About the Aquila
The Aquila chip is UniStrong's first four-channel GNSS wideband RF chip. It incorporates signal reception requirements for future multi-constellation, multi-frequency high-precision GNSS receivers, as well as UniStrong's L-band satellite-based augmentation signal reception requirements. Aquila consists of three GNSS RF channels and one L-band RF channel, which can be configured to operate simultaneously or independently. The chip supports single-frequency, multi-frequency, and L-band satellite-based augmentation positioning, meeting the operational needs of various receiver configurations such as single-antenna and dual-antenna systems, and is widely applicable across diverse high-precision positioning applications. The "Tianying" chip is UniStrong's first four-channel GNSS wideband RF chip. It integrates the signal reception requirements of future multi-constellation multi-frequency high-precision GNSS receivers with the signal reception needs of UniStrong's L-band satellite-based augmentation system (SBAS/Atlas). Tianying consists of three GNSS RF channels and one L-band RF channel, which can be configured to operate concurrently or independently. The chip is suitable for single-frequency, multi-frequency, and L-band augmentation positioning, satisfying the operating requirements of various receiver types such as single-antenna and dual-antenna, and can be widely applied in diverse high-precision positioning fields.
Key Features
● Full-constellation full-frequency coverage, supporting reception of all satellite navigation signals; ● Three GNSS RF channels, each capable of covering all satellite signals in the 1.16–1.3 GHz and 1.53–1.62 GHz frequency bands; ● One narrowband RF channel supporting narrowband signals; ● Four channels can operate concurrently or be configured independently; ● Fully differential design to reduce crosstalk and spurious signals; ● IQ analog/digital IF output; ● Standard SPI digital control interface; ● Four-channel operating current of 169 mA, powered by 1.8 V; ● QFN80L, 9 mm x 9 mm package
Applications
Integrated into high-precision positioning or heading OEM boards, it can be applied in various high-precision fields such as surveying and mapping, deformation monitoring, precision agriculture, aviation and marine navigation, digital construction, autonomous driving, UAVs, mobile GIS, and intelligent transportation systems.
"Tianying" is a four-channel wideband RF chip designed by combining the signal reception requirements of future multi-constellation multi-frequency high-precision GNSS receivers and L-band satellite-based augmentation. Comprising three GNSS RF channels and one L-band RF channel, it can be configured to operate concurrently or independently, meeting the requirements of single-frequency, multi-frequency, and L-band satellite-based augmentation, as well as single-antenna, dual-antenna, and triple-antenna receivers.
