And that part seems entirely reasonable. It looks like the Tomahawk cruise missile did it with an 84 lb package with a 16-bit computer with 64K of memory [1] [2] and sensors. That's similar computing performance to an original IBM PC, which weighed 30 lb. The only bit of hardware an iPhone doesn't seem to have for TERCOM is a radar altimeter, but it looks like those are available for civil aviation.
