# download cropped SmartLoc data file
glp.make_dir("../data")
!wget https://raw.githubusercontent.com/Stanford-NavLab/gnss_lib_py/main/data/unit_test/smartloc/tu_chemnitz_berlin_1_raw.csv --quiet -nc -O "../data/smartloc.csv"

# load smartLoc data into NavData object
smartloc_data = glp.SmartLocRaw("../data/smartloc.csv")

# plot the pseudorange over time of each individual satellite
# SBAS 120 is the outlier with its larger orbit
fig = glp.plot_metric(smartloc_data, "gps_millis","raw_pr_m", groupby="sv_id")
