eBase 20

Portable GNSS Base Receiver

The eBase 20 is a professional and portable GNSS base receiver. With a high-precision algorithm and tracking multiple frequencies, eBase 20 is specifically designed to work as a GNSS base station. Combining a 4G modem and internal radio, eBase 20 is a perfect choice for a base station. The eBase 20 is ideal for applications such as UAV, USV, agriculture, intelligent driving, surveying and mapping, etc.

Multi-constellation and Multi-frequency
With 1408 channels of GNSS tracking, it provides stable and reliable accuracy. All GNSS signals come with the standard, including GPS, BDS, GLONASS, GALILEO, QZSS, and SBAS.

Integrated Tx/Rx UHF and 4G modem
The built-in Global 4G Network and TX/RX radio module allow eBase 20 to work perfectly as a base station to transmit GNSS corrections.

High-precision and Cost-effective
Embedded with a high-precision GNSS module, eBase 20 provides high performance as a GNSS base station at a low cost. Easy to carry and simple setup process improves work efficiency.

Instant Base Station Moved Alarm
When the base station is displaced, eBase 20 will give a warning in real time to prevent error data to be collected. In addition, there is also a buzzer alarm when the battery is low and the receiver is not activated.

Smart Base Station Service
The smart base station service works while connected to the CORS and gets an accurate position as a known point.

Web UI
It allows users to view position status, download data, and update firmware from the Web user interface with any smartphone, tablet, or PC.
