16 February 2016 ATP 3-09.02 2-1 Chapter 2 Survey Planning Planning for artillery surveys is based primarily on the planned positioning of firing units and target acquisition assets and the commander's accuracy requirements. This allows the commander to mass fires of subordinate units, to store and transfer target locations for future engagements, and to limit vulnerability of firing units. CONDUCT OF PLANNING 2-1. Surveys are planned to ensure that all required control is provided in the correct place and at the time required. The plan distributes work evenly among teams and eliminates duplicate work. Planning is based on meeting as many survey requirements as possible under the given conditions and always providing the best available survey control to using units. Survey control is critical; the survey plan must reflect the requirement to rapidly extend survey control throughout the AO. 2-2. Survey planning is conducted at all echelons at the same time. Provisions should be made to link together all surveys conducted in the area. The FFA HQ ties together the surveys of the firing and locating elements. The FFA HQ surveyors survey their organic and attached elements and help other units as directed. The degree of accuracy, speed of execution, and priority of work are given in the commander's guidance or are set by the S-3 from the commander's guidance. 2-3. Artillery units at all levels must start survey operations by establishing a common survey control point for initialization using the most accurate method available to the force. They do not wait for higher- echelon survey control to be established in the area. These methods may include using their onboard inertial navigation systems, conventional survey, IPADS or IPADS-G, Dual defense advanced global positioning system receiver (DAGR) Submil-D Kit, or simultaneous observation. Once more accurate survey capabilities are available these locations must be updated. Firing and target-locating units must work from the best available data and improve the data as higher-order survey becomes available. 2-4. Survey sections are organic to the FAB, DIVARTY, and FA battalion, target acquisition platoons. The survey section provides survey control for organic assigned and attached units. The survey section provides common direction, coordinates, and elevation data to all organic, attached, and reinforcing FA battalions, target acquisition assets, and the BCTs mortars as required. 2-5. For the purpose of planning a survey, installations may be separated into groups according to the accuracy of survey required. Requirements and position considerations are shown in table 2-1 on page 2-2. Fourth order. Fourth-order survey accuracy standard are 4.0 m horizontal circular error probable (CEP), 2.0 meters Vertical Probable Error and no more than 0.6 mil azimuth probable error. To maintain this accuracy IPADS or IPADS-G or Platform are required to perform zero velocity updates every 5 minutes. As a minimum 4 fourth order survey is required for Fires Brigade/Battalion SCP’s, and any firing unit firing precision guided munitions. Fifth order. Fifth-order survey accuracy standard are 7.0 m horizontal CEP, 3.0 meters Vertical Probable Error and no more than 0.4 mil azimuth probable error. To maintain this accuracy IPADS or Platform are required to perform zero velocity updates every 10 minutes. Fifth order survey is the minimum required by firing and target-locating units. Care must be used in selecting a method to establish direction for these installations. Hasty survey. All firing and target-locating elements requiring survey must be able to use hasty survey techniques to provide the best available survey control rapidly. For detailed information on hasty survey techniques see ATP 3-09.50.
