1 X90 RTK Quick Start

This manual seeks for your convince of using X90 RTK. This Chapter offers a quick start by demonstrating the workflow with an example. Other applications of X90 RTK, refer to the following chapters.

1.1 Setting Up X90

1.1.1 X90 Receiver

The receiver has two parts: the Base featured by a serial number that ends with an even-number, and the Rover, with an odd number. There are two ports, as shown in the figure below. Connect the cables to the receiver as shown in the figure below and turn it on. You can set up the base when your receiver is tracking enough satellites. ·If you startup your base with the controller.

- Pull out the controller when the notice information is displayed then plug the data cable in the same port.

·If the receiver has a self-startup, you do not need to do anything.

1.1.2 Radio and Base

Connect the radio to the receiver (base) when the base is started. Signals are emitted by the radio with an interval of every 1 second, say, the red indicator lights up every 1-second and the voltage changes every 1 second too. You can check the working status of your radio with these features.

Fig.2. Radio Connections

1.1.3 Rover

- Connect every parts of the rover properly - Turn on the receiver. - Checking the radio receiving condition (by checking whether the radio indicator lights up

every second) - Set up the rover with the controller - When rover is fixed: Ready to work!

1.2 Preparation

You need to set up the control software before the survey to meet the surroundings. For details, are:

1.2.1 Coordinate System Management

On the controller: Configuration>Datum Manager (as the figure below shows)

Power

Base

Receive

Page 7: CHC X90En

HuaceNav

Fig.3. Datum Manage

To set up the Datum system (Coordinate System), you need to: ·Select an existing system and modify it (especially modify the Central Meridian. For standard Beijing-54 system, you must set the Central Meridians of 3-degree zone or 6-degree zone in line with entered known-points) ·Build a new system: Enter the ellipsoid parameters and some local coordinate parameters. Choose ‘Non’ on the base transfer, horizontal adjustment and vertical adjustment, because the last two will be filled with adjustment parameters derived from the point adjustment. Although not recommended, you can also enter the 7-parameter or 3-parameter on base transfer if you know them. Click ‘Ok’ to apply these parameters and have transferred result. A newly built project does not require a new point adjustment, since the parameters of the last project are used.

Notes: You must save your new project; otherwise, it will be covered by the next new file. It is recommended to select the Application for the Location

1.3 Setting up Base

The following steps are involved in this setup: Mounting the Base and radio antenna, connections among the radio antenna, base receiver, data transfer radio and batteries. Requirement: · The Base should stand on a wide-field place to have a good reception. · The Base should stand high to have a good condition of the UHF emission. If the rover is far

away, you need to add the radio antenna extender. You can put the base at either known-point or unknown-point. In addition, coordinates can be entered by the users or be directly loaded to the controller. ·At the known-point: You should startup the base with the known-point. You can also enter the

antenna height of the base as the preparation of the startup ·At the unknown-point: You need a re-checking step before hand. For details, see the following

sections.

1.4 Set up Base

1.4.1 Base Options

Select Configuration > Base Options (As shown below)

Page 10: CHC X90En

HuaceNav

10

Fig.9. Base Options ·Typical Broadcast Format is CMR (of course you can set it RTCA or RTCM). ·Survey Index could be a number from 1-99. Commonly, we use the default value for the Station

Index and Emission interval. ·The default Elevation Mask is 10. You can also modify it according to the satellite condition.

1.4.2 Start up Base Receiver

Select Survey>Start Base Receiver (‘Start Base Receiver’ would be in gray if the receiver is disconnected). The window below shows:

Fig.11. Start Base

We start the base with the entered single-positioning values. You can also select an existing known-point from the list (typically, the first startup is running with the single-positioning values followed by the point adjustment. Later works, if the transfer-parameters of the former works are used, would be started with the known-point, or with a preparation followed with an unknown-point). - Select Here then click Ok. The dialog-box below appears: - Click any button of Ok or Cancel to continue your work. However, Ok will save the current

settings for the next startup. The re-configuration becomes a must if the base is set at a new location. In addition, self-startup should be reset too.

Page 12: CHC X90En

HuaceNav

12

Fig. 12. Base Startup

- A ‘Setting up Succeeded!’ dialog-box appears

If you fail to start up the base: - A ‘Setting up failed!’ dialog-box appears. You need to re-start it then (This is mainly because

of a significant difference between the entered known-point and the single-positioning result due to the wrong setting of the central meridian or the non-standard coordinate.)

1.5 Setting up Rover

You can put your rover in your bag or mount it on the centering rod

1.6 Rover Configuration

Plug in the controller and set it up when you connect the rover to the GPS antenna(Base) and the radio antenna.

1.6.1 Rover Options

- Select Configuration>Rover options(As shown in the figure below)

Page 13: CHC X90En

HuaceNav

13

Fig.13. Rover Options

- Enter the parameters as the figure above shows. In this example, the station Index should be

any or the same value as that of one of the base. You can also enter any number among 1-99. The Antenna Height should be 2 meters. The Antenna Height Style should be Bottom of Antenna.

