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 Nx RTK. It comes with the TruPrecison SDK application, which provides an NTRIP connection to stream Skylark corrections to the Smart Antenna via RS-232.
