APPENDIX APPENDIX-1 APPENDIX 3 Dual Axis Compensation Inclination of the vertical axis with respect to tr ue v er tical will result in incorrectly measured horizontal angles. The e xtent of the error in horizontal angle measurement due to axis tilt depends on three f actors : ● the amount of the tilt of axis ● the elev ation of the target ● t[...]

APPENDIX APPENDIX-2 It is clear from the table that dual axis compensation has the most bene fi t when the ele v ation of the target is greater then 30° and the axis is tilted more than 10". The entr ies indicated in bold in the table sho w , in f act, that for man y common sur v eying applications i.e . target ele vation <30° and axis e[...]
