Chapter I: A brief introduction of S82V
Chapter I : A brief introduction of S82V The SOUTH S82V is a RTK GNSS receiver, built for precision, reliability and user friendliness. S82V is able to receive GPS signals, and also satellite signals from GLONASS and GALILEO. The S82V main receiver unit is integrated with GNSS antenna interface, GNSS module, UHF radio interface, receiving radio antenna, GSM/GPRS modem and Bluetooth device to facilitate working convenience for the user. The S82V receiver is lightweight and sturdy, and designed for rugged usage. The receiver housing is waterproof and dustproof, and built with superior material to withstand long lasting operation in the field. Advanced data-transfer radio technology is used in the S82V: the bit error rate (BER) is 10-7 and the radio collision problem is significantly reduced. The UHF antenna is designed both to reduce interference and for compactness. At the same time, S82V has a GPRS/GSM module which supports different core RTK technologies (VRS, FKP, etc.). This allows the SOUTH S82V receiver to cater for different surveying applications. When configured as a rover, it can be used as a static double frequency receiver or in a RTK configuration, where differential corrections are received by CORS via GSM/GPRS data modem (maximum range 70 km) or by another S82V receiver acting as base, linked by GSM/GPRS data modem or UHF radio modem. The S82V in base configuration can employ internal radio or external radio in addition to using a GPRS set up for communication with the rovers and/or CORS station. The embedded receiver firmware can customize different RTK software for different applications. The data transfer process is a very convenient one. You could contact

Chapter III: S82V external radio
Chapter III : S82V external radio III.1 Introduction to radios Pacific Crest is the leading provider of high-performance data links for the Geomatics industry based on the acceptance of its communications protocols as the standard for RTK surveying. The external radios
are high speed wireless semi-manual data transfer radios whose baud
rate can reach 19200bps, which is used in S82V GNSS RTK GPS system. These radios adopt GMSK adjust mode, and they have a very low bit error rate (BER). They adopt a transparent mode to transfer data to the RTK GPS system. The data transfer interface of radios is the standard RS-232 interface (serial port); it can do data transferring with any terminal equipment which has RS-232. They adopt advanced wireless booting technology, data processing technology and base band processing technology which ensures a long operational life. There are three frequency ranges for PDL radios, 410-430MHZ, 430-450MHZ and 450-470MHZ. The eight radio channels and relative frequency are listed in the following table:

Chapter III: S82V external radio
Note: it’s better to use the low power option. The high power option will consume twice the power
III.3 Notices for PDL The specification of power supply is as follows: PDL radio power input is 9-16V (typical is 13.8V), the RF power is 35W, the current is lower than 7.1A (when power is 13.8V) Before switching on the PDL radio, you should check whether the anode and cathode are connected correctly, if they are reversed, it will damage the radio. Using a 35W radio will add the consumption of battery, usually the 15W is enough, if the interference is strong, then you can select the 35W.

