This paper describes a new solution for alternative navigation services in oceanic airspace, using collaborative methods, enabled by air-to-air ranging in future navigation technologies. Improving the performance of alternative services is particularly desirable in oceanic airspace, as the demand for slots in the existing organized track systems starts approaching their capacity. The results show how this technology can help support a single aviation user suffering an on-board outage of satellite navigation, or how it could bridge a large-scale regional outage up to 3000 km wide.
