Above-mentioned true azimuth A ₁₂Be standpoint P ₁With tested point P ₂Place straight line P ₁P ₂True azimuth.During actual measurement, true azimuth A ₁₂For from standpoint P ₁Real north (being the true meridian the North) vector P ₁N is rotated clockwise to straight line P ₁P ₂Horizontal angle.

Step 4, tested point P ₂Geographic coordinate convert: combine standpoint P ₁Geographic coordinate P ₁(B ₁, L ₁) and tested point P ₂True azimuth A ₁₂, and according to formula

$B_2=B_1+\frac{v^3}{c}\mathrm{Cos}{A}_{12}-\frac{v^{4}t}{c^2}({3\mathrm{\η}}^2{\mathrm{Cos}}^2{A}_{12}+{\mathrm{Sin}}^2{A}_{12})-\frac{v^5}{c^3}\mathrm{Cos}{A}_{12}[{\mathrm{Sin}}^2{A}_{12}(1+{3t}^2+{\mathrm{\η}}^2-9{\mathrm{\η}}^2{t}^2)+$ With

${3\mathrm{\η}}^2{\cos }^2{A}_{12}({1-t}^2+{\mathrm{\η}}^2-5{\mathrm{\η}}^2{t}^2)]$

$L_2=L_1+\frac{v}{c}{\sec B}_1{\sin A}_{12}+\frac{{2v}^{2}t}{c^2}{\sec B}_{1}s{\mathrm{inA}}_{12}{\cos A}_{12}+\frac{{2v}^3}{c^3}{\sec B}_1[{\sin A}_{12}{\cos }^2{A}_{12}({1+3t}^2+{\mathrm{\η}}^2)-t^2{\sin }^3{A}_{12}]$

Calculate tested point P ₂Geodetic latitude B ₂With geodetic longitude L ₂In the formula, t=tanB ₁, $v=\sqrt{{1+\mathrm{\η}}^2}=\sqrt{{1+e}^{\′2}{\mathrm{Cos}}^2{B}_1},$ $c=\frac{a^2}{b}=\frac{a}{\sqrt{1-e^2}},$ Wherein e is first excentricity of earth ellipsoid, and e' is second excentricity of earth ellipsoid, and a and b are respectively the major semi-axis length and the minor semi-axis length of earth ellipsoid.

Above-mentioned formula:

$B_2=B_1+\frac{v^3}{c}\mathrm{Cos}{A}_{12}-\frac{v^{4}t}{c^2}({3\mathrm{\η}}^2{\mathrm{Cos}}^2{A}_{12}+{\mathrm{Sin}}^2{A}_{12})-\frac{v^5}{c^3}\mathrm{Cos}{A}_{12}[{\mathrm{Sin}}^2{A}_{12}(1+{3t}^2+{\mathrm{\η}}^2-9{\mathrm{\η}}^2{t}^2)+$ With

${3\mathrm{\η}}^2{\cos }^2{A}_{12}({1-t}^2+{\mathrm{\η}}^2-5{\mathrm{\η}}^2{t}^2)]$

$L_2=L_1+\frac{v}{c}{\sec B}_1{\sin A}_{12}+\frac{{2v}^{2}t}{c^2}{\sec B}_{1}s{\mathrm{inA}}_{12}{\cos A}_{12}+\frac{{2v}^3}{c^3}{\sec B}_1[{\sin A}_{12}{\cos }^2{A}_{12}({1+3t}^2+{\mathrm{\η}}^2)-t^2{\sin }^3{A}_{12}]$

Derivation following:

Known standpoint P ₁Geographic coordinate P ₁(B ₁, L ₁), standpoint P ₁To tested point P ₂Geodesic line length S (can by horizontal range HD replace), use geodetic azimuth A ₁₂Separate and ask tested point P ₂Terrestrial coordinate P ₂(B ₂, L ₂).

According to Maclaurin series with P ₁And P ₂2 the meridional difference, warp differ from and the angle of cut, all expand into the power series of geodesic line length S:

$b=B_2-B_1={\left(\frac{\mathrm{dB}}{\mathrm{dS}}\right)}_{S=0}S+{\left(\frac{d^{2}B}{{\mathrm{dS}}^2}\right)}_{S=0}\frac{S^2}{2}+{\left(\frac{d^{3}B}{{\mathrm{dS}}^3}\right)}_{S=0}\frac{S^3}{6}+\·\·\·;$

$l=L_2-L_1={\left(\frac{\mathrm{dL}}{\mathrm{dS}}\right)}_{S=0}S+{\left(\frac{d^{2}L}{{\mathrm{dS}}^2}\right)}_{S=0}\frac{S^2}{2}+{\left(\frac{d^{3}L}{{\mathrm{dS}}^3}\right)}_{S=0}\frac{S^3}{6}+\·\·\·;$

B, L and A are the functions of B and A to the all-order derivative of S in above-mentioned three formula, and locate value in geodesic line starting point (S=0), promptly with B=B ₁, A=A ₁₂The value substitution try to achieve.

