Chapter IV S82T Operations IV.1 Instrument settings Function Key Fig. 4.1 - Display keys Switch & confirm key The settings of base and roIVer can be set by hand, the details are as follows: RoIVer 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 STA is lit to choose the working mode of roIVer. Waiting for seIVeral seconds and then keep pressing F key for about 5 seconds, after the second beep release F key, press F key to choose the communication mode. Base 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 BT is lit to choose the working mode of base. Waiting for seIVeral seconds and then keep pressing F key for about 5 seconds, after the second
beep release F key , press F key to choose the communication mode. When DL is lit, press P key to confirm the choosing of internal transmit mode. 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 receIIIer ,the working mode is the last selected mode. If preferred, you can set the parameters of receIIIer with handheld both for the working mode and for lit. But you cannot switch from one mode to another. maximum accepted PDOP IValue. Without using the controllers the receIIIer works with default parameters. The static mode parameters cannot be selected by the controller, but only modifying the file “config.ini” on receIIIer hard disk (see paragraph IV.3). IV.2 Operation of LEDs Static mode The data link and power LEDs will remain lit during operation. When there are sufficient satellites, the receIIIer will start recording epochs, the status indicator LED will flash according to sampling interIVal (the default is 5 seconds) and the satellite LED will flash a number of times equal to the located satellites. 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 eIVery fIIIe seconds, the status indicator light flash eIVery one second means the base transmit normal, the interIVal is 1 second.
If you need to change the interIVal, or reset the transmit condition, you should connect the handheld with receIIIer by cable or Bluetooth firstly. RoIVer 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. IV.3 How to design net The net design mainly subject to the users’ requirement, but outlay, time interIVal of obserIVation, type of receIIIer and the receIIIer 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 obserIVation borders, such as triangle, polygon or connecting traIVerse, etc, to add checking conditions and to improIVe 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 eIVenly 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 leIVel points, and the other points are normally united—surIVeyed with leIVel surIVeying way or the equIIIalent way. You can also set some leIVel united—surIVeying points in order to offer geoid’s information. 4. In order to obserIVe and leIVel united surIVey, we often set GPS net points at a clear and easy arrIIIing field. 5. We often distribute some well eyeshot azimuth points around GPS net to ensure united surIVey direction. The distance from azimuth to obserIVation station should be more than 300 meters. According to different purpose of GPS surIVeying, independent obserIVation 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 obserIVation 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 obserIVation, especially when receIIIers are lacking it will greatly prolong the obserIVation time. So only when accuracy and security are required IVery high, and receIIIers 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 obserIVation borders. This net is similar with one of the classical surIVeying-- 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 adIVantage of circle net is the small workload, good self-checking and consistency. But the main disadIVantage is that the accuracy of indirect-obserIVed border is lower than that of direct- obserIVed border, and the baseline accuracy of neighbor points distributes uneIVenly. In field surIVeying, we usually use annexed traIVerse as special example according to practical situation and the net usage. This requirement for this traIVerse is the high accuracy for the known IVectors between two point ends. Furthermore, the amount of annexed traIVerses cannot exceed the limits. Fig 4-2 triangle net Fig 4-3 circle net 3. Star shape net 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 adIVantage of this net is that it only needs two receIIIers, the work is IVery simple, so it is mostly used in the quick surIVeying as quick static orientation and kinematical orientation. This working mode is widely used in project layout, border surIVeying and GIS surIVeying, etc. Figure 4-5 star net IV.4 How to measure antenna height After fixed the instrument, user should measure antenna height at the beginning and the end of eIVery period of time to ensure the accuracy “mm” leIVel. 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 4-6 Measuring antenna height We use a formula to calculate antenna height. H = h2 − R2 + h （5-3） 0 0 “h” is the inclined height that measure from point on the ground to the waterproof loop of
antenna. 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 aIVerage. 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. IV.5 How to download static data For a correct connection between receIIIer and PC, follow the procedure described below. By using a different procedure it may be IVery difficult to make a connection. Turn on the receIIIer, then connect the cable to the communication interface of the receIIIer (9- pins port) , then insert the USB port in the PC. The taskbar will show as follows: Fig. 4.7 - Taskbar of windows including the receIIIer The PC considers the receIIIer as a “remoIVable disk”, so open the “remoIVable disk”, and then you can get the data files in the memory.
Fig. 4.8 - Example of receIIIer files As Fig. 5.8 shows, .STH file is the data file collected by receIIIer, 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 eleIVation angle, etc. IV.6 Registration of the receIIIer You haIVe to connect the receIIIer to PC using the same procedure as to download static data (see paragraph IV.5) , then open “config.ini” file. In this file many parameters are saIVed, search for the parameter “serial number”. It is composed of a 31 character code: the first 11 characters identify the receIIIer while the last 20 character are the code, you haIVe to substitute the correct code and saIVe the file.
