DGPS Instruments (Differential GPS) are advanced navigation tools that enhance GPS accuracy by using a reference station to correct satellite signals. Made from durable metal, plastic, and electronic components, key parts include receivers, antennas, and correction signal processors. DGPS instruments are essential in industries like surveying, agriculture, construction, and marine navigation for precise positioning. They use cutting-edge satellite communication and signal processing technologies for real-time corrections. Clients benefit from improved accuracy, reducing errors in mapping, land surveying, and fleet management. Specifications typically include real-time data processing, long-range functionality, and high-resolution accuracy, making them invaluable for critical operations.
