As a cost-effective and miniaturized GNSS receiver, the NET660i-H is designed for the construction of the Beidou ground-based augmentation system. Additionally, it features a built-in Linux operating system and is developed with completely independent intellectual property rights. Moreover, it boasts rich interface types, diverse communication methods, and supports large-capacity data storage. Furthermore, the NET660i-H supports full system and frequency, as well as a dual-antenna directed positioning solution with dual-antenna independent differential output capability. Ultimately, it is the best choice for the construction of the mechanical intelligent control system.
