Survey Operations 16 February 2016 ATP 3-09.02 3-3 3-12. The mission of the subordinate unit requires it to initiate survey operations without waiting for survey control to be established by a higher echelon. Thus, a battalion assigned or attached to a FAB, DIVARTY, or BCT may have to operate first on the grid established by the battalion (battalion grid) and finally on the grid established by geodetic higher order survey section. When survey at one or more echelons is based on assumed data, data established by the lower echelon should be converted to the grid established by the higher echelon. An exception to this rule would be when prescribed accuracies are met or when the tactical situation, time constraints, or SOP causes the commander to decide otherwise 3-13. Whenever survey operations are started with an assumed azimuth, regardless of whether the coordinates and height are known or assumed, the coordinates of each station and the azimuths determined will be in error. To convert the assumed data to correct grid data, all azimuths and coordinates determined in the scheme must be corrected. 3-14. When using the forward observer system (FOS) device to convert assumed azimuth or coordinates to common control, use the following procedures: Display the SURVEY MODE MENU. Select the TRANSFORMATION MENU. Press the <A> key to select COORDINATE CONVERSION. Observe the COORDINATE CONVERSION SUMMARY LIST. Press the <Y> key and observe the TRANSFORMATION MENU. STOP. To print a survey form (DA Form 7368-R, Computation—Conversion UTM to GEO Coordinate, GEO to UTM Coordinate, Zone-to-Zone Transformation) of an existing record, press the <F> key. Select the letter key for the desired records. One of the following is printed depending on the type of coordinate conversion in the record: Universal Transverse Mercator (UTM) to Geographic (GEO) Coordinate. GEO to UTM. Zone-to-Zone Transformation. POSITION AREA SURVEY REQUIREMENTS 3-15. Survey control is required in the position area of each firing battery of a FA battalion. The FA battalion survey teams using the IPADS or IPADS-G. Position area survey requirements are identical for any type of artillery battery (see figure 3-1). Requirements for position area survey are described in paragraphs 3-17 through 3-23. Figure 3-1. Position area survey
