DOWNLOADING LOGGED DATAData logging involves the collection of GNSS measurement data over aperiod of time at a static point or points, and subsequent postprocessing ofthe information to accurately compute baseline information. Data loggingusing receivers requires access to suitable GNSS postprocessing softwaresuch as the CHC Geomatics Office (CGO) Software.The procedures of downloading logged data in the receiver are as follows:1. Switch on the receiver and connect it with a computer by USB Cable.After the successful connection, a removable disk named as the SerialNumber (SN) of the receiver will appear on the computer.2. Double click the removable disk and you will see the folder named as“repo”. Double click this folder, you will see 9 folders. The “push_log”folder is used to save the log files, and the other 8 folders representdifferent logging session and are used for store static data.3. Double click the folder that you has configured to store the static data,you will see the folder(s) created by the i70 system automatically andnamed by the date which is decide by GPS time when you start to logdata.4. Select the destination folder and double click it, and then two foldersnamed as different data format (hcn and rinex) will be displayed.5. Select the data format that you has configured to save the static data,you will find the static raw data.

2. Getting started with i70i70 GNSS Receiver User Guide Page 20Tip – For hcn files, the name of the file is represented as XXXXXXDDDNN,where XXXXXX is the SN of the receiver, DDD is day of year, and NN is therecording session.WARNING – The static data will be saved in the first logging session, the“record_1” folder, by default. Old files will be deleted if the storage space isfull. If you configure not to auto delete old files when the memory is low, thereceiver will stop data logging.

BASE STATION SETUP AND OPERATIONReal-Time Kinematic (RTK) operation provides centimeter-level precision byeliminating errors that are present in the GNSS system. For all RTKoperations, you require both a rover receiver and a source of correctionsfrom a base station or network of base stations.A base station consists of a receiver that is placed at a known point. Thereceiver tracks the same satellites that are being tracked by the roverreceiver simultaneously. Errors in the GNSS system are monitored at thebase station, and a series of position corrections are computed. Themessages are sent through a radio link to the rover receiver, where they areused to correct the real time positions of the rover.This chapter provides the information to help you identify good setuplocations, outlines basic precautions that you need to take to protect theequipment, and describes the conventional process to set up the basestation and the configuring procedure that required for transmittingcorrection data.4.1. BASE STATION SETUP GUIDELINESFor good performance, the following base station setup guidelines arerecommended:Place the GNSS receiver in a location on the worksite where equalrange in all directions provides full coverage of the site.Place the GNSS antenna in a location that has a clear line of sight to thesky in all directions. Do not place the antenna near vertical obstructionssuch as buildings, deep cuttings, site vehicles, towers, or tree canopy.The GNSS antenna must have a dear line of sight to the sky at all timesduring operation.Place the GNSS and radio antennas as high as practical. This minimizesmultipath from the surrounding area, and enables the radio tobroadcast to the maximum distance.Choose the most appropriate radio antenna for the size of the worksite.The higher the gain on the antenna, the longer the range.Make sure that the GNSS receiver does not lose power. To operatecontinuously for more than a few hours without loss of power at thebase station, provide external power. When you use an external powersupply, the integrated battery provides a backup power supply,enabling you to maintain continuous operation through a mains powerfailure.Do not locate a GNSS receiver, GNSS antenna, or radio antenna within400 meters (about 1,300 feet) of transmitters, such as a power radar or

4. Base station setup and operationi70 GNSS Receiver User Guide Page 29cellular communications tower.Do not set up the base station close to the sources of electromagneticinterference, include alternators and generators, electric motors,equipment with DC-to-AC converters, etc.Do not operate the receiver outside the specified operatingtemperature range -40°C to +60°C (-40°F to +140°F).Take reasonable care to keep the GNSS receiver equipment dry, whichcould prolong their life and reduce the effects of corrosion on ports andconnectors.4.2. OUTPUTTING CORRECTIONS USING INTERNAL RADIOMODEM4.2.1. BASE STATION SETUP1. Connect the radio antenna onto i70 receiver. Screw the receiver ontoextension pole.2. Screw the extension pole with auxiliary H.I. tool onto tribrach adaptor.3. Mount the tribrach onto the tripod.4. Insert the tribrach adaptor into the tribrach.5. Level and plumb the receiver over the known (control) point.6. Measure the height of the base station GNSS antenna by measuring theslant height from the known (control) point to the end of auxiliary H.I.tool.Note –After entered the vertical height from the known (control) point to thebottom of receiver that you calculated by adding the height of the extensionpole to the height from the known (control) point to the auxiliary H.I. tool,LandStar 7 will calculate the height to the Antenna Phase Center (APC)automatically.7. If required, connect the receiver to an external 12 V power supply.

ROVER STATION SETUP AND OPERATIONReal-Time Kinematic (RTK) operation provides centimeter-level precision byeliminating errors that are present in the GNSS system. For all RTKoperations, you require both a rover receiver and a source of correctionsfrom a base station or network of base stations.The second part of the RTK GNSS system is the rover receiver. The roverreceiver is moved between the points that require measurement or stakeout.The rover receiver is connected to a base station or to a source of RTKcorrections such as a CORS (Continuous Operational Reference System) orthe CHC APIS service. The connection is provided by:an integrated radioan integrated cellular modema cellular modem in the controllerThis chapter provides the information to help you identify good setuplocations, describes the conventional process to set up the rover station andthe configuring procedure that required for receiving correction data.5.1. ROVER STATION SETUP GUIDELINESFor good rover operation, observe the following setup guidelines:Place the GNSS antenna in a location that has a clear line of sight to thesky in all directions. Do not place the antenna near vertical obstructionssuch as buildings, deep cuttings, site vehicles, towers, or tree canopy.GNSS rovers and the base station receive the same satellite signalsfrom the same satellites. The system needs five common satellites toprovide RTK positioning.WARNING – Take care not to touch overhead power lines with the CHC i70GNSS receiver or the range pole when moving the equipment into position.Touching overhead power lines may cause electrocution, leading to seriousinjury.GNSS satellites are constantly moving. Because you cannot measure ata specific location now does not mean that you will not be able tomeasure there later, when satellite coverage at the location improves.To get a fixed position solution with centimeter precision, initialize theRTK rover receiver. For initialization to take place, the receiver musttrack at least five satellites that the base station is also tracking. In adual-satellite constellation operation, for example, GPS and GLONASS,the receiver must track at least six satellites.

5. Rover station setup and operationi70 GNSS Receiver User Guide Page 33To continue to survey at centimeter precisions, the rover mustcontinuously track at least four satellites that the base station is alsotracking. The radio link between the base and rover receivers must alsobe maintained.Loss of the satellite signals will result in a loss of centimeter positionprecision.5.2. ROVER STATION SETUP1. If required, connect the radio antenna onto i70 receiver.2. Screw the receiver on top of the range pole.3. Fix the controller bracket on the range pole.4. Fit the controller in the controller bracket.5. Level and plumb the receiver over the target measuring point.
