Meridian SuperBase
Long-Lasting Smart GNSS Base
The SuperBase features a built-in 5W high-power radio with a maximum coverage distance of up to 35 km. With one person, one data collector, and one SuperBase, on-site setup is as easy as setting up a tripod-setup efficiency is boosted by 3x, giving you more time for surveying and less for debugging. Paired with dual removable batteries, it delivers up to N hours of runtime and supports hot‑swapping without powering off, enabling unlimited continuous surveying. The high‑definition touch screen provides real‑time base station status at a glance-everything is managed on a single screen.
Up to 15 Hours of Operating Time as a Base Station
When used as a base station, the SuperBase with dual removable batteries delivers up to 15 hours of uninterrupted operation on a single charge, completely eliminating the need for external batteries or frequent battery swaps.
Dual Hot-swappable Batteries
Dual removable 7000mAh lithium batteries support hot swapping without shutdown, eliminating the need for external batteries and reducing downtime.
Up to 35 km Working Distance
The 5W high-power radio, paired with our dedicated protocol Meridian Link，can work ata maximum distance of up to 35km,extending base station range for uninterrupted surveying.
HD Touchscreen, Everything at a Glance
The 1.39-inch HD touchscreen displays satellite tracking, coordinates, battery level, and communication status in real time. The screen features guided, tap‑based interaction throughout-no need to memorize any parameters. Even without a controller, you can easily complete all instrument setup operations.
1408 Channels, Lock Every Satellite
SuperBase works with any satellite and any frequency, supporting GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS satellite systems as well as PPP services, delivering reliable RTK corrections to improve both surveying accuracy and efficiency.
