After S8III and S7 Series, S8 gives new opportunities to exactly fit the Surveyor’s needs, featuring top performances with a budget price. Like the elder brother S8III, S8 is able to receive both of GPS signal frequencies and also satellite signals from GLONASS, GALILEO, COMPASS and SBAS, so we can correctly speak about a “GNSS receiver”.

Chapter I: A brief introduction of S8 III to-day work. STONEX provides two year of warranty to S8 receivers . It should be noted that high power ® signals from a nearby radio or radar transmitter can overwhelm the receiver circuits. Low power transmitter like those used in cell-phones do not normally interfere with receiver’s...
Chapter II: S8 III mainframe Chapter II: S8 mainframe II.1 The outlook of mainframe The mainframe has an almost cylindrical shape, with a base larger than the height. There are three parts: an upper cap, a rubber loop and the main structure. The upper cap protects the GNSS antenna placed inside.

Chapter IV: S8 III configuration Base mode The BASE, power led and selected datalink (UHF, GPRS/GSM or EXTERNAL) will keep lighted. When satellites fulfill the conditions, the base will enter into the transmit mode and start to send data through the datalink. The datalink green led flashing every one second means the base transmit normal.

Chapter IV: S8 III configuration IV.5 How to download static data For a correct connection between receiver and PC, follow the procedure described below. By using a different procedure it may be very difficult to make a connection. At first turn on the mainframe, then connect the cable to the communication interface of the receiver (7-pins Lemo port), then insert the USB port in the PC.
You can copy the original file to PC and if necessary modify the file names. As Fig. 4.7, for example, shows, .INI file is the configuration file stored in the memory of S8. You can open also the “CONFIG.INI” file as a simple text file and set some parameters of static mode: sampling frequency, minimum elevation angle, etc.

S8 after get PC connection. V.1 Start Stonex Assistant on your PC. Connect the S8 to the PC USB port using Lemo7 – USB/Serial cable. Switch on the receiver; automatically the program should search the COM port where the receiver is connected.
Page 33
When you find the right COM port, you should see the screen shown in Fig 5.3 that show you in the main window the system information. Fig. 5.3 – Information page of Stonex Assistant From the showed information you can understand about: the battery level, the firmware version of GNSS board, the antenna information, the firmware of radio and gprs internal device, the free disk space and the current working and datalink setting.
CONFIG .INI file and modifying it by hand in a text editor (not recommended). You can set the survey working mode (Static, Dynamic --> Base/Rover) and the kind of datalink (NETWORK, UHF, EXTERNAL, BLUETOOTH) of S8 (see the red rectangle in Fig. 5.4).
Chapter V: Stonex Assistant for S8 DefRadSettings Some definitions of working mode: Static: is the stand-alone station that collect raw observations and need a post-processing in office for getting accurate results. Base: is the fixed GPS station used to provide differential corrections to the mobile GPS receiver.
Page 36
Chapter V: Stonex Assistant for S8 DefRadSettings Fig. 5.5 – Static working mode From here you can control following data settings: Cut Angle : Define the minimum elevation of satellite to be collected in order to avoid noisy satellites (suggested value between 20° and 10°).
Chapter V: Stonex Assistant for S8 DefRadSettings Automatic Record : Start automatic GPS static survey after power on. For static survey this option strictly NEED to be enabled in Stonex Assistant. When the configuration is completed, click on button “Save” to update the Receiver configuration.
Elevation mask: Define the minimum elevation of used satellite to be collected in order to avoid noisy satellites (suggested value between 20° and 10°). Record Raw data: to record raw data inside memory of S8. Using Glonass: to enable/disable Glonass reception.
