The main objective of this Bachelor's Thesis was to determine the most suitable service among Iridium Certus 100, Short Burst Data (SBD), and Router-Based Unrestricted Digital Internetworking Connectivity Solutions (RUDICS) for the Ocean Access submersible buoy project. Ocean Access sought to identify the optimal service based on different use cases, with each use case contingent upon the selected service and further defined through the course of the thesis work. The selection of the service would be based on the type of data being collected, the geographical location, and the required frequency of transmission. During the project, successful implementation of the SBD service was achieved in the existing software infrastructure. However, due to the availability of modules and pre-existing manufacturer implementations, the consideration of Iridium Certus 100 and RUDICS were confined to theoretical evaluations. Nevertheless, the thesis played a helpful role in assisting Ocean Access in identifying the specific use cases where each of the three services could offer valuable contributions to their research. Additionally, the thesis provided a pathway and guidelines for the future implementation of the remaining two services, Iridium Certus 100 and RUDICS, in their endeavors.
