Coherent Navigation provided high-precision GPS services (known as iGPS) that pair standard GPS signals with those from Iridium's (NASDAQ:IRDM) low-earth orbit satellite constellation to offer superior accuracy, signal integrity, and jamming protection. Whereas standard GPS is typically accurate to within several meters, Iridium and Boeing have claimed iGPS can be accurate to within centimeters.
Apple (NASDAQ:AAPL) has bought Coherent for an undisclosed sum. The purchase follows several 2013 acquisitions aimed at improving Apple Maps: Wi-Fi indoor positioning startup WiFiSlam, business/POI location database provider Locationary, commercial mapping services firm BroadMap, and public transit app developers HopStop, and Embark. More recently, Apple appears to have launched an effort to add street imagery similar to Google Maps' Street View.
Tim Cook disclosed in March Apple had bought 26 companies in the prior 15 months. As a list of Apple's known acquisitions shows, many of the purchases still haven't been made public.
