Getting Started with X900U+ completely before using it for the first time. To charge the battery, first, remove the battery from the receiver, and then place it in the battery charger, which is connected to AC power. WARNING - Charge and use the rechargeable Lithium-ion battery only in strict accordance with the instructions.
Getting Started with X900U+ (2) If battery fluid gets into user’s eyes, immediately rinses user’s eyes with clean water and seek medical attention. Please do not rub user’s eyes! (3) If battery fluid gets on user’s skin or clothing, immediately wash them off under running water.

Getting Started with X900U+ 2.5 Connecting to Controller with LandStar 7 This section uses Smartphone as the example to show how to connect the receiver to the controller using LandStar 7 via Bluetooth. Turn on the receiver → Launch LandStar 7 → press config on the bottom of the screen →...
Getting Started with X900U+ (4) After the processing completes, please close the uploader, and then power off and power on the receiver again. (5) Now, the whole update has been finished successfully. 2.7 Downloading Logged Data Data logging involves the collection of GNSS measurement data over a period at a static point or points, and subsequent post-processing of the information to accurately compute baseline information.

Getting Started with X900U+ Notes: For hcn files, the name of the file is represented as XXXXXXDDDNN, where XXXXXX is the SN of the receiver, DDD is day of year, and NN is the recording session. WARNING – The static data will be saved in the first logging session, the “record_1”...
The system needs at least five common satellites to provide RTK positioning. WARNING – Do not touch overhead power lines with the CHC X900U+ GNSS receiver or the range pole when moving the equipment into position. Touching overhead power lines may cause electrocution, leading to serious injury.
3.2 Configuring the Rover Station via LandStar 7 Software 3.2.1 Receiving Static Data (1) Power on the receiver. (2) Run LandStar 7 on the controller → create a new project or open an existing project → establish the connection with the receiver via Bluetooth. (3) On the Static Setting screen, set parameters as need and then click Set to finish.
4 Survey with LandStar 7 Software The CHC LandStar 7 Software (“LandStar 7”) is a field survey software which developed based on more than ten years of development experience of CHC and feedback of surveyors from different fields of application. LandStar 7 provides with a complete set of features for any survey projects, including data collection, stakeout, COGO (Coordinate Geometry) function, and more, which makes this software an ideal option for everyday field work.

(2) Tap add button in the lower left corner of Points screen, and then configure the related parameters of the new point as follows: Name: Enter the point name. Code: Enter the code of the point, if required. Coordinate Format: Select the coordination format from the dropdown list. There are five available options: Local N/E/H, Local Lat/Lon/H, Local X/Y/Z;...
WGS84 Lat/Lon/H, WGS84 X/Y/Z. Coordinate: depend on the coordinate format user choose. (3) Tap ok button at the bottom of New point screen to save the point. 4.3 Measure Points Note: To ensure the accuracy of the coordinates measured; please perform measurements after the rover receiver receives correction data (with correction LED flashes once per second) and gets a fixed solution.

Notes: • General speaking, if a three- or seven-parameter datum transformation has been configured for the project, users can skip the site calibration and the coordinates measured will be transformed automatically into local grid coordinates. • If a projection and datum transformation have already been specified, users can reduce any discrepancies between the WGS-84 coordinates and the local grid coordinates by performing a site calibration.

4.6 Base Shift Typically, the Real-time kinematic (RTK) operation requires a data link to send observations or corrections from the base station to the rover, and then the rover will calculate its position in real time. Within a project, when the base receiver is restarted or moved, the base coordinated system will shift each time the position of the base station is changed.
