*Main Features of the GNSS RTK GPS:

Multi-constellation tracking

220 tracking channels.
Supports GPS, GLONASS, GALILEO, BDS, SBAS.
NGS approved GNSS antenna.

Intelligent operation

Equipped with a smart speaker guiding the whole operation.
Multi one-button functions make fieldwork easier, such as auto base setup by one button, the rover can get fix solution once it is turned on.

Diversify RTK application

Optional transceiver UHF radio

The transceiver UHF radio enables the working mode to be switchable between base and rover.
2-watt HI-TARGET internal UHF radio and 2-watt Pacific Crest TrimTalk© internal UHF radio are optional. Pacific Crest TrimTalk© internal UHF radio is compatible with other radios.
Removable internal UHF radio enables users to fix or exchange simply.

Seamless operation in CORS system

Built-in GPRS/GSM/3G module ensures that the V30 works perfectly with network RTK positioning.

Long-life battery

Powered by 5000mAh Li-ion battery.
Static working time 13 - 15 hours.
RTK Rover (UHF/GPRS/GSM) working time 10 - 12 hours.
RTK Base working time 8 - 10 hours.

Rugged and unique design

IP67 dust/water protection.
Withstands 3-meter natural fall onto concrete.
Rapid tracking and perfect avoidance or reduction of obstruction and multipath effect to ensure superior positioning capability.

*Main Application of the Differential GNSS RTK GPS:

Working Mode Option:

*If you need to do surveying at a palce where is terrain open, without too much control in radio use:

Measuring distance within 3Km: Better to use internal radio working mode;

Measuring distance over 3Km: Better to use external radio working mode.

*If you need to do surveying at a place where the radio use is in strick control,but the network coverage is very good:

If have CORS Site at local,you could choose network RTK working mode;

If don't have CORS Site at local, you could building a simple server.

*If you need to do surveying at a place where radio use is in strick contol,and the network coverage also not fine:

Under this condition,you could choose to use Stop & Go Surveying mode.
