RH-1
・Outline of product
RH-1 is GPS receiver in GRS-1 to measure the GPS data in real time.
RH-1 supplies the electric power to GRS-1 by two battery and outside AC power, and
enables the operation of GRS-1 of long time.
・Surveying to use the wireless modem
This method of GPS survey allows the operator to reduce the point occupation time, thus permitting
field crews to survey many more points compared to the other methods available.
Real Time Kinematic Surveying
In RTK surveying, one receiver serves as the reference station. The receiver conducts observations
with its antenna affixed to a stationary tripod or another device. The second receiver functions as a
rover, and conducts observations (using an antenna) affixed to a mobile pole and moved to
observation points.
Unlike post-processed kinematic surveys, RTK surveys uses a communications link between the
Base and Rover. Using a radio modem link, the Base receiver transmits its measurement and location
data to the Rover receiver. The Rover, based on the transmitted data and its own observation data,
immediately conducts a baseline analysis and outputs the results.
The GPS receiver receives the correction data that RH-1 received through the connection by
Bluetooth.The GPS receiver uses GRS-1 usually.

About BATTERY LED
The color of the battery LEDs display the status of th remaning charge for the
corresponding battery and is the same for LEDs:
Green More than 60%
Orange 20% to 60%
Red Less than 20%
No light There is not battery
The blink interval and length of time lit of the battery LEDs display the status
of the battery when in use:
In use:
a 2second light in 0.5 second intervals
*Color is depended on the remaining charge
Not in use
Solid light
*Color is depended on the remaining charge
Error Rapid red blink
(EX. Open the battery’s cover)
The charging with the AC adaptor
The AC Adaptor supports charging-on-the-run for RH-1
With the adapter plugged into an AC outlet and the batteries installed,the
batteries will also be charged.
The charging status varies depending on the state of the batteries.
Both battery LEDs use the same blink pattern while the corresponding battery
charge.
While charging,the battery LED for the charging battery blinks in 2 second
intervals.
Solid green light battery charging is completed
Red blink Charging battery
Solid Orange Not in charging
