CP 13- BM 1

Azimuth (βBM1+ α CP13) - 180˚ = (300˚52’58” +71˚23’57”) - 180˚              = 192˚16’55”

Jarak Optis antara CP 13 – BM 1  = (1.770 – 1.678) x 100                             = 9.20 m

Jarak Optis antara CP 13 – BM 1  = (cos²  . 88˚24’58” ) x 9.20                      = 9.19 m

Beda Tinggi antara CP 13 – BM 1((sin  . 88˚24’58” ) x 9.20)+(1.492-1.725)  = 0.021 m

Δx CP13-BM 1  (D x sin α CP13-BM1) = (9.19m + 192˚16’55”)                     = -1.955

Δy CP13-BM 1  (D x cos α CP13-BM1) = (9.19m + 192˚16’55”)                    = -8.981

BM1 = Koordinat CP13 (X) + Δx BM1     = 636279.1m + -1.955                    =636277.2

BM1 = Koordinat CP13 (Y) + Δy BM1     = 9158676.1m+ -8.981                   =9158667.1
