New Point Initialization The New Point method of kinematic initialization is the most time consuming method. It should be used only when other methods are not feasible. Observation times for initialization using the New Point method range from 15-30 minutes for a ProMark2 System. The observation time depends on the distance between the kinematic base and kinematic rover during initialization. The New Point initialization method is simply a static survey of the new point. Observation times should be consistant with those for performing a static survey. Processing of the data collected at the initialization point will produce a static vector between the kinematic base and rover, determining the precise position of the rover point. This in effect initializes the kinematic survey. Use the New Point initialization method when no other method is available for initializing your kinematic survey or in situations where you do not mind the time required to execute this initialization method. Data Collection With your ProMark2 receiver system set up over the point to be surveyed you are ready to begin data collection. This section provides you with the step-by-step process of using the user-interface of the ProMark2 to prepare the receiver to collect GPS data at this survey point. For further details on any screen presented in these procedures, go to Chapter 4, Detailed Screen Descriptions, and then locate the description for the particular screen of interest. 1. Turn on the ProMark2 receiver by pressing the red on/off button on the face of the receiver. The opening screen appears, followed by the Mode screen, Figure 3.29. Surveying with ProMark2 65 Surveying with ProMark2 The most common scenario for using the New Point method of initialization is when the kinematic base must be positioned away from the project site where the kinematic rover will be operating. For example, you need to perform your survey based on a control point located off the project site. In such a situation, you have two options. The first is to set up the kinematic base on the remote control site and initialize your kinematic rover on site using the New Point method. The second option is to first perform a static survey between the remote control point and a new control point on site. Then place the kinematic base on the new control point on site.
