Does Amap Use Beidou Satellites? The Truth Revealed!

While "Amap" and "Beidou satellite" seem closely related, this is not actually the case. Amap is an internet-based map service application, while Beidou satellite is the national satellite navigation infrastructure, which is one of the data sources for internet map services. So, which one do navigation software like Amap use, Beidou satellite or GPS? The answer is not so simple, let's delve into the mystery.

First, we need to make it clear: Amap does not directly interact with Beidou satellite system. The working principle of navigation software like Amap is to use the positioning coordinates of the phone, combined with its own stored map data, to achieve the matching of positioning and map, and finally complete navigation route planning and other functions. The positioning function of the phone is in charge of the satellite positioning chip of the phone, not controlled by navigation software like Amap.

In other words, the positioning system used by the phone's positioning chip determines the positioning system used by the navigation software. If the phone's positioning chip supports the Beidou system, then navigation software like Amap will naturally use the Beidou system for positioning. Vice versa.

So, are there any chips on the market that support Beidou satellite navigation positioning? The answer is yes! In fact, since 2013, the Beidou civilian market has entered a period of rapid development. The country has invested a lot of money in carrying out Beidou satellite navigation application demonstration projects in many cities across the country, such as Beijing, Shanghai, Guangzhou, Hubei, Hunan, Henan, Shandong, Gansu, etc. The first high ground of Beidou's civilian use is transportation application, which is mainly reflected in the vehicle driving recorder of "two passenger cars and one dangerous goods". At present, about 5 million trucks, buses, and dangerous goods vehicles across the country have upgraded from the original GPS positioning terminal to the Beidou positioning terminal.

In addition, in recent years, popular wearable devices have also adopted the Beidou positioning system. There are many domestic companies engaged in Beidou navigation chip research and development, including well-known ones such as MediaTek (MTK), HiSilicon, Taitou, Huaxun, and Microchip Zhongke, etc. These companies currently have annual shipments of tens of millions of chips, with considerable output value. The price of Beidou chips is also relatively affordable, ranging from 10 to 200 yuan, with most concentrated around 30 yuan. As Huawei and other mobile phone manufacturers have adopted Beidou positioning, the scale of Beidou's civilian market will further expand.

Returning to the question of whether Amap uses Beidou, currently many phones' satellite positioning chips support dual-mode positioning of Beidou + GPS, and they output positioning results (NMEA0183 protocol format) to the phone, and navigation software like Amap reads these positioning results to perform navigation positioning. Therefore, as long as the phone's positioning chip supports Beidou, then navigation software like Amap will use Beidou for positioning.

In short, navigation software like Amap does not directly use the Beidou satellite system, but obtains positioning information through the phone's satellite positioning chip. In the future, as the application range of the Beidou system continues to expand, and mobile chip manufacturers strengthen their support for Beidou, the proportion of navigation software like Amap using Beidou for positioning will become increasingly higher.
