Abstract
To overcome the disadvantages of complex structure design, high power consumption, huge volume and prominent cost of traditional high-precision GNSS terminals, a dual band multi-system GNSS terminal based on high precision GNSS module is proposed in this study. The terminal adopts low profile, broadband quadrifilar helix antenna (QHA) and centimeter level RTK navigation and positioning module, combined with dual channel low-noise amplifier circuit and laminated shielding structure. Peak gain of the QHA in the whole working frequency band is greater than 0 dBi with the axis ratio less than 1.1 dB, and the maximum gain is greater than 2.5 dBi, which shows excellent circularly polarized radiation and broadband working characteristics. In the open test scenario, the effectiveness of capturing satellite and RTK performance are analyzed. The carrier-to-noise density ratio (C/N0) of multiple Galileo and Beidou satellites is close to or even greater than 50 dB-Hz. The static RTK positioning results show that the horizontal and elevation accuracy of internal coincidence is 0.84 cm and 1.24 cm, respectively. Finally, the sensitivity, single point positioning and velocity accuracy are quantified in the wireless simulation test system. Research results indicate that the terminal not only has the excellent characteristics of small volume, light weight, low power consumption and high portability, but also can achieve centimeter positioning accuracy. It’s especially suitable for the requirements of small bearing platforms, such as Unmanned Aerial Vehicle (UAV), hand-held and piggyback operation and other application scenarios.
