister of State for MoCA (Ministry of Civil Aviation). The open house was both an eye-opener and a wake-up call for the nascent industry to go from being reactive and cynical to being more responsible and collaborative. The onus was to come up with a solution that accomplishes 3 cardinal requirements
- Shared airspace and drone information management
The solution should have a system that factors in inputs about airspace and security from all concerned agencies and communicates to all stakeholders about UAS operations in the country.
- Enhance and enable regulatory abilities
The solution was to enable regulatory authorities in understanding and tracing critical aspects of any given UAS operation while also enhancing their abilities and bandwidth to deal with an increased volume of aerial systems to oversee and monitor.
- Provide end users regulatory access and clarity
Whatever the system was supposed to be, it had to be user-friendly for the hobbyists, startups and enthusiasts so that they could finally understand what they need do to conduct legal operations at scale.
It was in January 2018 that we got a mail from iSPIRT, an independent think tank for Indian software products that outlined principles and ideas for a system called the “Digital Sky”. Admittedly, it started off with a hint of speculation which came from the momentum of the prevailing idea of regulations. Regardless, the principle concept behind the idea of Digital Sky led to a few players from the ecosystem to show interest in developing prototypes to understand if Digital Sky could become a reality. But, first one has to understand what the Digital Sky is and how it is intended to function
What is Digital Sky?
At a higher level, the Digital Sky is the digital bridge between the drone ecosystem and the government that satisfies the 3 cardinal requirements specified above. To meet these requirements the Digital Sky is designed to manage interactions between a drone, it’s the operator and the regulators according to 4 key design principles:
- Authenticity: A repository to store non-repudiable identities of certified pilots, drones, operating entities and operations.
- Scalability: The interactions with the system to register drones, pilots and permit/deny operations had to be as paperless, presence-less and cashless as possible.
- Security: The system above all else had to inherently ensure that no drone took off in an area and at a time when it is not supposed to be flying.
- Adaptability: The Digital Sky, had to be evolutionary in a way future applications such as BVLOS, payload delivery and, “drone ports” are but natural progressions built on the intelligence of earlier versions.
Workflows and high-level architecture for (1) and (2) were already in the works with an online registry and platform being built. Digital Sky would act as an online portal for registering certified drones and pilots. It would also act as an interface for channelling permissions to the DGCA through third-party “Digital Sky Service Providers”. This meant no more running around different government departments as the framework provided a way for regulators to trust drone users and hold people accountable. In truth (1) and (2) was soft infrastructure, something that should already be possible through the IT ecosystem in the country. However, the most crucial link in the design, i.e.,(3) security had to be an innovation on the drone itself, something unique for India’s regulatory environment, tamperproof and easily adaptable.
NPNT or No Permission — No Takeoff is essentially the security key to unlock the future for drones in India. At its core, it is a simple principle that meant drones would not be able to take-off in areas and times the Government doesn’t want them to. The rough workflow for this would be
- Pilot applies for permissions to fly using the drone’s unique ID no., intended time and area of interest of flight.
- DGCA uses the Digital Sky system to receive, verify and grant/deny permissions based on airspace state at that time and area.
- If the pilot gets the approval he/she flies the drone and maintains a record of the flight including any deviations from the intended time and area.
We volunteered to showcase a live prototype that would demonstrate parts (1) and (3) of the workflow to the DGCA and other officials.
Note: Part (2) of the workflow will be part of the Digital Sky framework which is a Flight Information Management System (incidentally only the 3rd in the world to be built after China and USA) that would create a map of the airspace in India and use inputs from all concerned parties and dynamically classify airspace . After about 2 weeks of ideating and testing, we were able to build a working NP-NT prototype. One of the key things we realised is that it’s best to enforce NP-NT protocol inside the drone and secure the firmware to ensure that this system is not bypassed.
Hence only when the drone was given a digitally signed tamper proof permission file would it take off regardless of the pilot’s intervention.
On a sunny afternoon during the month of March government officials from the DGCA and the Airport Authority of India huddled around a handful of engineers on the runway of the Mysore to understand and discuss how we implemented the system, how scalable this was for other drones in the country and what would the complications be along the way.
