2A33X-Q300GNSS Receiver

Qianxun SI RTK Quick Start 【 Product Introduction 】 The Qianxun SI Survey RTK product suite consists of a Qianxun SI Survey RTK Receiver and related accessories. Note: This instruction is applicable to Q300 and Q600 products. Indicator Description: Indicator Light Satellite Status Blue light flashes when searching for stars, always on after finishing positioning Power Status Power light blinks when the power is <10% Data Status Green light blinks 1s for differential data in dynamic RTK mode Static mode blinks at sampling frequency interval Key Description: Key Startup & Shutdown Press and hold for 3s to turn on, long press for 3s to turn off Inquiry Click the key to check the battery status Mode Switch Double-click the button to switch modes and click to confirm [ Turn on the device ] It is suggested to charge the device for the first time before using it. Turn on the RTK host and controller → Press the "APP" button in the controller to start the measurement software. The first time you use it, a privacy agreement will pop up, accept it and use it. [Connecting Instruments] Click the device icon button in the upper right corner of the app to enter the device connection interface. In the device connection interface, you can choose to conn ect the device after using Wi-Fi search, as in Figure 1. Note: Qianxun SI survey RTK products start with "QX" by default, such as QX21000034 【 Activation 】 Host Registration When you use the device for the first time, you need to use the registration code to open the authorization to use the device. Please apply for the registration code from the distributor who purchased the device. Registration method: App upper right corner device icon → click [Device] in the device information after the [Regist] button can be entered, prompt Service Activation If you have purchased a star-based service, you need to use the authorization code to open it in order to achieve high-precision positioning operation without network on a single device. In the device information, you can click the [Regist] button after [XStar] to activate the star-based service, please consult the manufacturer's technical staff for service coverage. Star- based service needs to update the key file once every six months, and you can select the locally imported key file by [Select file]. [New Project] When you enter the App, Qianxun SI has automatically created a project for you. The default project name is controller system time, the coordinate system is WGS84, the projection is horizontal axis Mokato If necessary, you can go to the left menu bar to create a new project or modify the project information and the required coordinate system parameters, as in Figure-2. Figure-2 [Data Import] In the point library, you can select the required data format and file to import data, as shown in Figure 3- 6. [Work Mode Configuration] The first time you turn on the machine, it will automatically enable "Radio", you can directly carry out survey operations. If there is no network on site or you have other needs, you can configure as follows: Enter the device configuration interface through the left menu bar → [Device Config] You can configure rover station, base station and static station as required. Create Rover Station Mode Click the [Create] button, [Type] select [Rover], and choose the data chain mode. Radio: Some models have radio function, at this time you need another RTK to be the Base station and broadcast differential data to the mobile station via radio for measurement operation. This mode is suitable for all outdoor work scenarios. Star -based: Some models are equipped with star-based function. Star-based service does not depend on network and does not need to set up a reference station, and can achieve centimeter- level positioning by a single machine. The satellite-based service needs to be opened according to the area, and high-precision operation can be realized within the coverage of the satellite-based, please consult customer service or authorized distributors for details. Create Base Station Mode Some models have base station function. Click [Create] button, [Type] select [Base], configure radio related parameters and click OK to finish the configuration. If there is a known point, you can select [Known Point] mode, enter the ground point coordinates and antenna slope height to start, as in Figure- 8. Create Static Station Mode Static station mode is used for control network deployment and control point encryption. Click the [Create] button, select [Static] for [Type], and configure the relevant parameters to complete the configuration. The default sample interval is 10s and the default file format is RINEX3.02, as shown in Figure 9. 【 Survey】 Menu bar on the left → [Survey], the main interface switches to point measurement mode. In the point measurement mode, you can select the first configuration button in the right toolbar of the interface to configure the required measurement parameters, as shown in Figure-10. In the main interface, you can switch the type of measurement points ( Control Point, Continuous Point, Rapid Point, Topographic Point, Eccentric Point), enter the required number of observation points and other parameters, and then click [Start survey] to collect the required type of points, as shown in Figure- 11. [Parameter Calculation] Point Correction The first time you go to a survey area, you need to do point correction if you want the measured point to match the known point coordinates. If you are using Qianxun SI network operation mode and your project coordinates match the CGCS2000 coordinates broadcasted by Qianxun SI, you can skip this step. The left menu bar → [CRS] → [Site Calib], you can enter the point correction parameter calculation interface, as in Figure- 12. Select the plane coordinates of known points in N pairs of survey area and the latitude and longitude coordinates under the ellipsoid corresponding to known points, click [Calculate] to solve the plane …

RF EXPOSURE EVALUATION 5.1 Applicable Standard FCC §15.247 (i) Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission's guidelines. See §1.1307(b)(1) of this chapter. 5.2 Procedure According to §1.1307(b)(3)(i) (C) Or using Table 1 and the minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. For the exemption in Table 1 to apply, R must be at least λ/2π, where λ is the free-space operating wavelength in meters. If the ERP of a single RF source is not easily obtained, then the available maximum time-averaged power may be used in lieu of ERP if the physical dimensions of the radiating structure(s) do not exceed the electrical length of λ/4 or if the antenna gain is less than that of a half-wave dipole (1.64 linear value).
