ROLAVI HELICAL ROLAVI HELICAL is a pocket device that works With your Android smartphone or tablet. It can used for Windows device too. This is a perfect solution to get centimeter level of precision in your projects. Description: The ROLAVI HELICAL is a high-precision GNSS receiver that operates connected to an Android smartphone or tablet and you can get high precision via RTK, NTRIP and PPK. Apart from that, the ROLAVI HELICAL has a SD port to save UBX. This can receive data via USB cable or Bluetooth. Main Advantages: • • • • • • • • • • Uses the same GNSS L1/L2/e5 technology found in professional receivers with stateof-the-art components Simultaneous reception of all constellations: GPS, GLONASS, GALILEO and BEIDOU Multi-band NTRIP corrections with fast convergence times and robust performance, offers centimeter-level of precision with a Fix solution in seconds Allows Geodetic Surveys and Photogrammetry with high-precision geotagging Includes its own multi-band helical GNSS antenna. Data transfer connection via USB port and Bluetooth Compatible with GIS and Photogrammetry Applications that operate with NMEA data Rugged plastic enclosure In short: Centimeter-level precision in a small, very low-power module. Working modes: RTK, PPK, NTRIP, Static and PPP. Module Components: 1. Multi-band Antenna Helical 2.
