Luka is a compact and lightweight RTK-capable smart GNSS receiver that utilizes calibration-free tilt compensation, removing the need to keep the survey pole upright and providing surveyors with enhanced versatility and efficiency. Housed in a rugged IP68-rated enclosure, it can withstand the most challenging of field conditions.
Based around a high-performance 1568-channel multi-constellation and multi-frequency GNSS board and an advanced anti-jamming antenna, Luka can transmit and receive corrections data through 4G, WiFi and UHF radio. The receiver also includes a free subscription to Tersus Caster Service (TCS), enabling it to be used as a base station that can broadcast corrections data to drones and other rovers via mobile networks.
Luka is available in four variants, with options including tilt compensation and UHF radio.
