What are high-precision positioning services? What are they?

The high-precision positioning service provided by Chance Position is high-precision positioning correction service, which is to take your inaccurate positioning accuracy (5-10 meters of ordinary GPS positioning) and realize a significant increase in accuracy through the differential data broadcasted by Chance Position platform and the support of third-party hardware vendors' differential algorithm chips. Chance Position currently has a variety of related products at sub-meter, centimeter and static meter levels.

Sub-meter and centimeter level are real-time services, which are commonly used in high-precision positioning of wearable devices, in-vehicle high-precision positioning, instrument measurement, geographic information collection, precision agriculture, drone application, autonomous driving, driving test and training, and other scenarios with high accuracy requirements.

Static millimeter-level is a post-processing service, which returns millimeter-level results after computing on Chance platform through the accumulation of a large amount of observation data, and is commonly used in scenes with extremely high precision requirements, such as monitoring of dangerous houses and monitoring of landslides in dams.

Developers or consumers can choose appropriate high-precision positioning products and services according to application scenarios and needs.

What is the principle of FindM Pro and other services?

Terminals with high-precision positioning function receive satellite signals to obtain the approximate position data (not precise) of the location, and then upload this position data (GGA) to ChanceM platform through the Internet, together with the Ntrip protocol parameters.

After obtaining your data, Thousandsearch platform will dial the satellite differential correction data of your location through the Internet.

At this time, you need to use the differential calculation function of the device, combining the original carrier observation value of the terminal and the differential correction data sent by Thousandsearch, to carry out the calculation, to realize the positioning correction, and to obtain the high-precision position coordinates.

What are the requirements before use?

1. The device has a chip that supports differential correction and can solve the differential data broadcasted by Thousand Seek position;

2. Internet connection;

3. Outdoor open area to ensure the reception of satellite signals;

4. Within the service coverage area;

5. Hardware devices need to support relevant protocols and data broadcasting formats;

  1.FindCM, terminal hardware needs to support Ntrip Client protocol, differential data broadcast in RTCM3.2 format;

 2. FindMM, the terminal hardware must support Ntrip Server protocol, differential data broadcast in RTCM3.2 format;

 3.FindM Pro, the terminal hardware must support Ntrip Client protocol, differential data broadcast in RTCM3.2 format;

6. If the service is requested by differential account and password, please make sure that the GGA is uploaded and the relevant parameters of Ntrip protocol are filled in correctly;
