Carlson VASCO-B GNSS Base Station
The Carlson VASCO®-B is a high-precision, multi-purpose GNSS base station designed for permanent installation in both office and harsh outdoor environments. Suitable for local site setups or full network configurations, it delivers reliable, high-accuracy RTK corrections for a wide range of GNSS applications.
Precision GNSS Performance
Featuring a 448-channel high-precision GNSS receiver, the VASCO-B tracks all major constellations including GPS, GLONASS, Galileo, BeiDou, NavIC and QZSS.
RTK Accuracy (RMS):
-
Horizontal: 0.6 cm + 0.5 ppm
-
Vertical: 1 cm + 1 ppm
It supports standard protocols including RTCM 3.4, CMR, CMR+, NMEA and RINEX, ensuring compatibility with surveying equipment and correction services.
Flexible RTK Broadcasting & Connectivity
RTK corrections can be transmitted via:
-
4G LTE (with 3G fallback)
-
UHF radio (configurable TX & RX)
-
Network/NTRIP
A built-in remote web interface allows straightforward configuration, monitoring and troubleshooting.
Connectivity options include dual Ethernet (M12), RS232/RS422 serial ports, Bluetooth, Wi-Fi, external antenna connections, and a wide 10–30 V DC power input range.
