This summer, I will continue research of the L2C GPS signal by developing tracking and navigation data decoding functions for the software defined receiver outlined in “A Software-Defined GPS and Galileo Receiver: A Single-Frequency Approach.”  Next, I plan to  gather dual frequency data and compare ionospheric estimates from a) current broadcast model b) research grade, dual frequency receiver c) SBAS ionospheric model and d) L2C model.
