The DL-4 series is a high performance, high accuracy GPS receiver that features an integrated memory card and LCD display that eliminates the need for a separate data collector. Dual battery management and a built-in scheduling function allow the user to pre-program multiple logging sessions for stand-alone (autonomous) operation.

The DL-4plus also provides support for an external inertial measurement unit (IMU). With NovAtel’s SPAN™ Technology, the addition of inertial capabilities results in continuous positioning even during short outages or reduced satellite coverage. The system is also ideal for high-dynamic applications, providing highly accurate position and attitude measurements at 100 Hertz rates.
