OEM Available High Precision Surveying l1/l2 GPS
It is designed to meet high quality standards at an affordable price. It is outstanding in its
class, with a rugged design and user-friendly functions.
V30 GPS is 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.
Seamless operation in CORS system,Built-in GPRS/GSM/3G module ensures that the V30 works perfectly with network RTK positioning.
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.
The picture of l1/l2 GPS
What's the advantage of our l1/l2 GPS?
Independence: No external cable or battery is needed, so you can put it where you want.
Compatibility: It can both directly transmit and forward in same-frequency or pilot-frequency
Multi-channel: It has 116 UHF channels, and supports custom channels.
Power: 5W/10W/20W/35W adjustable
Distance:Its max working distance is 50 km, which depends on the setting altitude.
Resistant features: waterproof, dustproof, broken-resistant performance.Intelligentialized self-diagnosis function
