Santa Struggles with Radio Frequency Interference – Could Hinder Gift Delivery

Santa Calling about Radio Frequency InterferenceWhen my caller ID lit up showing an incoming call from “The North Pole” I scratched my head wondering who it could be. Only one person I know of lives at The North Pole. Yup, it was Santa. In the past, Santa has worked with ANSYS engineers to improve the structural and aerodynamic properties of his sleigh. This year, Santa had another concern that he was calling me about. It seems that on some test flights in preparation for this year’s Christmas Eve deliveries, Santa noticed that the sleigh’s on-board GPS radio that he and his elves rely on for accurate tracking information wasn’t always working properly. Santa noticed that the problem usually occurred when he flew near cell phone base station towers. We assured Santa that we could help and we set about modeling the installed radio frequency (RF) systems on his sleigh in order to understand what was happening. Continue reading