1.6.2 Rover Radio

To read and change the radio frequency: - set Configuration>Com Configuration and select COM1 for PDA com and COM2 for GPS com, as the figure below shows:

You can select a coordinate system and modify it or build your own one. For example, in some area there are only local systems, so you can modify an existing system (Especially modify the Central Meridian. For standard Beijing-54 system, you must set the Central Meridian of 3-degree zone and 6-degree zone according to the entered known-points). Then save it. To build a new system, set parameters such as semi-major axis and fattening, etc., as shown in the figure below. Normally, choose Beijing-54 as the local system. In addition, set the Base Transfer, Horizontal Adjustment and the Vertical Adjustment ‘Non’. The values derived from the point-adjustment will be automatically filled in later.

2.6.1 Start Base

Survey>Start Base, the figure below appears:

- You can enter the PointName to start the base. You can also select an existing point from the

List. Note: the difference between the entered/selected value and the value got by clicking ‘here’ should not exceed 500 meters. Otherwise, the base will not work properly and the application will tell ‘Base Config Failed’. - Click ‘Enter’. The dialog-box below appears (left), - Click ‘Ok’ on the dialog-box (left) then click ‘OK’ (Right).

Page 36: CHC X90En

HuaceNav

36

The alert ‘Base config succeeded’ tells that the configuration is done. Restart your station if ‘Base config failed’. Before clicking the Start Base, you need to check the settings of the Base Option and the Base Radio. The purpose of starting the base-station is to mount the carrier phase value and the coordinate of the starting point on radio carrier and emit it by radio.

2.6.2 Start Rover

Survey>Start Rover:

Fig.61. Start Rover Successfully Before clicking Start Rover, you need to check the settings of the Rover Option and the Rover Radio. Initialization starts with the displayed information sequences as: No data>Initialize>Float>Fixed. The next step could be carried out only when ‘Fixed’ is displayed. Otherwise, the precision would be relatively low. A good ‘fixed’ condition can give you a millimeter–precise mean-square-error. The rover collects carrier phase, meanwhile, it receives signals from the base radio and have them demodulated to get carrier phase of the base. The purpose of starting rover: Using OTF technology, the rover calculates the ambiguity with the carrier phases of both base and rover and derives rover position at the centimeter-precision. The point of this method consists in having (initialization) and holding initial ambiguity. Therefore, besides for the sufficient amount and reasonable distribution of the satellites, the RTK Surveys also require good communication between the base and rover.

by time. Then click ‘Cal’ (calculate)then click ‘OK’, two dialog-boxes will appear, click ‘Yes’ to

apply the calibrated datum to current project.

If you don’t want to bring a point into calibration, you should edit the point (select the point and

click ‘Edit’) and select ‘Off’ for ‘Use’. You can also delete this point and click ‘Cal’ to continue.

The function of ‘Site calibration’ is to get the converting parameters from WGS84 to the local

datum. If you select ‘Yes’ for all the dialog-boxes when ‘site calibration’ is done, the parameters

will be stored in ‘Current datum Parameters’, details see section 2.3.5 .

2.6.4 Measurement Point

3 Often Used Issues

3.1 Local Coordinate Survey

3.1.1 Overview

It is well acknowledged that the GPS works under the WGS84 system and what the RTK Survey obtains is the position increment (⊿x ⊿y ⊿z) between the rover and the base under such system. While what the users want is, the state coordinate system (such Beijing 54 and China 80) or the plane coordinates and level heights in the local system. Therefore, it is necessary to have the Surveyd WGS84 coordinates transferred into the state/local system4 by running the point adjustment. For static Survey, the point adjustment is carried out using the cooperated Survey with the known local controlling points. In addition, for RTK Survey, it wants beforehand the transfer-parameter that often refers to the 7-parameters, the 4- parameters, the Northern slope and the Eastern slope. However, in a relatively small survey area, you only need to take the 4-parameters and the Northern/Eastern slopes into account. There are two ways to get the transfer parameters: the RTK adjustment or entering them (derived from network adjustment or transfer parameter generating application) into the controller according to the post processing results.

The 4-Parameter is represented as (⊿x ⊿y k α) refers to a pair of moving value, a scale and a rotation angle. As we all know, low precision under the WGS84 (5 meter - 15 meter) actually cannot meet the requirement of Survey. To get a better precision, you can re-enter the WGS84 coordinates into the

Page 54: CHC X90En

HuaceNav

54

controller when the WGS84 precision between a pair of bases is relatively desirable. However, it would be more convenient to enter an approximate WGS84 coordinate in the base followed with a rover-derived (⊿x ⊿y); no extra work would be involved.

3.1.2 Base Self-starting

The Base Self-starting refers to: without using the controller, the base starts to emit differential data automatically as soon as the satellites signals are received. You can set up the self-start function by following steps:

- Connect the receiver to the PC, turn on your receiver and double-click , the figure below shows:

- Select Management>Receiver Settings, the interface below appears:

Page 55: CHC X90En

- As Fig.91 shows, the Self-start parameter is Never. Click the Self-start button, the alert below appears:

- Select ‘Ok’, then Never becomes Self-start, as shown in the figure below:

- The Self-start setting up is done now, click ‘Quit’ to finish.

3.1.3 Point Adjustment

- Survey>Site Calibration. The window below(Right) - - Click ‘Add’ to access the window below(Left):

·Select the entered local coordinates in the Grid Points. All displayed points are under local

coordinate system. ·Select the entered or Surveyd WGS84 coordinates in the GPS Point. All displayed points are
