Notice 1. If users use Bluetooth connection, users must break it. Otherwise, it will
bind the station by default after rebooting the base station, which will result in that the base
fails to transmit differential signals.
2.If the base is set to Auto Base, it will start working wherever connected to radio after the
boot without any other setting, which is convenient and efficient.
3.3 DL5-C Radio Setting
When operating in radio mode, users can use the on-off button on the radio panel to turn on
the radio, use channel switch button and pousersr switch button to set the pousersr and
frequency.
20
Notes: Each channel corresponds to only one frequency. Users can set the frequency of

Use [Pousersr switch] button to set the radio pousersr. When [Red-High] light is on, the
default pousersr is 20W (can be set to 28W via write frequency software).
When [Blue-Low] light is on, the default pousersr is 5W (can be set to 10W via write
frequency software). The pousersr is related to operating distance. In general, it is set to
[Blue-Low] and the default pousersr is 5W. The operating distance in open areas can be
arrived at 10 kilometers. The higher the pousersr is, the longer the operating distance will be.
Housersver, working in long time and high pousersr will lead to the radio’s overheating
which will reduce the radio’s service life. Therefore, it’s recommended to use the pousersr
as low as possible.

four or more than four control points are involved in the vertical Point Calibration, there will
be vertical residual error which is usually within 0.02m.
49
2. After point calibration, users can start measuring directly.
3. Control points involved in point calibration should be distributed reasonably and avoid
linear distribution. It will be better if those points cover the whole survey area, avoiding short
sides controlling long sides.
6.6 Base Shift
It takes several days or even longer time to measure or stake out in each survey area. In
order to avoid repeated point calibration or troublesomely erecting the base on the same
known point everyday, users can do Base Shift before starting surveying everyday( at this
point, the base can be erected at random or set to Auto Base, but the rover’s operation is a
process that is finding a measured point and moving to that).
The specific explanation is shown as follows:
After users erect bases repeatedly, the software will orderly name the bases Base 1, Base
2,Base 3 and so on
The rover’s coordinates are based on the base’s original coordinates which will change as a
result of moving the base, so users need to reset local coordinates every time moving the
base.
Open LandStar6, in the main menu, click [Survey]→[Base Shift] to enter Base Shift
interface. It is necessary to shift base when the base moves or needs restarting because of
erecting on an unknown point. Users need to find a known point and measure its
coordinates to calculate the shift data. Then apply the shift data and make it function on all
survey points in current coordinate system. Make sure the two bases’ coordinates have the
same reference coordinate system.
Enter Base Shift interface, select known points from [Known Point] Library, click [GNSS
Point] Library to select the same point surveyed just now. The software will calculate the
50
shift data. Click [Yes ], the software will prompt: Base base_1 and related points
translated, open the lib? Click [Yes] to open the point library, and the shift data will be
applied to all survey points on the base, and plane coordinates will be changed.
6.7 Data Export
Open LandStar6, in the main menu, click [Project]→[Export], according to the required
data format, export data. Then connect PDA with PC( users need to install Microsoft sync
software or USB Drive first), click [Mobile]→[My Windows Mobile Device]→[My
