Summary of Inmarsat’s Pop-Up UAV Lab

Authors: Joshua Flood and David Whelan

On Thursday 30th of May 2019, we attended an Inmarsat Pop-Up UAV Lab at the firm’s Old Street headquarters.

Rupert Pearce, CEO of Inmarsat, provided an introduction to the changing dynamics and use cases for aerial unmanned aerial vehicles (UAV) and noted down several significant developments of the technology. One remarkable example is Zipline’s deployment and delivery of medicines, vaccines and blood to hospital facilities in Rwanda and other African nations.

Shortly after, Rupert announced Inmarsat’s new Aviator UAV 200, a dedicated L-band SATCOM system for UAS.

The light 1.45kg terminal capable of delivering background data services up to 200 Kbps of data, with a 1.35 seconds latency, via Inmarsat’s BGAN coverage. Its streaming class services can deliver up to 180kbps with half HDR.

The new UAV terminal will enable beyond visual line of sight (BVLOS) communications, enabling real time control of the UAV via the satcom terminal. It’s a class 4 Swiftbroadband product with Inmarsat offering hemisphere coverage to 5 degrees elevation.

Inmarsat invited several UAS entities to provide some insights into their trials and uses of the Aviator UAV 200.

These companies are listed below:

  • Silent Falcon, based in New Mexico, USA
  • A-techSYN, based in Ireland and Turkey
  • Alpha Unmanned, based in Spain
  • Robot Aviation, based in Norway
  • Flylogix, UK

Before these companies presented and participated in the panel sessions, Inmarsat’s senior UAS management program provided an introduction to its new agile management approach and developing a culture of teams workings within teams rather than its traditional siloed workings. For example, its maritime staff working on maritime projects only, aviation on aviation, government on government and so forth.

Mike Holdsworth and Andrew Legg provided some insight into how Inmarsat plans to develop specialist leaders to target certain areas for UAV solution.

These include:

  • Joe Carr – Mining
  • Steven Tompkins – Agriculture
  • Daniel Cooper – Aid/NGO/Media
  • Mike Holdsworth – Transport
  • Gary Cosby – Energy and Oil and Gas

The presentation then delved into how the Aviator UAV 200 compared to competing IoT trends, comparing an Iridium IoT terminal which weighed 30 grams, which was capable of 0.3 kbps and had a terminal latency of 22 seconds. The Aviator also performed better than Iridium’s 9522B and Aircell Axxess terminal solutions too.

Starburst, an accelerator consultancy, provided an overview of high-performance UAVs highlighting seven areas consisting of mapping and surveillance, infrastructure and energy inspection, insurance cartography, forest monitoring, ecology, search and rescue and humanitarian aid and remote delivery.

In addition, the firm illustrated performance UAVs – civil against competing solutions such as satellite, High Altitude Platform Station (HAPS), general aviation, and helicopter. The primary barriers facing civil UAVs, stated by Starburst, were its expensive nature compared to satellite, limited coverage compared to other platforms, and usage limited by national regulations.

The value chain is dominated by three player types:

  • UAV OEMs and OES
  • UAV providers
  • Data analytic providers

The only company noted in the value chain who is strategically attempting to cover all areas is DJI, the largest Chinese UAV OEM with its renown Phantom and to a lesser extent, Inspire, brand UAVs.

Presently, the key inhibitors for UAVs are its expensive price points compared to satellite, limited yearly flight capacity (100 and 200 hours per year), limited battery technology which is prone to quickly degenerating, and restrictive regulations by aviation bodies in certain countries.

However, one of its key drivers is its enhanced capabilities for certain professions, such as monitoring pipelines.

Starburst predicts approximately 3,100 platform fleets will be active by 2030. In 2018, the firm believed 300 platform fleets were active.

Robot Aviation

Based in Norway, the firm developed UAV inspection capabilities for critical infrastructure assets, such as powerlines and/or search and rescue (SAR). The potential use of Inmarsat’s satcom systems will enable Robot Aviation to reduce mission planning, increase its UAV coverage area and also provide a more robust solution.

The implementation and practical usage of the UAV is still in its early stages and as such Robot Aviation have not yet completed any missions to date.

