Closing out this month’s #researchfeatures with Jaakko Yliaho!
“I am an electrical engineer interested in electronics, embedded and distributed systems, RF and accurate time. The technical side of space domain has very often connection to at least some of those fields.
My research interest is related to satellite positioning in general and especially opportunistic positioning using space-based communication signals as an additional source for positioning information. Basically, this means doing positioning and navigation with radio frequency signals that were not designed nor meant for positioning use. This kind of communication signals have in the recent years become popular and the number of satellites transmitting this kind of signals from low-earth orbits is already very high.
Using additional positioning signals to complement Galileo, GPS and other global navigation satellite systems (GNSS) increases the positioning robustness. Users, authorities and the global positioning community are actively working on dealing with the increased amount of interference on GNSS signals. Having available additional positioning technologies, like space-based opportunistic positioning, could provide the users with better trust on always available positioning and navigation.”
