“…The heart of any observation system is its sensors. The variety of sensors used on autonomous platforms has been growing for more than two decades (Schofield et al, 2010;Tintoré et al, 2013;Marques et al, 2018;Testor et al, 2018). These capabilities are driven by the need to characterize the ocean comprehensively and in near real-time (Zappalà et al, 2016).…”

“…19 Several institutions are making progress toward integrated systems of heterogeneous platforms focusing on persistence in the maritime environment 20 (Braga et al, 2017;Schmidt Ocean Institute, 2018). Many experiments have demonstrated heterogenous networks of autonomous platforms working together (Schofield et al, 2010;Huet and Mastroddi, 2016;Centurioni et al, 2017;Lindstrom et al, 2017;Marques et al, 2018;Phillips et al, 2018;Testor et al, 2018). Military trials, as depicted in Figure 5, also demonstrated interoperable communications using a standard protocol for underwater digital acoustic communications (LePage et al, 2015), and adaptation of sensors and systems based on real-time environmental conditions (LePage, 2018).…”

Whitt et al. Future of Autonomous Ocean Observations reductions. Cost reductions could enable order-of-magnitude increases in platform operations and increase sampling resolution for a given level of investment. Energy harvesting technologies should be integral to the system design, for sensors, platforms, vehicles, and docking stations. Connections are needed between the marine energy and ocean observing communities to coordinate among funding sources, researchers, and end users. Regional teams should work with global organizations such as IOC/GOOS in governance development. International networks such as emerging glider operations (EGO) should also provide a forum for addressing governance. Networks of multiple vehicles can improve operational efficiencies and transform operational patterns. There is a need to develop operational architectures at regional and global scales to provide a backbone for active networking of autonomous platforms.

“…The targeted area was the outfall of the Sado estuary, planning to correlate AUVs, UAVs, moorings and remote sensing data. This scenario was successfully executed in a previous exercise edition, in 2017 [8]. The systematic studies of this kind, contributes for a better understanding of the phenomenon being observed, building time-series of data, and helping understand its impact on the stratification of the water column in the region [9].…”

We describe the 2018 edition of the Recognised Environmental Picture exercise (REP18). Every year, the Portuguese Navy hosts an international exercise where challenging and novel operational scenarios are tested in a controlled environment. This is done to achieve a readiness level that allows the use of those developments in future real-world scenarios. The objectives range from military to different scientific purposes, always aiming for the use of innovative though operational technologies. In this paper we document the 2018 objectives and results, as well as innovations that helped resolving the challenges posed by this operational environment enriched by multiple heterogeneous vehicles.Index Terms-Marine operations, Autonomous Underwater Vehicle, Unmanned Aerial Vehicle, Autonomous Vehicle Network

“…The institution has, over the last 20 years, successfully fielded unmanned air, ground, surface and underwater vehicles in the Atlantic and Pacific oceans, and also in the Mediterranean and North seas. Moreover, its current active cooperation protocol with the Portuguese Navy allows for the deployment of large scale yearly exercises [20], [21], [22], [23] which serve as an operational testing event with active stakeholders and practitioners with the capability of validating the proposed concepts of operation (CONOPs).…”

With the rise in the use of multi-vehicles teams, for maritime operations, new challenges and opportunities arise regarding the complexity and logistics of these scenarios. One way to cope with said complexity is to imbue some of these systems with the versatility of operating in more than one physical medium (air/water/land) during its normal mission cycle, maximizing their possible mission roles. The ability of having a vehicle which can operate both in the air and on the water can further expand and facilitate maritime operations by allowing new sampling, deployment and even communication scenarios. This work follows the iterations of a specific vehicle concept, through its various phases, and tracks the developments and challenges necessary to adapt a Remotely Piloted Aircraft Systems (RPAS) to become capable of water take-off & landing, and explores its applicability as a viable operational mobile communication gateway for underwater and surface assets.
