Ground-Based Sense And Avoid (GBSAA)
Purpose and goal
Ground-Based Sense And Avoid (GBSAA) is the name of an innovation and a system that allows drones and its remote pilot to "see" manned aircraft and avoid them if necessary. The GBSAA also enables the drone to be "visible", ie manned aircraft will be alerted to the drone. GBSAA bring significant benefits to applications based on beyond line of sight operations as the system reduces the risk for those type of flight missions. The goal of the project was to implement a system that can be used in sharp tests and for permitting authorities to evaluate. It has been fulfilled.
Expected results and effects
GBSAA is currently being evaluated by the authorities. In the long term, we expect that flights beyond line of sight will become a rule rather than an exception, but then safety must be addressed. GBSAA is a system that increases the safety of beyond line of sight applications.
Planned approach and implementation
The technology behind GBSAA is based on ADS-B (Automatic Dependent Surveillance-Broadcast), an international standard for air traffic separation, basically for aircraft and craft control tower to "see" each other. The knowledge about ADS-B and the regulations linked to that technology have been absolutely crucial to the project´s success.
