Details
An all-in-one marine GNSS receiver design combines the antenna and module for simpler installation.
DB9 RS-232 wiring and mechanical dimensions help confirm fit and power/serial connections before installation.
Multi-constellation reception and multiple connection methods support flexible integration across marine and industrial equipment.
Compact dimensions make the unit easier to mount on boats and equipment where space is limited.
Serial data output over RS-232 supports common GNSS workflows, from positioning to timing, using satellite signals.
Typical uses include ocean vessels, base-station timing, driving-test systems, and unmanned boats; one receiver is included.
