Question 1:

I. Information Desired

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

II. Equations Needed

(1)

(2)

(3)

III. Relations or Constants Needed

(4)

IV. Solution

For a geosynchronous orbit,

F_{c} = F_{g (5)
}

_{
}

_{Insert (1), (2), (3) and (4 b, d and e) into (5) and solve for R}^{3}

R^{3}=7.501 X 10^{22} m^{3} (6)

R=4.217 X 10^{7} m^{3} (7)

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

h=3.58 X 10^{7} m^{3} (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 0^{o}, 135^{o} W and for GOES-12 (aka GOES E) is 0^{o}, 75^{o} W.

Question 4: The Cape Canaveral launch dates for GOES-11 (GOES-W) and GOES-12 (GOES-E) were May 23, 2000 and July 23, 2001, respectively.

Question 5: GOES-O: August 2008; GOES-P: October 2008
