The LGA and Alignment frames are closely aligned as the tilt between them over the distances involved is small. 20.3 Gravitational Anomalies Figure 20-2 shows the gravitational acceleration error as a function of geodetic height at 53° latitude if Equation 20.2-6 is used rather than the more accurate expression in Equation 20.2-5. When doubly integrated over a long period of time the height error can be substantial, for example, an error of 2 km is induced at 20 km after 1 hr. The variation in gravity with geodetic height using the more accurate expression for the gravitational acceleration, ∂ g ZG p ∂ P ZG p For short-range applications, ZG p : = ZA p − 2 ⋅ g ZG p ⋅ ZG p ( ) 1 − P + P r, d ∂ g ∂ P ≅ ∂ g ∂ P ZG p d, p Equation 20.3-1 Equation 20.3-2 d
Appendix G / Gravity _ _ Ignoring small terms involving the earth rate the only significant variation in gravity with latitude is, GRAVITATIONAL ACCELERATION (M/S**2) GRAVITATIONAL ACCELERATION ( M/S**2 ) 9.84 9.83 9.82 9.81 9.8 9.79 ∂ g ∂ λ ZG p d : = 0. 10372 20-7 ⋅ ϕ ⋅ sin λ ⋅ cos λ 9.78 0 10 20 30 40 50 60 70 80 90 LATITUDE (DEGREES) 9.82 9.81 9.8 9.79 9.78 9.77 9.76 9.75 9.74 9.73 Figure 20-3 : Gravity vs Latitude 9.72 0 5 10 15 20 25 30 GEODETIC HEIGHT ( KM ) Figure 20-4 : Gravity vs Height 1 d d Equation 20.3-3 The variation in gravitational acceleration with latitude and geodetic height is shown in Figure 20-3 and Figure 20-4 respectively. At a latitude of 45° the gravitational acceleration at sea-level is 9.8067m/s 2 .
