The Global Positioning System Laboratory (GPSL) at Cornell University investigates
Global Navigation Satellite Signals for the purpose of remote sensing of the space
environment, to improve the reliability and integrity of GPS positioning in the presence
of space weather, to detect and mitigate jamming and spoofing of GPS, and to advance GNSS
receiver technology. GPSL is an
interdisciplinary group composed of faculty, students, and staff who design
and build GPS receivers, evaluate and test these receivers in both terrestrial
and space environments, and teach courses in the design of GPS receivers.
The GPSL, along with the School of Electrical and Computer Engineering and
the Sibley School of Mechanical and Aerospace Engineering, sponsor
courses in receiver design and a weekly seminar. GPS Receiver Design: Theory
and Design (ECE/MAE 4150) is
an introduction into GPS receiver technology and algorithms starting with the
GPS observables, and concluding with the determination of position and errors
using MATLAB algorithms. Advanced GPS Receiver Design
(MAE 6950) begins with the
GPS signal digitized at base band and develops algorithms for acquisition,
tracking, and extraction of the GPS observables.
Graduate research is directed by individual faculty members but often
students will work with multiple faculty members to achieve their goals.
Dissertation topics include development of software receivers and
algorithms for advanced applications such as precision navigation in space,
imaging of ionospheric irregularities, evaluation of the effects of space
weather, and optimal acquisition and tracking.
