A Field Calibration Solution to Achieve High-Grade-Level Performance for Low-Cost Dual-Frequency GNSS Receiver and Antennas

Low-cost dual-frequency receivers and antennas have created opportunities for a wide range of new applications, in regions and disciplines where traditional GNSS equipment is unaffordable. However, the major drawback of using low-cost antenna equipment is that antenna phase patterns are typically poorly defined. Therefore, the noise in...

Perspectives of Cost-Efficient GNSS Equipment for Wide-Spread and High-Quality Meteorological and Positioning Applications

Whether in cars, smartphones, watches or fitness-trackers - the use of Global Navigation Satellite Systems (GNSS) has become a part of our daily life. Currently there are more than 100 GNSS satellites in orbit. They are routinely utilized for positioning and timing purposes, but their signals can also be used to monitor our environment. The...

High quality zenith tropospheric delay estimation using a low-cost dual-frequency receiver and relative antenna calibration

The recent release of consumer-grade dual-frequency receivers sparked scientific interest into use of these cost-efficient devices for high precision positioning and tropospheric delay estimations. Previous analyses with low-cost single-frequency receivers showed promising results for the estimation of Zenith Tropospheric Delays (ZTDs)....

Potential of cost-efficient single frequency GNSS receivers for water vapor monitoring

Dual-frequency Global Navigation Satellite Systems (GNSSs) enable the estimation of Zenith Tropospheric Delay (ZTD) which can be converted to PrecipitableWater Vapor (PWV). The density of existing GNSS monitoring networks is insufficient to capture small-scale water vapor variations that are especially important for extreme weather...
