Description

In production

The Siderion SP0702 is an affordable, compact, and high-precision triple-band L1/L2/L5 GNSS RTK (Real-Time Kinematic) device.

Powered by the latest generation of u-blox ZED-F20P modules, the SP0702 supports concurrent reception of GPS, Galileo, BeiDou, QZSS, and NavIC signals. Consequently, the device delivers reliable performance and fast convergence, achieving centimeter-level accuracy in seconds.

Its mini PCI Express (mPCIe) interface makes it ideal for integration within embedded systems, drones, industrial tablets, ruggedized laptops, and other compact computing platforms.

The SP0702 operates across a temperature range from -40°C to +70°C.