Static mode Keep pressing P+F keys and wait for six lights flashing at the same time, then press F key to choose the working mode, press P key when the BAT is lit to choose the static mode. When you next turn on the receiver ,the working mode is the last selected mode. If preferred, you can set the parameters of receiver with handheld both for the working mode and for lit. But you cannot switch from one mode to another. For instance the rover parameters includes: sampling interval, mask angle, antenna height, maximum accepted PDOP value. Without using the controllers the receiver works with default parameters. The static mode parameters cannot be selected by the controller, but only modifying the file “config.ini” on receiver hard disk (see paragraph V.4).
V.3
Operation of LEDs Static mode
The data link and power LEDs will remain lit during operation. When there are sufficient satellites, the receiver will start recording epochs, the status indicator LED will flash according to sampling interval (the default is 5 seconds) and the satellite LED will flash a number of times equal to the located satellites.
29
Chapter V: S82V Operations
Base mode After setting up the mode, power on the mainframe, the base will enter the transmit mode 1.PDOP<2.5; 2.the satellite amount>8 and PDOP<4.5, the base will enter the transmit status, the data link flash twice every five seconds, the status indicator light flash every one second means the base transmit normal, the interval is 1 second. If you need to change the interval, or reset the transmit condition, you should connect the handheld with receiver by cable or Bluetooth firstly. Rover mode Bluetooth and power LED will remain lit during operation. The satellite LED will blink according to the number of satellites as described for static mode. Data link LED will blink with the frequency of 1 second, while Status light will blink with a frequency of about 5 seconds.
V.4
How to design net
The net design mainly subject to the users’ requirement, but outlay, time interval of observation, type of receiver and the receiver amount, etc also relate to the net design. In order to satisfy the users’ requirement, we should keep the principle as follows: 1. GPS net normally forms closed graph by independent observation borders, such as triangle, polygon or connecting traverse, etc, to add checking conditions and to improve the net consistency. 2. When designing the net, the net point should be superposition with the original ground net points. The superposition points are generally no less than three and distribute evenly on the net in order to ensure the changing parameters between GPS net and local net. 3. GPS net point should be superposition with the level points, and the other points are normally united—surveyed with level surveying way or the equivalent way. You can also set some level united—surveying points in order to offer geoid’s information. 4. In order to observe and level united survey, we often set GPS net points at a clear and easy arriving field. 5. We often distribute some well eyeshot azimuth points around GPS net to ensure united survey direction. The distance from azimuth to observation station should be more than 300 meters.
30
Chapter V: S82V Operations
According to different purpose of GPS surveying, independent observation borders of GPS net should compose definite geometry graph. The basic graphs are as follows: 1.
Triangle net
The triangle in GPS net is composed of independent observation borders, it has strong geometry structure and well self-checking ability, it can also find out the coarse difference of result and to share the difference to each baseline with adjustment. But this net need a lot of observation, especially when receivers are lacking it will greatly prolong the observation time. So only when accuracy and security are required very high, and receivers are more than three, we can use this graph, see fig 5-3. 2. Circle net Circle net is composed of many loops which are formed of many independent observation borders. This net is similar with one of the classical surveying-- lead net. Its structure is a little worse than triangle net. The amount of baselines in closed loop decides the self--checking ability and consistency. General speaking, the amount of baselines has such limit as follows: The advantage of circle net is the small workload, good self-checking and consistency. But the main disadvantage is that the accuracy of indirect-observed border is lower than that of directobserved border, and the baseline accuracy of neighbor points distributes unevenly. In field surveying, we usually use annexed traverse as special example according to practical situation and the net usage. This requirement for this traverse is the high accuracy for the known vectors between two point ends. Furthermore, the amount of annexed traverses cannot exceed the limits.
Fig 5-3 triangle net
Fig 5-4 circle net
3. Star shape net
31
Chapter V: S82V Operations
Star net has simple geometry graph, but the baselines of it mostly don’t compose a closed graph, so it has a bad checking ability and consistency. The advantage of this net is that it only needs two receivers, the work is very simple, so it is mostly used in the quick surveying as quick static orientation and kinematical orientation. This working mode is widely used in project layout, border surveying and GIS surveying, etc.
Figure 5-5 star net
V.5
How to measure antenna height
After fixed the instrument, user should measure antenna height at the beginning and the end of every period of time to ensure the accuracy “mm” level. We usually measure from the center point on the ground to the center waterproof loop of antenna. That is an inclined height. Please refer to fig 5-6.
Fig 5-6 Measuring antenna height We use a formula to calculate antenna height. H h 2 R02 h0
(5-3)
“h” is the inclined height that measure from point on the ground to the waterproof loop of antenna.
32
Chapter V: S82V Operations
R0 is the radius of antenna.
h 0 is the distance from antenna phase center to the middle of antenna. H is the calculation result. We usually measure antenna height twice and adopt the average. Attention: We input the inclined height as the antenna height, which is the inclined distance from point on the ground to the waterproof loop of antenna.
V.6
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. Turn on the receiver, then connect the cable to the communication interface of the receiver (9pins port) , then insert the USB port in the PC. The taskbar will show as follows:
Fig. 5.7 - Taskbar of windows including the receiver
The PC considers the receiver as a “removable disk”, so open the “removable disk”, and then you can get the data files in the memory.
33
Chapter V: S82V Operations
Fig. 5.8 - Example of receiver files
As Fig. 5.8 shows, .STH file is the data file collected by receiver, the modified time is the time of the last epoch collected. You can copy the original file to PC and if necessary modify the file names. You can see also the config.ini files. You can open it as a simple text file and set some parameters of static mode: sampling frequency, minimum elevation angle, etc.
V.7
Registration of the receiver
You have to connect the receiver to PC using the same procedure as to download static data (see paragraph V.6) , then open “config.ini” file. In this file many parameters are saved, search for the parameter “serial number”. It is composed of a 31 character code: the first 11 characters identify the receiver while the last 20 character are the code, you have to substitute the correct code and save the file.
34
Chapter V: S82V Operations
Appendix 1: Frequently Asked Questions 1. The receiver is set in static mode but it does not save data even if more than three satellites are locked. The three red lights are blinking. Solution: the internal memory of receiver is full, please delete some files. 2. The external and built-in power lights are blinking and I do not succeed in receiving differential corrections. Solution: The serial code is expired, please contact SOUTH for a new code. 3. I do not succeed in connecting handheld and receiver by Bluetooth. Solution: you are in static mode and Bluetooth is disabled, please switch mode. If you are in rover or base mode and Bluetooth still does not work, please perform a receiver self-check. If the problem persists please check config.ini, it may be in a wrong format, please contact SOUTH for a new config.ini file. 4. The receiver is set in rover mode and GSM data link, the SIM card is placed in its slot under the battery. However I do not succeed in reading the SIM card. Solution: Every SIM have its PIN number, it must be disable. Moreover check on a cell-phone that there is enough money on SIM for connecting to the internet.
