  • Dual-frequency GNSS observables from smarpthones: ionosphere and multipath
    As it is known, on May 2018 Xiaomi introduced to market its new flagship smartphone, the Xiaomi Mi 8. For GNSS enthusiats, this was a huge milestone since this is the first device to have the Broadcom BCM47755 GNSS chipset, which delivers dual-frequency (L1/L5) GNSS measurements. In particular, the signal properties at the GPS L5

  • ARGONAUT + JASON for Survey Applications
     Abstract This post attempts to compare the performance of a geodetic-grade GNSS receiver (Septentrio AsterRx) and a low-cost one (Rokubun Argonaut) in a static scenario. The results indicate similar accuracies despite the differences in price and hardware. Rokubun’s Argonaut GNSS receiver achieves 1.8 cm RMS when compared to the truth provided by a Septentrio AsteRx

  • GNSS carrier phase from Nexus 9
    As it is known, there is an active development in using Android ranges for PPP and RTK, but these require the phase observables, which, as of the time of writing this post, only few devices provide. Even if they are provided, obtaining the carrier phase might not be as straightforward as in commercial GNSS receivers. In

  • Rokubun sponsoring the 7th BCN Drone Center UAV Remote Sensing Applications course
    Rokubun is glad to participate as sponsor in the BCN Drone Center next UAV Drone Remote Sensing Applications course (12th – 16th June 2017).  Friday 16th June we will present our new ARGONAUT solution for affordable accurate geo-location of UAVs/drones and will as well give a talk about SAR (Synthetic Aperture Radar) remote sensing. We

  • Argonaut’s first maiden flight
    Argonaut (Rokubun’s GPS receiver) is a positioning device based on a Ublox chipset (NEO-7P, to be migrated to the newest NEO-M8T). The receiver provides GPS fixes and single frequency (L1) raw (code and phase) measurements, as well as inertial measurements from the embedded 9 DOF inertial unit (Invensense MPU9250, with accelerometer, gyroscope and magnetic field). Additionally,
