Summary
Drones are revolutionizing polar research, but Global Navigation Satellite System (GNSS) choices for drones show varied usage. No specific GNSS augmentation pattern strongly correlates with improved positioning accuracy in these critical environments.
Area of Science:
- Environmental science
- Geosciences
- Remote sensing
Background:
- Aerial unmanned vehicles (drones) are increasingly used in scientific research, offering an alternative to manned aircraft.
- Cryospheric regions like Antarctica and the Arctic are key areas for scientific study, requiring reliable data collection methods.
Purpose of the Study:
- To examine the use and performance of Global Navigation Satellite Systems (GNSS) for drones in polar scientific research.
- To provide insights into GNSS choices, including augmentation systems, for drone operations in the Arctic and Antarctic.
Main Methods:
- A survey of polar scientists using drones was conducted in April 2019, collecting data on GNSS usage and positioning accuracy.
- Data from 16 countries were analyzed, including multiple regression analysis to identify relationships between GNSS augmentation and accuracy.
Main Results:
- Survey results indicate varied GNSS usage: 14.71% used Galileo, 27.94% used GLONASS, and 45.59% used GPS, with many using multiple systems.
- Multiple regression analysis revealed no strong correlation between specific GNSS augmentation patterns and enhanced positioning accuracy.
Conclusions:
- Drone technology is transforming polar research, but GNSS selection and performance require further investigation.
- Future studies should focus on the impact of phase scintillation on all major GNSS (BeiDou, Galileo, GLONASS, GPS) for improved drone navigation in polar regions.

The polar coordinate system offers an alternative to the Cartesian coordinate system for specifying points in a plane, using a distance and an angle instead of x and y coordinates. This system is particularly advantageous in situations involving circular or rotational symmetry, such as in physics or engineering problems involving waves, oscillations, or orbital paths.Defining Polar CoordinatesIn polar coordinates, a point is represented as P(r, ��), where r is the radial distance...
