Calian's TP5387 Smart Antenna SDK is a multi-band (L1/L5), multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (IMU). It integrates STMicroelectronics' Teseo V receiver in a Quectel LG69TAP module with a TW5387 Tallysman Accutenna® antenna and is compatible with Skylark Cx and Nx RTK. It comes with the TruPrecison SDK application, which provides an NTRIP connection to stream Skylark corrections to the Smart Antenna via RS-422 or RS-232, depending on the variant.
