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
time interIVal of
subject
to
the
users’
requirement,
but
outlay,
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）
“h” is the inclined height that measure from point on the ground to the waterproof loop of
antenna.
R0
is the radius of antenna.
h0
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 (9pins 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.
