How Can We Integrate RTK-Grade GNSS Into Our Industrial PCs Without Complex Driver Development?

The LS2603x-52Q offers plug-and-play USB interface integration in standard PCIe Mini formats, eliminating driver complexity while delivering multi-constellation RTK positioning. With operating temperatures from -40°C to 85°C and low 51mA power consumption, it's engineered for demanding industrial environments. Contact us to receive integration guidelines and technical specifications tailored to your IPC platform requirements.

The LS2603x-52Q series features innovative hybrid ephemeris prediction technology that dramatically reduces cold start time to less than 15 seconds. The dual-mode prediction system includes self-generated ephemeris valid for 3 days with automatic updates, and server-generated ephemeris valid for 14 days, both stored in on-board flash memory. This industrial gnss card supports PPS output through USB and incorporates a built-in micro battery for system data retention, ensuring rapid satellite acquisition after power cycles. With an operating temperature range of -40°C to 85°C and compact PCIe Mini form factor, the LS2603x-52Q delivers enterprise-grade reliability for automotive navigation systems, industrial automation, surveying equipment, and precision agriculture applications requiring centimeter-level accuracy through RTK functionality.

LS26030-52Q and LS26031-52Q are GNSS modules incorporated into the PCIe Full-Mini card or PCIe Half-Mini card.
LS26030-52Q and LS26031-52Q are GNSS modules incorporated into the PCIe Full-Mini card or PCIe Half-Mini card.

LS26030-52Q and LS26031-52Q are GNSS modules incorporated into the PCIe Full-Mini card or PCIe Half-Mini card. These GNSS modules can provide superior sensitivity and performance even in urban canyon and dense foliage environment. Besides, the USB interface makes these modules easy to integrate into the laptop.

These modules support hybrid ephemeris prediction to achieve faster cold start. One is self-generated ephemeris prediction that is no need of both network assistance and host CPU’s intervention. This is valid for up to 3 days and updates automatically from time to time when GNSS module is powered on and satellites are available. The other is server-generated ephemeris prediction that gets from an internet server. This is valid for up to 14 days. Both ephemeris predictions are stored in the on-board flash memory and perform a cold start time less than 15 seconds.
