At this time, the static data have been stored in two files. Save data in internal storage GNSS static data are stored in “static”: in 1G massive memory. The effective storage space is 800M bytes. There are 3 files in total: log, gnss, rinex. log folder stores log information; gnss folder stores static data file whose format is *. GNS, rinex folder stores static data under standard format. You can use USB of Y –type data line to connect with the computer. Use USB to copy the static data to your computer. 31

Elementary Operation Note: when the storage space of receiver is less than 2M bytes, the data light (red light) will flash quickly and stop recording data. The current data file will not be covered. External SD card data storage The receiver shall support SD card data. SD card slot is installed under the battery. When the capacity of internal storage is not enough, the system will automatically store the static data into SD card. Before external data collection, it can use Y-type data line to connect the computer and receiver. Through receiver management software, manually set the storage location of static file in SD card/internal memory. The setting is successful after restarting the instrument. 32

Static Collection and Data Transmission Preface V60 receiver can be used in double-frequency static measurement. The setting method is double clicking Fn key, and then the voice broadcast will enter into work mode. Continue clicking Fn key and the work mode of voice broadcast is static mode when the satellite light and state light are on. Click power key to confirm. After successful setting, the red state light will flash one by several seconds (according to the sampling interval), one epoch will be collected by one flash. The static data can be stored in host or SD card. If the static data document shall be downloaded to computer, it shall use static post-processing software to process. Static Measurement 1. Setup the instrument in measurement point; align and level the instrument. 2. Measure height of the instrument for three times; the difference between two times shall not be more than 3mm; the average is regarded as the final height of instrument. Height of instrument refers to the distance between center of measurement point and measurement marker line of instrument. 3. Receiver parameters: ◇ Receiver radius 91mm ◇ The height from receiver bottom to phase center of antenna is 94.2mm 40

V60 GNSS RTK System Operation Instruction ◇ The height from measurement line of instrument to phase center of antenna is 39.3mm. Figure 4-1 4. Record the point name, instrument SN, height and initial observation time. 5. Start up and set the receiver as static mode. Flashing satellite light indicates that it is searching the satellite. If the satellite light turns to long-light state from flashing state, it indicates that the satellite is locked. The state light will be flashing according to sampling interval. One time of flashing indicates one epoch is collected. 6. Shut down after finishing measurement and record shutdown time. Measuring position of antenna height (lower edge of embossing position) 41

Static Collection and Data Transmission 7. Download and process data. Note: it is unable to move the base and change collection parameters during collection process. U Disk Data Download Receiver file management is stored by USB drive. It can be used upon inserting and download by dragging directly without download programs. It can only download static data and unable to write or read the receiver. The receiver can download USB drive data with Y-type data cable, one end is connected to computer USB and the other end is connected to eight-core socket on bottom of receiver. After connection, “static” disk and SD card will appear in computer. After opening the disk, it can copy the collected static file. Figure 4-2 The steps to modify point name and antenna height of downloaded static file are: 1. Choose *. GNS and double click the mouse 2. Pop up the dialogue of “file edit” to modify point name and input antenna height, and then click “ok” 42
