    ER-SR-680 High Precision Storage Type Receiver

    Introduction

    ER-SR-680 High Precision storage receiver is a new design that supports BD, GPS and GLONASS system eight frequency high precision reference station receiver type products. The receiver-based embedded Linux operating system uses the multi-frequency high-performance SOC chip NebulasTM system with Ericco’s completely independent intellectual property rights.

    The product supports secondary development, the built-in storage can hold continuous observation data for one month, the built-in 10000mah intelligent lithium battery, has friendly human-computer interaction, Bluetooth, WiFi, 3G WCDMA data modules. It can also easily realize the access operation of PC or PDA to the host ER-SR-680. It has strong anti-interference ability and high stability, and can meet the needs of unattended operation of base stations. Therefore, it is widely used in surveying and mapping, meteorology, earthquake, displacement monitoring, high-precision positioning applications such as scientific research.