Wherein, the first order derivative in above-mentioned three formula is the differential relationship of geodesic line, that is:

$\frac{\mathrm{dB}}{\mathrm{dS}}=\frac{1}{M}\cos A=\frac{v^3}{c}\cos A;$

$\frac{\mathrm{dL}}{\mathrm{dS}}=\frac{1}{N\cos B}\sin A=\frac{v}{c}\sec B\sin A;$

$\frac{\mathrm{dA}}{\mathrm{dS}}=\frac{\tan B}{N}\sin A=\frac{v}{c}t\sin A;$

Auxiliary quantity in the differential relationship of above-mentioned three geodesic lines:

t=tanB，η ²=e' ²cos ²B， $v=\sqrt{{1+\mathrm{\η}}^2}=\sqrt{{1+e}^{\′2}{\cos }^{2}B},$ $c=\frac{a^2}{b}=\frac{a}{\sqrt{1-e^2}},$ $N=\frac{a}{\sqrt{1+e^{2}s{\mathrm{in}}^{2}B}},$ $M=\frac{a(1-e^2)}{{(1+e^2{\sin }^{2}B)}^{\frac{3}{2}}};$

Obviously just have:

$\frac{\mathrm{dV}}{\mathrm{dB}}=-\frac{{\mathrm{\η}}^{2}t}{V},$ $\frac{\mathrm{dt}}{\mathrm{dB}}=1+t^2,$ $\frac{{\mathrm{d\η}}^2}{\mathrm{dB}}=-{2\mathrm{\η}}^{2}t;$

In the differential relationship according to above-mentioned three geodesic lines continued S differentiate process, the variation that should be taken into account S was caused by the variation of B and A, therefore just had:

$\frac{d^{2}B}{d{S}^2}=\frac{\∂}{\∂B}\left(\frac{\mathrm{dB}}{\mathrm{dS}}\right)\frac{\mathrm{dB}}{\mathrm{dS}}+\frac{\∂}{\∂A}\left(\frac{\mathrm{dB}}{\mathrm{dS}}\right)\frac{\mathrm{dA}}{\mathrm{dS}}$

$=\frac{\cos A}{c}{3v}^2(-\frac{{\mathrm{\η}}^{2}t}{v})\frac{v^3}{c}\cos A+(-\frac{v^3}{c}\sin A)\frac{v}{c}t\·\sin A$

$=-\frac{v^{4}t}{c^2}({3\mathrm{\η}}^2{\cos }^{2}A+{\sin }^{2}A)$

Draw similarly:

$\frac{d^{2}L}{{\mathrm{dS}}^2}=\frac{2v^{2}t}{c^2}\sec B\sin A\cos A;$

$\frac{d^{2}A}{{\mathrm{dS}}^2}=\frac{v^2}{c^2}\sin A\cos A(1+{2t}^2+{\mathrm{\η}}^2);$

Differentiate can draw three order derivatives once more:

$\frac{d^{3}B}{{\mathrm{dS}}^3}=-\frac{v^5}{c^3}\cos A[{\sin }^{2}A({1+3t}^2+{\mathrm{\η}}^2-9{\mathrm{\η}}^2{t}^2)+3{\mathrm{\η}}^2{\cos }^{2}A(1-t^2+{\mathrm{\η}}^2-5t^2{\mathrm{\η}}^2)];$

$\frac{d^{3}L}{{\mathrm{dS}}^3}=\frac{{2v}^3}{c^3}\sec B[\sin A{\cos }^{2}A({1+3t}^2+{\mathrm{\η}}^2)-t^2{\sin }^{3}A];$

$\frac{d^{3}A}{{\mathrm{dS}}^3}=\frac{v^{3}t}{c^3}[{\cos }^{2}A\sin A(5+6t^2+{\mathrm{\η}}^2-4{\mathrm{\η}}^4)-{\sin }^{3}A(1+2t^2+{\mathrm{\η}}^2)];$

Thereby have:

$B_2=B_1+\frac{v^3}{c}\cos A-\frac{v^{4}t}{c^2}({3\mathrm{\η}}^2{\cos }^{2}A+{\sin }^{2}A)-\frac{v^5}{c^3}\cos A[{\sin }^{2}A(1+{3t}^2+{\mathrm{\η}}^2-9{\mathrm{\η}}^2{t}^2)+$

${3\mathrm{\η}}^2{\cos }^{2}A({1-t}^2+{\mathrm{\η}}^2-5{\mathrm{\η}}^2{t}^2)]$

$L_2=L_1+\frac{v}{c}\sec B\sin A+\frac{{2v}^{2}t}{c^2}\sec Bs\mathrm{inA}\cos A+\frac{{2v}^3}{c^3}\sec B[\sin A{\cos }^{2}A({1+3t}^2+{\mathrm{\η}}^2)-t^2{\sin }^{3}A];$

Because A=A ₁₂, B=B ₁, t=tanB, $v=\sqrt{{1+\mathrm{\η}}^2}=\sqrt{{1+e}^{\′2}{\mathrm{Cos}}^{2}B},$ $c=\frac{a^2}{b}=\frac{a}{\sqrt{1-e^2}},$ Then have:

$B_2=B_1+\frac{v^3}{c}\cos A_{12}-\frac{v^{4}t}{c^2}({3\mathrm{\η}}^2{\cos }^2{A}_{12}+{\sin }^2{A}_{12})-\frac{v^5}{c^3}\cos A_{12}[{\sin }^2{A}_{12}(1+{3t}^2+{\mathrm{\η}}^2-9{\mathrm{\η}}^2{t}^2)+$

${3\mathrm{\η}}^2{\cos }^2{A}_{12}({1-t}^2+{\mathrm{\η}}^2-5{\mathrm{\η}}^2{t}^2)]$

$L_2=L_1+\frac{v}{c}{\sec B}_1{\sin A}_{12}+\frac{{2v}^{2}t}{c^2}{\sec B}_{1}s{\mathrm{inA}}_{12}{\cos A}_{12}+\frac{{2v}^3}{c^3}{\sec B}_1[{\sin A}_{12}{\cos }^2{A}_{12}({1+3t}^2+{\mathrm{\η}}^2)-t^2{\sin }^3{A}_{12}]$
