1. To prevent any confusion GPS coordinates of remote points always have an RP in front of the coordinate Also the azimuth value of the last measurement is frozen on the screen until the next laser shot is taken Similar to Azimuth Tilt mode the data output can be automatic or initiated by the DWNLD Download button Details on data output can be found in Section 8 13 Figure 8 Data displayed on LCD Screen for Laser Offset Mode example GPS INT 60 BAT 3 8 H INC and Range come from the laser AZIMUTH 220 0 INC 3 9 RANGE 38 0 F RP LAT N043 48 17 1634 RP refers to the RP LONG W079 26 48 6273 position of the Remote RP ELEV 648 6 F Point as seen through the laser ELEV refers to the elevation of the laser point above the WGS84 ellipsoid 11 8 4 Missing Line Mode This mode is a variation of Laser Offset mode in that the user can calculate the azimuth distance and inclination between two remote points When the Missing Line ML hotkey is pressed the user will be prompted to take a laser measurement to the first remote point After that measurement the APS will prompt for the laser measurement to the second point The APS will then calculate and display the Azimuth Inclination and Distance from the first remote point to the second remote point This is very useful for taking measurements is areas that the surveyor cannot physically occupy Similar to Azimuth Tilt mode the data output can be automatic or initi2. Also the APS should not be positioned to close to a vertical wall or under a tree which would cut down the sightlines to GPS satellites and potentially cause multipath interference although the APS has excellent multipath rejection capabilities 2 0 Features Accurate 0 5 True North Azimuth measurement No declination correction required Optional Bluetooth or cable to PDA Long Battery Life 6 5 hrs max Sub meter GPS Position Accuracy Performs without being affected by local magnetic anomalies Integrated GPS Integrity Parameter to qualify azimuth accuracy Measures the distance and azimuth between two targets using the built in Missing Line function Graphical satellite signal display on custom backlit LCD 3 0 On Board Sensors The APS produces an azimuth relative to True North no declination required and GPS position In addition there is an on board inclinometer to provide an accurate tilt angle When the optional Laser Rangefinder is attached TruPulse manufactured by Laser Technology http www lasertech com the APS can also determine the position and range to aremote point With the range and inclination information from the rangefinder the APS becomes a completely mobile total station with no need for setups and backsights which is ideal for Laser Offset mapping 4 0 System Overview Figure 1 System Overview Standard Outputs Azimuth True North Tilt Tilt of APS Station STN Position Inf
