BroadGNSS Technology Co., Ltd. is a national high-tech enterprise focused on satellite navigation and positioning solutions and product development. The company has introduced a new type of RAC (Realtime Array Calibration) high-precision satellite positioning receiver to the market. This receiver features the use of standard civilian single-frequency signals (GPS L1 or BDS B1) without relying on any differential technology (or auxiliary technologies like inertial navigation), achieving positioning accuracy better than sub-meter and decimeter levels. The application of this technology eliminates the dependence on ground-based augmentation networks while significantly reducing costs, accelerating the widespread adoption of high-precision satellite positioning.
  BroadGNSS's IoV system offers basic positioning features, vehicle monitoring, alarm management, system monitoring, and various auxiliary driving functions to assist drivers in responding to unexpected situations. These functions significantly enhance driving safety, especially in emergency response vehicles (such as ambulances and fire trucks) and special operation vehicles, providing immense practical value. The system is suitable for a variety of transportation modes and industries, including buses, official vehicles, motorcycles, electric vehicles, forklifts, agricultural machinery, construction machinery, port container trucks, and more. Through the integration of hardware and platform, BroadGNSS's RAC IoV products enable efficient remote operation and management.   
he Eight Major Pain Points of RTK Ground-Based Augmentation Mode in the Automotive Field
1. Terminal hardware, differential technology, and components were originally used in the surveying industry, resulting in high hardware costs.
2. Service fees must be paid to obtain differential correction data. 3. Communication data fees are required for transmission between the user terminal and the augmentation system, and these fees are paid to the 4G telecom operator. 4. Data confidentiality issues: the ground-based augmentation network involves bidirectional data, and the user's location data is automatically collected by the operator without compensation. 5. Limited usage range: it only works within the coverage area of differential stations. In reality, the range with guaranteed usable signals is still very limited. 6. Due to the complexity of the technology, it is difficult to collect evidence for legal protection. After an accident, it is hard to determine responsibility among the satellite network, ground-based augmentation network, 5G/4G operators, and terminal equipment suppliers. 7. Low availability, with poor data integrity. 8. High-precision RTK antennas are too large and thick to be installed on mass-produced vehicles. RAC satellite positioning technology can address the following eight major pain points
1. The user purchases terminal hardware at a low price, with low BOM hardware costs.
2. No differential correction data support is required. 3. Users do not need to pay communication data fees for transmission between the user terminal and the augmentation system. 4. Data privacy issue: the data is only owned by the user (the car manufacturer). 5. Global availability. 6. Product quality responsibility is clear and borne by us. 7. High availability, good data integrity. 8. RAC is easy to install on mass-produced vehicles! |
