Calian's TP5790 Smart Antenna SDK is a multi-band (L1/L2), multi-constellation integrated GNSS receiver/antenna with Inertial Measurement Unit (IMU). It integrates u-blox' ZED-F9R receiver with a TW5790 Tallysman antenna and is compatible with all three Skylark variants. It comes with the TruPrecison SDK application, which provides an NTRIP connection to stream Skylark corrections to the Smart Antenna via USB or RS-232, depending on the variant.
