Used during the field data collection portion of this project, the Method had I selected US Survey Feet, and specified US State Plane 1983, California Zone 2Ġ402, NAD 1983 (Conus) ( Moldensky), GEIOD09 (Conus). Of the hour long GPS observations, and Session 2 consisted of the 30 minute GPS Two separate TBC projects were created GPS PROJECT SESSION1 and GPS The OPUS files are available in the Appendix.Īfter downloading the receiver data files, Trimble BusinessĬenter was used to process the raw GPS data. The OPUS files are emailed to my email account. Reference point (ARP) was calculated using a Excel spreadsheet I createdĬonverting the slant height to the ARP. In the file name designate the receiver name, the last 4 digits designate theįile and the. The data from both GPS receivers were downloaded using the Prior to starting the survey the tribrach and the prism pole wasĬollected and recorded in a field notebook in both meters and US Surveyįield notes are available in the Appendix. Reasons the 150 meter monuments were chosen. Originally the 0 meter and theġ000 meter monuments were going to be used for this project, but due to security Sacramento was used as the study area for this project. The newly constructed Calibration Base Line (CBL) in Trimble Business Center (TBC) version 2.3 was used to process the GPS
