JIYI J-RTK

JIYI J-RTK

JIYI J-RTK is a new generation of high-precision navigation and positioning system developed by Polar Wing. It improves the three-dimensional positioning accuracy from meters to centimeters through real-time dynamic difference technology. Accurate and reliable positioning solution. JIYI J-RTK achieves similar performance at lower price; It is a very cost-effective centimeter-level positioning module. It is an ideal choice for UAV aerial performance, agricultural application, high-precision takeoff and landing, ship takeoff and landing and other applications requiring real-time high-precision navigation.

High-precision positioning receiver

The is a precise positioning service system based on satellite positioning system (compatible with Beidou, GPS, GLONASS, Galileo). It uses ground-based differential enhanced base stations and self-developed positioning algorithms to perform big data calculations through Internet technology. It consists of multiple RTK base stations, A J-RTK cloud network provides precise positioning services for users in the coverage area of the J-RTK network.

Features

1. Centimeter-level positioning accuracy, powerful multipath effect and interference suppression technology;

2. High-precision orientation of dual antennas, strong anti-magnetic interference;

3. High sensitivity, stability and reliability.

Radio Base Station

Suitable working environment

1. Tasks requiring high-precision positioning;
2. In foreign countries, only base stations can be used to use sky terminal RTK;
3. RTK base stations are required in areas where the Qian xun network does not exist;
4. Coverage: About 2km;

Use process

1. Set up a base station in a high and open environment;
2. The antenna of the base station should also be as high as possible to better receive satellite signals and send positioning data to the aircraft;
3. Turn on the device switch and turn on the radio switch at the same time;
4. Wait for 3-5 minutes, the RTK light will flash quickly, and the radio switch will also flash slowly;
5. After the RTK light and radio switch light flash stably, it indicates that the BTS has been positioned;
6. After the base station is located, the aircraft with radio RTK can be used for operational flight;

Network Base Station

1. Tasks requiring high-precision positioning;
2. Areas with poor Qianxun location information but stable mobile network data in China;
3. When the domestic sky terminal RTK or RTK Dotter is in arrears, it can be used with the network base station;
4. Coverage: about 20km；

Note:

1. When using the network base station function, the flight defense app should always have network data;
2. The network base station needs to insert a mobile traffic card. The card insertion method is shown in the following figure;

Device management

When using the network base station function, the SN numbers of the base station and other RTK devices must be added to the app. Only after the SN numbers of other devices are added to the network base station white list can the positioning information of this base station be used normally.

White list adding steps

Open the flight defense manager app, “equipment management” – “RTK base station”;

Click “+” in the upper right corner to add the BTS equipment, enter the SN number and security code of the BTS, and then click “submit”;

After successful submission, the BTS list is returned;

After selecting the online BTS equipment, you can view the details of the BTS (SN number, erection address and white list);

After clicking “white list”, click “+” in the upper right corner to add other RTK devices, such as sky terminal RTK and RTK Dotter. Enter the SN number of RTK and click “submit”;

After the submission is successful, you can view the RTK device in the white list, which means that the RTK device can use the location information of the network base station;

After the RTK white list is successfully added, you can connect the sky terminal RTK or RTK Dotter for normal use (as shown in the following figure);

Network base station usage process

1. Set up a base station in a high and open environment;
2. The antenna of the base station should also be as high as possible to better receive satellite signals and send positioning data to other equipment;
3. Turn on the BTS equipment switch, observe that the net and RTK signal lights flash, and wait for positioning;
4. Wait for about 1 minute, and the net light will start flashing yellow, indicating that the network connection is normal;
5. Wait for 2–5 minutes, and the RTK light will flash quickly, indicating that the BTS has been positioned;
6. After the RTK light and net light flicker stably, you can use the sky end RTK or RTK Dotter to spot;
