Per Enge




Per Enge is a Professor of Aeronautics and Astronautics at Stanford University, where he is the Kleiner-Perkins, Mayfield, Sequoia Capital Professor in the School of Engineering. He directs the GPS Research Laboratory, which develops satellite navigation systems based on the Global Positioning System (GPS). These navigation systems augment GPS to improve accuracy and provide real time error bounds. In addition, the laboratory is developing a suite of technologies to mitigate the navigator's vulnerability to radio frequency interference. The laboratory has pioneered two such systems that are now operational. The first system uses a network of medium frequency radiobeacons to broadcast differential GPS corrections to maritime and land users. This system was developed for the U.S. Coast Guard, and today it covers much of the world's coastline and an increasing inland area. It provides differential GPS data to approximately 1.5 million users. The second is the Wide Area Augmentation System (WAAS) that was developed for the FAA. WAAS already serves millions of users, and became operational for aircraft in 2003. The laboratory is currently working on auto-land systems based on GPS. Foremost amongst these is the Local Area Augmentation System (LAAS) which supports larger airplanes at high-traffic hub airports. Per has received the Kepler, Thurlow and Burka Awards from the Institute of Navigation (ION) for his work. He is also a Member of the National Academy of Engineering as well as a Fellow of both the ION and the Institute of Electrical and Electronics Engineers (IEEE). He received his PhD from the University of Illinois in 1983, where he designed a direct-sequence multiple-access communication system that provided an orthogonal signal set to each user.