Skylark Drones showcasing NP-NT demos at Mysore and Delhi (March 2018 and July 2018)
The demonstration was the first step to convincing regulators that the security aspect of the Digital Sky system can be implemented in an efficient and secure way. We continued working on our implementation of the NP-NT system and proceeded to make improvements to several parts including the permission workflow. On July 1st, there was another demonstration in Rohini Heliport in New Delhi. In front of several ranked officials from various government bodies such as the DGCA, MHA and, the Indian army, Airforce and the Navy, an improved version of our Digital Sky prototype was demonstrated.
This time the officials got their first real experience of how the permission approval process would work when they were given complete control to deny or allow our drone to take-off .
A reporting mechanism for when the drone violated permission parameters was also demonstrated as an improvement beyond the Mysore trial. It was now up to the various ministries to evaluate, judge and formulate a final version of the regulations that would incorporate Digital Sky with NP-NT hopefully at the heart of it.
Aug 2018- today: Take off, collaborate and adapt
During a fairly uneventful night on August 27th, our phones began to buzz with notifications that the final iteration of the first set of drone regulations was out. Why was this so important? Because unlike the previous documents from the DGCA this did not have the word “DRAFT” watermarked across the pages, the removal of the word indicated finality, this was it. 3 years of consultations, numerous closed letters, open houses and 2 proof of concepts later we finally had a set of regulations on our hands.
Printouts in one hand, slices of pizza in the other, markers drawn and eyes focused we dove into the regulations to understand what the future would be and how our lives would change.
While the DGCA was busy addressing common questions about the country’s new laws we stayed up late, to dissect, debate and digress the entire document and understand all the little details of it. Slowly it dawned on us that not only was NP-NT mentioned about 7 times it was a requirement that would play an integral part in the final framework.
Publicise regulations, parse data, eat pizza.
As our pizzas reduced to crumbs and the excitement died down a quiet sense of collective realisation settled into the room, a realization that not only did our efforts to make NP-NT a viable concept pay off, we had also contributed to the national cause in a way that many of us may never be involved again.
Things moved in double quick time from October to December. Regulations for the entire country meant that conglomerates that had parked potential drone use cases as side projects to be showcased for “Innovation Days” moved from proof of concepts to actual plans for large-scale implementation. We had also realised that for someone from the general populace or any company that had just stumbled on to this news, they had quite a bit to catch up to understand how drones will work in India so we created an intuitive app and an explainer video to help them with what they needed to know.
As the excitement ebbed questions around technical implementation regarding, security and establishing identity were raised. So, in November, technical guidelines for drone manufacturers and operators were released which outlined all the changes to the infrastructure around drones and several security implementations in the drone itself.
Soon after the guidelines were released, iSPIRIT held a workshop for drone manufacturers to provide guidance and improve understanding on the path to compliance, and we gave the attendees a view on how we approached and implemented key principles of Digital Sky. We also announced that we are going to open-source the work we’ve done for Digital Sky in Ardupilot — an open source autopilot project for drones which has the largest user base in the world.
The workshop was the start of a much larger conversation to shape the story of drones in India. The reason behind us open sourcing our work was so that it could act as a catalyst towards other contributors within and outside the drone ecosystem to collaborate towards all aspects of making Digital Sky easier for compliance for everybody.
The long-term future for India with the Digital Sky in place would be a vibrant drone ecosystem with marketplaces for drone-based applications, on demand drone services that can aid last mile delivery and autonomous systems that monitor and maintain our pipelines, railways and power lines. Ultimately this evolution from independent opinions into one collective voice has to be integrated with a much larger movement that India is in the midst of.
The long-term future for the drone ecosystem in India relies heavily upon working with other digital platforms that are transforming the way India manages digital identities, payments and other aspects of a digital economy. In this vein, we have started working to aid the formation of DICE (Digital India Collective for Empowerment). The mission is to make sure that major digital technologies communicate with each other in a way that removes mutual roadblocks and presents all-round solutions to policies regulating technology in India that the government can act and depend on.
It is quite remarkable that in a span of 3 years we went from seeing no hope on the horizon to a place where the drone ecosystem can contribute to Digital India.
The ecosystem has started to evolve in ways that we have never thought of before, it is turning into a vibrant community of people that hopefully will set global standards towards creating an evolutionary policy mechanism that is for once on the front foot for all challenges and opportunities to come.
