Easy error analysisKinematic data processingEach result is displayed on the screen with an errorellipse. Problem lines are identified immediately bycolor codes for further analysis, making theidentification of problematic baselines effortless.The software supports both kinematic andcontinuous data. On-the-fly ambiguity resolution isavailable, which processes kinematic data without anyperiod of static initialization. This is especially usefulin applications such as aerial photogrammetry.Trimble Total Control software allows you tointerpolate the position at time of exposure forphotogrammetric flights. The positions of eventmarkers are interpolated almost instantly, makingprocessing airborne GPS data effortless! Results canbe given in a local, national or state plane coordinatesystem.Baseline results are available in detail or summaryAs all surveyors know, keeping a record of all surveyprocessing is extremely important. The full set ofresults can be displayed and saved automatically to afile for future use. These include L1-only, L2-only,wide-lane, ionosphere-free, GLONASS and othercombinations. The results include the data forvariance-covariance matrices used in the networkadjustment, standard errors, and best and worstPDOP and RDOP during the measurement session.The results report can be user defined so that onlyvalues of immediate interest are shown.TECH NOTESGraphical analysisBaseline results reportGraphical analysis and editingGraphical analysis and editing features give youcomplete control over the data, as well as provide thein-depth analysis needed in many survey applications.Lines on which multipath interference from buildingsor trees is suspected can have sections of bad datadisabled so that they are ignored in future processing.You can edit the data satellite-by-satellite. You can alsodefine the satellites used, elevations and observationintervals for each line. The locations of cycle slips aredisplayed, although the software corrects for theseautomatically during processing.Residual analysis5
