Metr 415/715 Monteverdi Problem Set 1: Answer Key


Please make sure you answer in complete sentences and on separate sheets of paper.


Question 1:


I. Information Desired


Orbital radius (height above surface of earth) of geostationary satellite.


II. Equations Needed








III. Relations or Constants Needed





IV. Solution


For a geosynchronous orbit,


Fc = Fg                                                                (5)


Insert (1), (2), (3) and (4 b, d and e) into (5) and solve for R3


R3=7.501 X 1022  m3                     (6)


R=4.217 X 107  m3                       (7)


Substitute (4a and b) into (7) and solve for h


h=3.58 X 107  m3                          (8)


Question 2: The abbreviation GOES expands out to "Geostationary Operational Environmental Satellite."


Question 3: The subsatellite point for GOES-11 (aka GOES W) is 0o, 135o W and for GOES-32 (aka GOES E) is 0o, 75o W.


Question 4: The Cape Canaveral launch dates for GOES-11 (GOES-W) and GOES-13 (GOES-E) were May 3, 2000 and May 24, 2006, respectively.


Question 5: South America


Question 6:


Channel Wavelength (microns) Detection (Emitted or Reflected Radaition) Resolution (km) Operational Usefulness
