Mr.Radar

Given the radar pulse returns of a satellite, determine its orbital parameters (assume two-body dynamics). Each pulse has been provided as:

t, timestamp (UTC)
az, azimuth (degrees) +/- 0.001 deg
el, elevation (degrees) +/- 0.001 deg
r, range (km) +/- 0.1 km

The radar is located at Kwajalein, 8.7256 deg latitude, 167.715 deg longitude, 35m altitude.

Estimate the satellite's orbit by providing the following parameters:

a, semi-major axis (km)
e, eccentricity (dimensionless)
i, inclination (degrees)
Ω, RAAN (degrees)
ω, argument of perigee (degrees)
υ, true anomaly (degrees)
