Overview
- Provides realtime accuracies of 60cm when operating with the OmniSTAR satellite
- COAST™ technology uses old differential corrections for up to 40 minutes, or more, without significant performance loss
- Upgradeable to output messages up to 20Hz
Sub-metre realtime GPS using either OmniSTAR or the Australian AMSA marine beacon system.
Efficiently complete your work with the
Hemisphere R120 GPS Receiver. Sub-meter accuracy when using a DGPS signal. When used autonomously, accuracy of less than 2.5 meters is achieved.
Many different correction options for different operational environments make this a multi-purpose and versatile system. The user interface is simple so you can easily configure your system and the status LED's let you know at a glance the condition of the receiver.
When consistency and accuracy are integral, you can add the 20Hz update. Any Hemisphere R100 series GPS (including the R120) can be updated to an output rate of 20Hz with the additional
20Hz Update. Hardware does not need to be changed, the code just needs to be entered to unlock this feature.
