Chapter 16, Problem

To determine

Develop the observation equations for the given baseline vectors

The observation equations for baseline components are:XB−R= 1,164,499.387+ v1YB−R= −4,660,600.879+ v2ZB−R= 4,182,158.213+ v3XT−H= 1,168,947.841+ v4YT−H= 4,650,766.249+ v5ZT−H= 4,191,851.263+ v6

Given that

Baseline vector are given as

Explanation:

Writing observation equation for X coordinate for jim to troy:

XB−R= XB+ ΔXB−R+v1

WHERE

X_B= X coordinate of the station bonnie = 1,161,121.599m

∆X_B_-_R= X component in baseline vector = 3.377.788m

∆₁= residual

XB−R=1,161,121.599+3.377.788+v1          = 1,164,499.387+ v1

Writing observation equation for Y coordinate for Bonnie to Ray:

YB−R= YB+ ΔYB−R+v2

WHERE

Y_B= Y coordinate of the station BONNIE = −4,655,872.977

ΔYB-R = Y component in baseline vector = −4,727.902

∆₂= residual

YB−R=−4,655,872.977+−4,727.902+v2          = −4,660,600.879+ v2

Writing observation equation for Y coordinate for Bonnie to Ray:

ZB−R= ZB+ ΔZB−R+v3

WHERE

Z_B= Z coordinate of the station bonnie = 4,188,330.232m

∆Z_B_-_R= Z component in baseline vector = −6,172.019m

∆₃= residual

ZB−R=4,188,330.232+−6,172.019+v3          = 4,182,158.213+ v3

Writing observation equation for X coordinate for tom to herb:

XT−H= XT+ ΔXT−H+v4

WHERE

X_T= X coordinate of the station Tom = 1,176,398.558m

∆X_T_-_H= X component in baseline vector = −7,450.717m

∆₄= residual

XT−H=1,176,398.558 −−7,450.717+v4          = 1,168,947.841+ v4

Writing observation equation for y coordinate for tom to herb:

YT−H= YT+ ΔYT−H+v5

WHERE

Y_T= Y coordinate of the station tom = -4,653,039.613m

∆Y_T_-_H= Y component in baseline vector = 2,273.364m

∆₅= residual

YT−H=−4,653,039.613+2,273.364+ v5          = −4,650,766.249+ v5

Writing observation equation for Z coordinate for tom to herb

ZT−H= ZT+ ΔZT−H+v6

WHERE

Z_T= Z coordinate of the station tom = 4,187,198.360m

∆Z_T_-_H= Z component in baseline vector = 4652.903m

∆₆= residual

ZT−H=4,187,198.360m +4652.903+v6          = 4,191,851.263+ v6

Conclusion:

Hence, the observation equations for baseline components are:

XB−R= 1,164,499.387+ v1YB−R= −4,660,600.879+ v2ZB−R= 4,182,158.213+ v3XT−H= 1,168,947.841+ v4YT−H= 4,650,766.249+ v5ZT−H= 4,191,851.263+ v6
