8. la x El 2 s D ial N Surveying with ProMark2 57 Kinematic Surveying with the ProMark2 System The kinematic data collection process requires at least two receivers collecting data simultaneously One receiver is called the base and must remain stationary throughout the data collection Typically the base receiver will occupy a survey point for which the precise position is already known Once operational the base system simply collects and stores raw data from all satellites with line of sight to the GPS antenna The kinematic base is essentially the same as a static occupation except that the recording interval should be set to match that of the kinematic rover The other simultaneously operating GPS receiver during a kinematic survey is designated as the rover The rover unit s can move during the survey and are used to position new points relative to the base There are two types of kinematic survey supported by the ProMark2 system stop and go designated as stop n go in the receiver menus and continuous kinematic designated as kinematic in the receiver menus Stop and go surveying is best suited for collection of points During Stop and go the system is centered over a point and collects data for a period of time The occupation time for stop and go will typically range from 15 60 seconds It is highly recommended that a pole with bipod legs be used for Stop and go data collection to insure that the antenna is stabl

53. atic data collection the receiver must maintain lock on at least 5 satellites which are common at both the base and rover stations Ifthe receiver detects that less than 5 satellites are tracked it will send out an alarm indicating that the system must be reinitialized In cases of loss of lock due to obstructions it is possible that the accuracy of processed results will be degraded if re initialization is not performed in the field Therefore re initialization in the field 58 Promark2 User s Guide after a loss of lock is critical to maintaining survey accuracy Finally kinematic surveys are most successful when the kinematic base receiver is close to the kinematic rover Accuracies of GPS derived positions are distance dependent The greater the distance between the GPS receivers the larger the uncertainty In an ideal case the kinematic base should be on the same project site as the kinematic rover Kinematic surveys with a separation of more than 10 kilometers 6 miles between the kinematic base and rover should be avoided Such a separation makes kinematic initialization more difficult increasing the chances of poor results When performing a kinematic survey ProMark2 provides you with the tools to perform the following tasks e Manage data files in the GPS receiver Enter pertinent survey point attribute information required for data processing e Monitor the progress of the kinematic survey Stop and go or Kinematic Base Whe
