3. A measurement taken from the UW Jacobson Observatory (Latitude: 47.660503°, Longitude: -122.309424°, Altitude: 220.00 feet) when its local sidereal time is 120.00° makes the following observations of a space object (Based on Curtis Problems 5.12 + 5.13): Azimuth: 225.00° Azimuth rate: 2.0000°/s. Elevation: 75.000° Elevation rate: -0.5000°/s Range: 1500.0 km Range rate: -1.0000 km/s a. What are the r & v vectors (the state vector) in geocentric coordinates? (Answer r = [-2503.47 v = [17.298 4885.2 5.920 5577.6] -2.663]) b. Calculate the orbital elements of the satellite. (For your thoughts: what type of object would this be?) (Partial Answer e = 5.5876, 0=-13.74°) Tip: use Curtis algorithms 5.4 and 4.2.

3. A measurement taken from the UW Jacobson Observatory (Latitude: 47.660503°,
Longitude: -122.309424°, Altitude: 220.00 feet) when its local sidereal time is 120.00°
makes the following observations of a space object (Based on Curtis Problems 5.12 +
5.13):
Azimuth: 225.00°
Azimuth rate: 2.0000°/s.
Elevation: 75.000°
Elevation rate: -0.5000°/s
Range: 1500.0 km
Range rate: -1.0000 km/s
a. What are the r & v vectors (the state vector) in geocentric coordinates?
(Answer
r = [-2503.47
v = [17.298
4885.2
5.920
5577.6]
-2.663])
b. Calculate the orbital elements of the satellite. (For your thoughts: what type of
object would this be?)
(Partial Answer e = 5.5876, 0=-13.74°)
Tip: use Curtis algorithms 5.4 and 4.2.
