Peter J. G. Teunissen (born 9 October 1957) is a Dutch geodesist,[3] known for his contributions to satellite navigation and Earth observation. He is particularly recognized for inventing the LAMBDA (Least-squares AMBiguity Decorrelation Adjustment) method, which has become the standard technique for solving integer ambiguities in GNSS carrier‑phase measurements.[4][1]

Early life and education
Teunissen was born in Owerri, Nigeria, on 9 October 1957. He earned his BSc (1978), MSc (1980, cum laude), and PhD (1985, cum laude) in Mathematical and Physical Geodesy from Delft University of Technology.[5]
Academic career
Teunissen has held several academic and leadership positions at Delft University of Technology (TU Delft), including Head of the Department of Geodesy, Vice-Dean of the Faculty of Civil Engineering and Geosciences, and Director of Education.[5]
He led the Earth Observation and Space Systems Department in the Faculty of Aerospace Engineering and later joined Curtin University in Perth, Australia, where he was the Foundation Head of the GNSS Research Centre and served as Science Director of the Cooperative Research Centre for Spatial Information (2009–2019).[6]
He has also served as Distinguished Visiting Chair Professor at Hong Kong Polytechnic University.[6]
Teunissen is currently emeritus Professor of Geodesy and Satellite Navigation at TU Delft and Vice-President of the International Association of Geodesy. He was the founding Editor-in-Chief of the Journal of Geodesy and serves on several editorial boards.[5]

Research
Teunissen is the originator of the Least-squares AMBiguity Decorrelation Adjustment (LAMBDA) method,[4][1] a key development in GNSS positioning. His research focuses on satellite navigation, mixed-integer estimation, quality control, and precise positioning with multi-GNSS constellations, including GPS, GLONASS, Galileo, BeiDou, and IRNSS.[5]
He has authored and co-authored numerous publications, including:
