Overview
- Will operate from OmniSTAR signal, *OR* AMSA marine beacons in Australia
- Realtime accuracies of 60cm when using OmniSTAR or AMSA beacons
- Uses a standard USB port for communication with PC
Sub-metre realtime GPS (using either OmniSTAR or the Australian AMSA marine beacon system) for any PDA, tablet or computer, or less than 5 metres using a Garmin handheld.
The
Hemisphere R131 DGPS receiver, incorporates GPS, AMSA beacon receiver, AND OmniSTAR VBS receiver. Provides realtime accuracies of 60cm when operating with either an AMSA signal, or the OmniSTAR satellite.
The
R131 provides new and convenient physical advantages, including a new design with a rack mountable enclosure, front facing display, 1PPS output via an SMA connector, and a new soft power switch in lieu of the traditional mechanical power switch. The soft switch allows for ease of use when turning the R131 on/off when the R131 is rack mounted. In addition to the new features, Hemisphere GPS has added a new metal power connector that provides a durable connection.
