2 DG14 and DG16 Board & Sensor Reference Manual
The DG16 is designed for stand-alone and differential GPS (DGPS) operation; it
can operate as a base (reference) station or a remote (rover) station, providing or
using real-time differential GPS corrections in RTCM SC-104 format
(Version 2.2).
This chapter describes DG16 hardware and functionality, describes the RF
interface connector and the power/input/output connector, options, firmware
upgrades, and lists power requirements and environmental specifications.
