Info

8 RTK Mapping The status bar has two parts in which RTK status information is displayed. The bottom part of the status bar indicates the current mode of operation along with messages explaining the status of initialization. The mode of operation indicates the state of the current RTK position being sent from the GPS receiver. Table 8.4 lists the RTK status modes. Table 8.4 RTK status modes in Asset Surveyor Mode message Description Float The receiver is computing Float solutions. Solutions are precise to better than plus or minus a meter. Fixed The receiver is computing Fixed solutions. Solutions are precise to between 2 and 5 cm, depending on whether you are in roving or static mode. The top part of the status bar displays precision estimates indicating the horizontal and vertical precision of the current position as computed at the phase center of the antenna. The values displayed here provide a level of quality assurance, which, when monitored closely, offers information related to the appropriateness for RTK data collection within the current environment. For example, as the precision values rise, it is likely that environmental or satellite conditions are not as ideal for data collection as when they are low. Use the precision estimate values to help make judgments with respect to the reliability of a position for collection. 224 TSC1 Asset Surveyor Operation Manual
RTK Mapping 8 8.4.3 Recording Less Accurate Positions if the RTK Radio Link Fails At some stage the radio link between your base station and rover may fail, either because the batteries of the base station receiver or radio are flat, or due to some interference in the signal. By default, no positions are logged until the radio link is re-established. However, if necessary, you can configure the rover to switch to collecting less accurate positions (the same type of positions that you would collect using a non-RTK receiver such as the GPS Pathfinder Pro XR). To let your roving receiver record positions when the radio link fails, in the Real-time input form set the Choice 2 fieldto‘Useuncorrected GPS’. Note – RTK precision settings do not apply when Apply real-time is set to ‘Auto’. 8.4.4 Recording Non-RTK Data Files If you do not have access to an RTK base station, or do not want to collect RTK quality positions, you can still collect data files using an RTK receiver. The types of positions that you collect are the same as if you were using a non-RTK receiver such as the Pro XR. If your roving receiver has the RTCM option installed, you can record real-time differentially corrected positions as long as you have a radio link to an RTCM base station. If not, you can collect uncorrected (autonomous) positions and differentially correct them in the GPS Pathfinder Office software to obtain positions with submeter accuracy. To collect real-time, differentially corrected positions, set the Choice 1 fieldintheReal-time input form to ‘External source’ and set the Correction type fieldintheExternal source form to ‘RTCM’. Note – The <strong>Trimble</strong> 4400, 4700, and 4800 receivers always send the best available positions (that is, RTK positions will be sent if available.)
