Mingjiada Electronics, as a seasoned supplier in the semiconductor sector, has accurately identified the industry shift in satellite communications from ‘specialised and exclusive’ to ‘consumer-accessible and inclusive’. Focusing on satellite navigation/positioning chips, we leverage our deep expertise in multi-system technologies including BeiDou, GPS, and Tiantong to deliver highly reliable, high-performance chip solutions for diverse applications such as automotive electronics, consumer devices, industrial monitoring, and aviation. This empowers our clients to seize market opportunities.

Satellite Navigation/Positioning Chips: Precise Positioning, Establishing Spatio-Temporal Reference
As the ‘spatio-temporal perception core’ of terminal devices, satellite navigation/positioning chips achieve precise calculations of location, velocity, and time by receiving signals from multiple satellite systems.

Mingjiada Electronics supplies navigation and positioning chips across three core categories, comprehensively meeting the accuracy and functional requirements of diverse scenarios:
(1) Classification by System Compatibility
1. Single-System Positioning Chips: Specialising in high-precision positioning for individual satellite systems, including dedicated BeiDou chips and GPS chips. These support full-band signal reception for specific systems, offering low power consumption and cost-effective advantages. Suitable for industry terminals with defined positioning requirements, such as dedicated BeiDou navigation terminals or single-system tracking devices. Cold start time ≤40 seconds, with positioning accuracy reaching 10-metre level.
2. Multi-mode, multi-frequency positioning chips: Compatible with global mainstream satellite systems including BeiDou-3, GPS, GLONASS, GALILEO, QZSS, and SBAS. Supports combined positioning across L1, L2, and L5 frequency bands. Manufactured using an advanced 22nm process, it integrates 144 signal channels enabling seamless switching between multi-system joint positioning and single-system independent positioning. Cold start time is reduced to 25 seconds, with hot start <1 second. Horizontal positioning accuracy reaches up to 0.8 metres, while RTK fixed accuracy achieves sub-2cm precision. Widely deployed in high-accuracy applications including autonomous driving, surveying and mapping, precision agriculture, and security monitoring.

(II) Classification by Functional Integration
1. Pure Positioning Chip: Focuses on core positioning and timing functions, incorporating RAIM autonomous integrity monitoring and anti-spoofing algorithms. PPS timing accuracy is <5ns, providing stable support for scenarios demanding stringent time synchronisation, such as power grids and communication base stations.
2. Integrated Positioning-Communication Chips: Combine navigation positioning with short message communication capabilities, supporting BeiDou short message emergency transmission. Also feature dual-mode GPS/BeiDou positioning with extensive external interfaces (UART/SPI/GPIO/I2C), suitable for outdoor IoT devices and disaster relief terminals in areas without terrestrial network coverage.

(III) Classification by Application Scenario
1. Automotive-grade positioning chip: Operates within a wide temperature range of -40°C to +85°C, supports DR-based navigation applications with velocity accuracy of 0.1m/s. Suitable for automotive navigation, fleet management, and autonomous driving data acquisition.
2. Consumer-grade positioning chips: Featuring highly integrated SOC designs with compact dimensions (minimum 3.25mm × 3.25mm) and power consumption ≤0.4W, suitable for portable terminals including smartphones, smartwatches, and handheld navigation devices;
3. Industrial-grade positioning chip: Enhanced anti-interference capability and stability, supporting D-GNSS and A-GNSS assisted positioning with reacquisition time <1 second. Suitable for complex environmental applications including hydrological monitoring, mineral resource exploration, and disaster prevention and mitigation.

Mingjiada Electronics' satellite chip supply system possesses three core advantages:
Firstly, comprehensive coverage spanning mainstream navigation, positioning, and communication chip categories, meeting diverse requirements from consumer to industrial applications and civilian to military use;
Secondly, high-performance adaptation with all chips undergoing rigorous environmental reliability testing, supporting wide-temperature operation, radiation resistance, and low-power design for extreme scenarios including space, deep-sea, and desert environments;
Thirdly, domestic adaptation, with deep support for indigenous satellite systems like BeiDou and Tiantong, facilitating core chip substitution in terminal devices and safeguarding supply chain security.