Robot Aviation are also developing and producing small to medium sized fixed wing UAVs for other commercial and military use. No further information was provided on the latter point.

The firm’s primary objective is to help the Norwegian SAR organisation with locating missing people. They only have 12 helicopters, and it is very taxing to complete the number of missions required in certain parts of the year. In 2018, the Norwegian SAR organisation completed 1994 missions, 817 of which were SAR.

In the UK, 2636 SAR missions took place in 2018.

Outcomes and Conclusions

With the introduction of Inmarsat’s satcom capabilities it will enable Robot Aviation to save time on mission planning, however, the savings on operational costs are unclear as no missions have been trialled.

It is also believed safety for the end-user will be increased and there will be less operational risk for those undertaking the SAR missions.

Silent Falcon

Based in New Mexico, USA.

The firm offers a class 2 small UAS which utilises solar electric for long endurance flights. Solar panels are located on the aircraft’s wings and top body enabling the system to fly for up to 8 hours, in optimal conditions. Relying solely on battery, the UAS’s flight time is limited to 4 hours.

Its primary applications are combatting wildland fire, land management, wildlife management, search and rescue, emergency management and intelligent surveillance and reconnaissance for border control, maritime, anti-poaching and narcotic interdiction.

They have been working to get the FAA’s 107 waiver. This allows them to fly UAVs BVLOS and at greater than 400 feet (133 metres) altitude. The FAA have been willing to grant such waivers for firefighting, search and rescue, incident awareness and analysis and utility and other critical infrastructure restoration.


Formed in 2013, the firm has 40 employees spread across Turkey and Ireland.

Its UAS system is an endurance drone, with flight times around 6 hours, and the use of a satcom systems allows it to be really maximise upon BVLOS applications such as pipeline inspections. Inmarsat and Cobham’s systems offers several advantages, one of which is the ability to fly close to the line and also transmit data from the UAS to headquarters live.

From A-techSyn’s perspective, its UAS solution is much more cost effective than using a helicopter, faster to deploy than a helicopter, safer than manned aircraft and thus increases safety for pipeline personnel. It can also use a fleet solution therefore deploying multiple UAVs over a pipeline route, and in effect, monitoring sections of a pipeline 16 hours a day, a flight operation every two hours. The firm has quoted BOTAS (Turkish state-owned company responsible for the country’s oil and gas pipelines) for a 3-year contract.

Alpha Unmanned Systems

Founded in 2014, the company sells and operates its UAV helicopter products. Indonesia and Israel are its main markets, addressing agriculture inspection and border control surveillance verticals.

Last year, the firm launched an Advanced Engineering service, and will launch a ResponseDrone, and new Alpha 900 models in 2019.

One of the key benefits for Alpha’s drones using the Aviator 200 UAV is the reliability of the connection. Radio Line-of-Sight is not always possible for the circumstances its clients require the drone to be used in.

The Alpha 800 is gasoline powered and has a range of 50km via radio. Its autonomous flight range is 3 hours and has a payload of 3kg. The firm has accumulated more than 3,000 hours of flight time.

With only a limited payload capacity of 3kg, the Aviation UAV 200 takes up half the platform’s weight capabilities. Nevertheless, future models will have greater payload carrying capacities, states Alpha.

Furthermore, satcom pricing will always be more expensive than direct radio link and service operators will likely use satcom as a back-up solution where radio is not possible.

One possibility is businesses moving to a leasing model, and potentially satcom costs could be incorporated into that leasing model.


  • As yet, no tangible benefits for the use of a satcom were revealed. Nevertheless, clear use cases for and why UAS service providers would use a satcom terminal as a communication channel are apparent.
  • SAR and critical asset inspection/surveillance seem to be the initial starting verticals for UAS incorporating satcom communications.
  • It is unlikely we will see much demand from media and other services, such as marketing material for real estates shots. It is also unclear the demand that agriculture will present for satcom UAS.
  • One significant potential market for UAS is likely to be goods delivery; particularly in regions with less developed infrastructure, such as some African and South American nations. UAS BVLOS may present a useful opportunity to compensate for any deficits in traditional infrastructure, hence such regions could provide a fertile market and an opportunity to demonstrate the capabilities of UAS BVLOS.
