Introduction Leica Geosystems GPS System 500 comprises of GPS receiver hardware and PC based software for GPS Surveying and related applications. The Main components are: • GPS Receiver: Receive the satellite signals. • GPS Terminal: Keyboard and Display device to steer the Receiver • Post-processing software: Used to process GPS data. All of the instructions you need in order to operate your GPS system to a basic level are contained in this user manual. GPS Equipment User Manual -2.0.
System description Post-processing software GPS Receiver The GPS Receiver receives the GPS signal from the NAVSTAR satellites and calculates a range to all visible satellites. There are various types of Receivers available: SR510 - 12 L1 channels, code and phase SR520 - 12 L1, 12 L2 channels, code and phase SR530 - 12 L1, 12 L2 channels, code and phase, RTK capable. System description The AT502 Antennas are intended for use with the SR520 and SR530 Receivers.
Getting started with new equipment SKI-Pro (SKI-Pro-L1) post-processing software Receiver Hardware In most cases, the software will be installed by the local Leica Geosystems representative and a short introductory course will be given. In most cases, a short introduction in the use of the Receiverand Terminal will be provided by the local Leica Geosystems representative. If this is not the case proceed as outlined in the following sections.
Charge the batteries Charge the batteries with the Leica Geosystems battery charger provided. GEB121, GEB70 or GEB71 batteries may be used to power the GPS equipment. The battery chargers are intended for indoor use only. Use a battery charger in a dry room only, never outdoors. Charge batteries only at an ambient temperature between 10°C and 30°C ( 50°F to 86°F ). We recommend a temperature of 0°C to +20°C (32°F to 68°F) for storing the batteries.
Set Up the Equipment Successful GPS surveys require undisturbed satellite signal reception. This means that GPS Receivers should be set up in locations which are free of obstructions. No obstacles like trees, buildings, mountains, etc. should block the line between the GPS antenna and GPS satellites. This holds true in particular for the Receiver which serves as the reference. For static and rapid static surveys, the antenna must be kept perfectly steady throughout the whole occupation of a point.
Measuring with the default configuration parameters Step 1: Power on Step 2: Study the Icons Turn on the sensor by pressing the ON-button on the terminal. One of the following two screens will appear on the display: Most important at this stage is the top part of the screen which contains several symbols (icons) which indicate the current system status. Getting started with new equipment 10 GPS Equipment User Manual -2.0.
Measuring with the default configuration parameters, continued Upon power on you will first recognize the Number of visible Satellites icon, indicating the number of satellites which are theoretically visible at the current location and time. Usually this number varies between 4 and 9, depending on the satellite geometry. Next to this symbol you find the Number of Satellites used on L1 / L2 icon, indicating the number of satellites currently tracked either on L1 or on L2.
Measuring with the default configuration parameters, continued The Battery Status icon at the right side of the icon line shows from which source the sensor is currently powered. A and B indicate the internal batteries, E an external battery source. The symbol also indicates the voltage level of the currently used battery in 4 different stages from "full" (fully black) to 2/3 to 1/3 and "almost flat" (white colour). You cannot proceed from here if no memory device is available.
Measuring with the default configuration parameters, continued You are now in the Utilities \ Format Memory Module panel: If you want to format the PC-card just press F1 CONT to format the card. If you want to format the internal memory press ENTER. A list-box opens which allows you to select the internal memory. Use the cursor key to highlight Internal, then press ENTER. Then press F1 CONT in order to start the formatting process of the internal memory.
Measuring with the default configuration parameters, continued Step 4: Begin a Survey Enter the Survey operation by either pressing 1 in the Main\ panel or by first navigating to 1 Survey via cursor keys and then pressing ENTER or F1 CONT. The following panel will appear: Some basic decisions have to be made in this panel: Which configuration set should be activated, which job the raw data should be stored and which antenna set-up should be used.
Measuring with the default configuration parameters, continued Now use the cursor up or cursor down key on the terminal to highlight the PP_STAT line. Then press ENTER or F1 CONT. Use the cursor up or cursor down key to highlight the input field for jobs. Then press ENTER. The following listbox will appear: Now press F2 NEW. The following panel appears: Jobs are used to organise and structure the data you collect in the field.
Measuring with the default configuration parameters, continued You can now enter a name for a new job; press ENTER upon completing the input of the name. Input fields for description and creator are optional and can be left blank. By default the new job will be assigned to the PC-card. If needed this can be changed to Internal by toggling the Device input field to Internal. As an example we can create a new job called Test: Pressing F1 CONT which confirms the creation of a new job name and its location.
Measuring with the default configuration parameters, continued Now press F1 CONT to confirm the selection of the newly created job. Now all required settings for a static survey are made. The Survey \ Begin panel looks as follows: Finally you have to select the antenna type and and antenna setup which you are using. Normally this will be AT502 on tripod (or AT501 on tripod in case of a SR510 sensor).
Measuring with the default configuration parameters, continued It is time to check again the icons on the top of the display: The Position Mode icon should be available, the Position Mode icon still indicates "moving" , the Number of visible satellites icon should display a number greater or at least 4, and the number of used satellites should be identical to the number of visible satellites.
Measuring with the default configuration parameters, continued Now use the height hook to determine the height of the antenna above the survey marker. Insert the height hook into the carrier and measure the height between the white mark at the bottom of the height hook and the survey marker. Enter this reading into the Ant Height field.
Measuring with the default configuration parameters, continued Datalogging should continue depending on your observation plan: a receiver used as reference has to run permanently until all rover site occupations are completed. If a unit is operated as a roving receiver the site occupation time depends mainly on the baseline length and your accuracy requirements. See General Guide to Static and Rapid Static for details.
Processing the data in the SKI-Pro software You can now switch off the receiver. Once power is off disconnect all cables and put all equipment back into the shipping case. In most cases, a short introductory course to the software will have been given by the local Leica Geosystems representative. You might now move to another site and repeat the procedure outlined in this chapter.
Processing the data in the SKI-Pro software, continued • Process the data Select the Data-Processing view of the project you want to process. The data which was previously reported appears on the screen in both a text and also graphical format. When the computation is finished activate the "Results" view of your project and examine the information which is made available, including the logfile. You must tell the program which station is the Reference and which points are Rover.
Care and Transport Transport Storage Cleaning and drying When dispatching the instrument, always use the complete original Leica Geosystems packaging (case and cardboard box). Temperature limits (-40°C to +70°C / -40°F to +158°F) Respect the temperature limits when storing the instrument, particularly in summer if the instrument is inside a vehicle.
