The Difference between Beidou Single Module and Dual-mode

PublishTime： 2024-06-19 Article Source：SKYLAB Official Website

The Beidou single module refers to a mode that only uses the BeiDou satellite navigation system for positioning. The Beidou Satellite Navigation System is a satellite navigation system independently developed by China, with characteristics such as global coverage, high accuracy, and high reliability.

In some specific application scenarios, it may be necessary to use Beidou single module positioning, such as:

1.High security and high confidentiality industries: Some industries that require high security and confidentiality, such as finance and military, may prefer to use BeiDou single module positioning to reduce reliance on other satellite navigation systems.

2. Specific regions or environments: In certain regions or environments, signals from other satellite navigation systems may be interfered with or restricted, while signals from the BeiDou satellite navigation system may be stronger or more stable. In this case, using a single BeiDou module for positioning can achieve better positioning results.

It should be noted that Beidou single module positioning may be affected by factors such as satellite signal coverage and accuracy in some cases. In practical applications, other satellite navigation systems or positioning technologies are usually combined to improve the reliability and accuracy of positioning. In addition, with the continuous development and improvement of the Beidou satellite navigation system, its application in the field of mass consumption will also become increasingly widespread.

The difference between Beidou single module and dual-mode

The difference between Beidou single module and dual-mode is mainly reflected in the following aspects:

1.Satellite signal reception: The BeiDou single module can only receive signals from the BeiDou satellite system, while the BeiDou dual module can simultaneously receive signals from both the BeiDou satellite system and other satellite navigation systems (such as GPS, GLONASS, etc.).

2. Positioning accuracy: In an ideal situation, dual-mode products can utilize signals from multiple satellite systems to improve positioning accuracy and reliability.

3. Application scenario: The BeiDou single module is suitable for use in areas with specific requirements for the BeiDou satellite system or with good BeiDou signal coverage. The Beidou dual-mode is more suitable for use in scenarios that require wider satellite signal coverage and higher positioning accuracy, such as in urban canyons, mountainous areas, or complex environments.

4. Cost: Generally speaking, BeiDou dual-mode equipment may have higher costs compared to BeiDou single module equipment, as it needs to support the reception and processing functions of multiple satellite systems simultaneously.

In practical applications, the choice of Beidou single module or dual-mode should be determined based on specific requirements and usage scenarios. If positioning only needs to be carried out within the coverage range of the Beidou signal and does not require high accuracy, a single Beidou module may be an economical choice. If more accurate positioning is needed in a wider area, or if there is a high requirement for the reliability of positioning, Beidou dual-mode may be more suitable.
